Many top Chinese engineering students will choose to study abroad for postgraduate or Ph.D., but my UHV teacher said that this law does not hold in the field of UHV power transmission.
@@robertlomax543 nope. It’s 3300km ±1100 kv UHVDC from Changji to Guquan. The longer the transmission line, the more economical it is, but it is true that the cost of this line is very high, so currently there is only one line.
@@robertlomax543 Ultra High Voltage Transmission are almost exclusively DC. Power frequency AC transmission goes out of phase roughly at a distance of ~ speed of light / frequency = several thousand kilometers. At such a distance, DC transmission is the only option. Also, solid state transformers / converters / inverters are much more energy efficient than traditional iron-core based transformers, as iron loss is zero in solid state electronics.
I spent a week in August in Florida where my grandmothers took me out to eat every night. You will not find a building without AC. In those months, you need to wear a t-shirt and carry a sweatshirt because you'll be inside your car with the AC blasting, then in 100 degree weather for 2 seconds before entering a restaurant where the AC makes it freezing. lol
I live in California and every summer it gets to 110, and every winter below freezing. A lot of us dont have AC's here cuz they just break from running all the time

I find it kind of funny because about 10 years ago (or even longer, can't remember), I found out that China was building a new coal plant every week or something such, and my intuitive response was "Oh, so they got infinite coal or what? Won't that be a tough and costly transition when they finally run out?" and I guess this answers that
They're so desperate for coal they're one of the world's only users of brown coal, which is far more toxic, less efficient, and harder to transport. I could be wrong but I don't think the US ever even used the stuff to any real degree, even when coal was THE source of energy
@@Project2013B similar to the US, who also have massive stores of coal left even as coal use is rapidly tapering off. I don't know about Canada but I know the US still has massive deposits of the highest quality types of coal whereas China exhausting their supplies of high quality coal long ago.
6:26 It's inaccurate to say that Beijing doesn't regulate domestic coal prices. The National Development and Reform Commission (NDRC) regularly summons leaders of coal mining companies and electricity corporations to "negotiate" a fair coal price. The price is not fixed but doesn't fluctuate as much as the international market.

One of them - the first - is in Brazil and connects Itaipu to São Paulo state. The DC power lines are also useful to insulate the grid's parts so a disturbance on one part won't propagate to other parts. Brazil's DC line has other reasons: Itaipu was built on the border of Brazil and Paraguay and, at the time, there was a decision to set up half of the generators in 60Hz and half in 50Hz. Brazil buys the 50Hz produced for Paraguay - retifies it at Itaipu and alternates it near São Paulo city. For those who don't know, Itaipu was, until the Three Gorge Hydro Power Plant was built, the largest in the world.

A DC power line is a TERRIBLE idea. The reason you use AC is that the current alternates so the power line does not get HOT. When a powerline gets HOT, your efficiency of transferring power does DOWN, and you get sizeable voltage drops.
@@Project2013B HVDC is a new thing for long lines because it has smaller losses compare to our common AC lines. You're also incorrect as to why we use AC for transmission lines currently, nothing to do with heat/temperature but with power losses in long distances and more materials required for the cables.
We're building a new house for our family - here in Brazil we use masonry. The walls that will receive direct sunlight will be made of solid ceramic bricks while the others will use the hollow ones. Thick walls make for more expensive foundations and costs more but in the long run makes for a more comfortable and more energy efficient house. That's way, btw, the Empire State Building is the more energy efficient building in NY - the walls are made of stone.
An average person can't afford one. People want to build a house and decorate it with their savings as soon as possible. Get some bricks , cement and sand and build one. For heat? Get an AC , it's the cheaper option. I believe when the rich start shifting towards using mud walls and other things for building houses, it will gain an aspirational value. It will take a decade or two for that to happen.
I agree, but i think it comes down to cost in north america. Brick takes longer to build, can't be built below -5C, costs more to transport....etc while there is a full industry behind delivering standard sized, lightweight treated wood. So foundations are concrete, houses are wood. Also labor costs being so high here, it makes sense to use the faster build material
Great video, you should look at the electricity problem in South Africa. Currently the power goes out for 4 hours a day which has happened consistently for over a decade now with almost no exceptions. The electricity market in South Africa is a complete monopoly with only one government owned business providing electricity to the entire country. The company is called eskom and has proved to be extremely useless. Due to this constant power outages in South Africa, it’s caused their economy to suffer drastically with one article I read even saying it causes South Africa to be 50% less attractive to foreign investors and companies due to the lack of electricity.
@@kennethisaac233 absolutely. They’ve been trying to do that for a few years now but there’s so many laws not allowing for privatization, plus the government wants to keep it a monopoly since it allows for more corruption.
All those jobs are great. I know so many young guys who do something like that for a decade while learning all manner of things and who eventually start their own businesses with what they learned. The overlap in skills is large.

Another downside to relying so heavily on coal is that it’s not very adaptable. The grid’s demand is constantly fluctuating and utilities have to match the demand rather accurately or they risk either brownout or surge. This means you have to have a segment of your generation capacity devoted to matching the ebbs and flows of the grid. This is pretty easy in the US as this job is assigned to natural gas turbines. Regulating the generation of a turbine is a simple matter of restricting how much gas flows into the turbine. If more generation is needed, a gas turbine can go from cold to spin up and synced with the grid in about a half an hour. For coal, it’s not so simple. For a coal plant to heat up takes hours and regulating using a coal plant is highly inefficient. It isn’t a matter of throwing more coal on the pile. Generally, if you want to close regulate with a coal plant you have to throttle the turbine, which is less adaptive and still uses the same amount of coal as going full blast. Utility providers are much like farmers, using an almanac of previous years to predict the power peaks based on time of year, temperature, weather, etc, but even with the best predictions, grid providers can still be surprised. The US is fundamentally better equipped to deal with these fluctuations because the grid is built around fluid adaptability
@@lolwutasddfdfk first off, grid availability is based off transmission and distribution, not generation. Second off, the main reason china has the much shinier and fancier distribution infrastructure is because they got into the game much later. The US signed the rural electrification act in 1936 and within the decade every American citizen had access to reliable power. China has only recently started pushing for countrywide electrification with reforms in 1994. Even still, there are decent portions of western China, especially in areas with high percentages of Uyghurs and other ethnic minorities that simply do not have consumer access to power. It’s also worth noting that one of the main struggles with modernizing the US grid is property rights. Most of the land in the US is already developed and the owners of that land have the right to refuse the construction of utility infrastructure such as new high voltage power lines. In China, the party has much more power to completely ignore the protests of the people and build whatever is easiest. Finally, get off your high horse, there are still lines in use in certain parts of southern China that date back to the early 1900s. If we’d be able to look forward a hundred years, I’m quite certain China’s electrical infrastructure would be in equally dire need of modernization as the US’s is now. That is assuming the world hasn’t been destroyed by then
You obviously know something about power grids, so it baffles me why you would talk as if China only uses coal for power. Even in the video, it says China generates about 65% of its power from coal, so isn't it obvious that China would use coal as a baseline, and have all sorts of other power to handle the fluctuations? It's not like China doesn't have natural gas, or nuclear, solar, wind & hydro.
Sounds like you know a thing or two how utilities think. As a nuclear engineer works in the energy industry (NUCL safety analysis), I’d love to pick your brain on how the current system needs adapted to better work for a solely nuclear and renewables (just considering hydro/solar/wind here) based grid. (Primarily how peaking will be handled)
@@MrLando1996 I think I get it now. Both you and the other dude seem to focus on how a single source of power generation would handle different circumstances, maybe that's how power grids work in the US, separately and privately. However, the power grid in China works differently. The entire grid is owned by two companies that are both state-owned, they both own a huge variety of power plants, ranging from coal to gas, hydro, solar, nuclear, etc. They also built a variety of power preservation stations ranging from battery to water pumps. So what they'll do is keep coal and probably nuclear plants running all the time, and have the rest adjust to fluctuations. As for why such a mighty solution seemed to be causing blackouts this year, it's mainly because the water bureau usually lowers the water levels of all the dams before every summer to prepare for the flood season, and this year they were expecting huge floods so they did their job a little too good. Later it turned out that this summer was very dry and extremely hot, leaving hydro unable to provide as the residents were demanding more. It's like a perfect storm situation.
I thought I read somewhere that China had plans to drastically expand it's nuclear energy capabilities; I'm surprised there wasn't much discussion about that.
It is true, China developed a new type of nuclear reactor that is smaller, safer and generates little radioactive waste and over 200 of them are being developed and built with most coming online in the next decade. This new reactor is also currently being built for the Belt & Road countries. When it comes to China, Wendover Productions tend to pick data that matches its narrative so anything that does not fit is not included.
@@rcbrascan lol, you also cherry picking your data. Remember when China claim they pioneering green energy with their big solar farm? That's gone now Reversing deserts? That's also failed.
China does plan to drastically expand its nuclear energy, but building nuclear power plants is very tricky. Old technologies require nuclear power plants to be near a large body of water for cooling, which limits the locations, and they take a long time to build. So China is also trying newer technologies which still require a lot of testing. For example, it's testing Thorium Molten Salt reactors, which is an entire other branch of technology compared to uranium, so large-scale commercial deployment is only expected in 2030 (but the hope is that if it works, it can be mass-produced).
12:20 This is the reason why price caps need to be handled with care. The power plant owners are smart and shut down production when coal prices rose. This is one of the reasons why price caps often lead to shortages.
@@haplon33 it already pretty much is in China, and if they wanted to, they could bring the power authorities under direct government control easily, and yet they don’t.
The correct solution is for the government to cover the increase in coal cost temporarily until coal stabilises again This is just proof that nationalising a company while still running it as a profit oriented company is nonsense If China had fully nationalised their power industry they would have zero problems right now and their economy would be stronger
It's hard for modern Americans to imagine there was a time when an air conditioner in an automobile was an option...an option most people passed on (the technology has advanced considerably, so it's complicated, but still).
As someone who studies economic development, it seems there are many things modern Americans don't realize their grandparents lived without.. I think the average American doesn't even know that universal electrification (meaning 99% of the populace has direct access to electricity) wasn't complete until the 1970s. There were still several million Americans who didn't have home power during the "golden 50s" we always rave about
Yes, I remember my 1st new car - Honda Accord 1991 model, air conditioning was optional and my 1st car , 1985 Renault lee car did not have air conditioning.
Every car I had , had AC and I'm a boomer. In 2020 AC played out in my Nissan Rogue OMG I was living in Apple Valley California in the high desert. Cost 800$ for another one. I was upset about the amount but I realize how blessed I was to have the money. Thank God.
@@hiphipjorge5755the 50s were golden... I dont see how a small percentage of homes not having electricity somehow changes that. Anyone who lives near a city has power then.
You don't want high voltage lines working at 100%. If lines are at their limit shifting load and maintaining them becomes very difficult. Especially in the hotter months.
Also the electricity running through the lines generates heat and in hotter climates, those lines can get extremely hot. Further disrupting power distribution.
@@TheKlaun9 Saying 60% is low is like saying the highway was badly planned because it's not congested. Fun fact, sun only shines for half the day, if the line is designed to carry solar, it will always average to around 60%.
we can't ignore that China has the biggest population in the world, which is literally more than other the continent's risdents in Europe North America Australia combined
Nuclear is the cleanest, the strongest and the safest if managed by competent people who run it properly with proper security measures and personnel. Especially if we use plutonium. We just need good public perception and proper political support with good investment capital and awareness.
Its clean but also expensive. China does not want to invest up front, same problem like the renewables, the initial investment is to expensive for them. They would rather have short term gains then long term.
People also don't think about how much the LED bulb and the CFL before it led to plateauing energy in advanced countries.

And at night the lights that are typically on in my house equal maybe 10-12 watts. Even our biggest TV uses just 52 watts. My last CRT TV used over 200 watts. Computers and game consoles are the only remaining energy suck beyond cooling or heating your house. Or charging your car...

Nuclear is both the past and future of power generation. See info about coal exhaust vs total EVER nuclear waste. It's crazy. And it's important to remember that the nuclear accidents that have happened were the result of severe design flaws and/or negligence. We can figure out what to do with (nearly) indestructible crates of nuclear waste later, but this needs to be solved now.
What about external factors like plane accidents, extreme natural disasters, wars and terrorism? Unthinkable now in most places but you never know how everything will be in 50 years.
My problem with nuclear is that it comes with a CIA. A few guys with guns are not enough to protect these plants. With nuclear follows mass surveillance, aka the giving up of privacy. Meaning these massive infringes that happen today will never be stopped when they have the nuclear protection card. It's not only about getting rid of peoples' right to privacy, but that it also follows with societal control. You are likely aware that their interests (of the ruling class) rarely align with yours. Which means that power will be used against your interests, especially when it is clear where neoliberalism is headed. If you think the instability today is bad, it's going to get far worse in the upcoming decades.
People are working on it, the French are betting their entire future on that. But it's actually not that easy - Nuclear power is way too expensive at the moment and it's such a slow process to build new plants. The issues shown in this video are immediate and so is the global crisis this belongs to. We need something now, figure out nuclear power later ... or build a time machine
I dont understand, why Germany is shutting down their remaining nuclear plants. They will burn coal instead - how is that better? Untill we find a new source of energy or a way how to storage renewable energy, we need nuclear as a transitory energy source. With the climate change becoming worse every year, there is not really any other option.
@@vince6473 we already dealt with this. In the US there is reinforced concrete protecting nuclear plants so powerful, they slammer a fighter jet into it at high speed, and the jet crumbled.
The ac problem can be found in most places as well, Africa, India, Australia... For me it's something that should be the world top priority and get better research funding from everyone just like EV had in recent times. Hopefully we will have a new innovation in these coming years,
The problem is that ACs are already super efficient heat pumps, depending on the quality of the model. The 'fix action' is better insulation for the buildings being cooled. Considering all the tofudreg buildings in China, the buildings probably have an insulation value of 10-20% of an average 'western' building. That exacerbates the power draw to keep buildings cool vastly more than the AC itself.
@@Konsaki Id also think of better flow too? not a buiilder, but as a home buyer in the south I looked for a house that has good flow in case (as it has happpened) I have no ac.
australias problem is unique. we produce TOO MUCH solar power during the day, leading to grid instability, then it all shuts off at the same time, then people get home and turn on their AC and start draining the grid, causing more instability. if we didnt have solar, the AC issue would be easy to manage. storage will be incredibly important in the very near future for australia. i wont be surprised if we end up having the highest energy storage per capita in the world once grid-compatible sodium ion batteries become mass produced.
@@cetriyasArtnComicsChannel good flow doesn't do nearly as much as good insulation. If you have poor insulation good flow just means the building loses heat just as quickly as it spreads, so it could even do a building worse

China's coal may be plentiful but is of low quality which is ok for power production (albeit not as efficient as good quality coal). The coal Australia exported was of high quality metallurgical coal used for coking for blast furnaces used for steelmaking (the ore Australia also provides but not sanctioned) therefore essential for their economy, when China put sanctions on many Australian products there was always another country willing to purchase our goods especially coal
Their manufacturing sections relied on the Australian coal and are geared to such, thus they were in strife when it wasn't available. My understanding is that India buying the Aussie coal and then China is buying it from India at a much price thna previously

Brazil has also experienced two powerful droughts, which affected our energy production because more than 50% of it comes from hydroelectric power plants. The solution the government found was to encourage the construction of new natural gas thermoelectric plants, which raised controversy because of the high costs and pollution. On the other hand, wind power production is growing at a fast pace and is already the third largest source of energy.
Natural gas plants, properly regulated, dont produce that much air quality pollution. The CO2 emissions are moderate (~600kg per MW/h?). The claim that is made is that it is forest clearing and ranching that have been the main cause of the drying of Brazil and the droughts. Irrigation as well? Dams and changes to the water flows might have had an impact as well. It is a big hungry population of 200+ million people. The government will need to try and do major land works to try and improve yield and productivity. And people there will need to adapt to the changing conditions, very little of it can actually be % attributed to global climate change. Most of it will be regional factors.
People figured this out over 100 years ago. My house is 120 years old in Australia, it's not fancy but it's got 12 foot high ceilings. In summer it's so cool inside wouldn't even think about air conditioning because all the heat rises to the ceiling and vents let the hot air out. Shame about winter though it's a bit cold.
I know! Though nuclear IS less cost competitive than renewables. I still think its the ideal base load solution, but its cost inefficiency has always been what made it hard to produce.
@@johnnybraccia452 Sure. After all, fission nuclear power plants, including the ones in China, have a better safety record than all other sources of energy.

@@baronvonlimbourgh1716 It wasn't without economic consequence for Europe. Some industries have scaled back production to reduce gas consumption, and in long term that is not sustainable. Those industries will leave Europe, probably for the US, and very likely, once they do leave, they will never come back. Putin is not doing Europe a favour, Europe is still suffering. It's also had consequences for environmental goals, coal plants have been producing more and planned closures have been put on hold. On the plus side, Germany has postponed planned closures of nuclear power stations and there's renewed interest across europe in nuclear energy. I know that's probably not a good thing in your books but it is in mine!
Maybe adding nuclear power would help a lot, its kinda the highest output power tech around and its damn clean too, building lead-lined bunkers to store the waste that comes out every couple years when they need their fuel rods replaced is not that bad, we know how to seal the stuff away and we know how to reuse it now too for both space applications with RTGs or ultra-long-life low-power installations for experiments and/or sensors for weather and how much cosmic radiation is hitting us from both the sun (which is the main driver of the climate I mean sunlight is kinda responsible for about 108 PW of light and heat globally while mankind consumes just around 31 TW) and the rest of the galaxy, and nuclear can throttle slowly up and down with oil and coal based plants providing ride-through for those times that solar, wind and perhaps hydro inevitably go up and down, since batteries powering the grid is kinda not good for the environment at all, unless we figure out a way to make massive amounts of sodium-based batteries and/or really good gigantic supercaps that don't use loads of rare earth metals that are really expensive and also really dirty to mine and process, like cobalt and lithium are. Basically, nuclear good, renewable good but not something we can fully rely upon, fusion nowhere near viable yet (no exploding a tiny capsule and getting more energy out than the lasers is not viable that's an explosion not sustained fusion), and oil and coal power can be the thing that patches over the gaps in throttling nuclear up and down to match renewable ebbs and flows. In fact, those ultra-long-life sensor installations can be used to calculate when to throttle up and down nuclear plants depending on weather around solar and wind installations, know when wind will pick up or more sun will come through the clouds so it can be throttled down in time with the rising generation from renewable, or throttle back up when conditions deteriorate and sunlight wanes and wind weakens. The theory is simple, implementation will be a real pain in man's collective asses, it'll sure make a lot of jobs for people to find work in and it'll keep us going until the time if/when fusion finally becomes viable, in several decades or so at least methinks.
Way simpler solution that is fool proof, reduce demand, reduce user count. As the saying goes reduce, reuse and recycle, clear out useless players first, do this in indirect ways that make it seem like it is their own decision to rage quit in one way or another, after all were in the civilized 21st century, useless will be defined as anyone who can be replaced with a machine to do the task they filled, and the player is no longer able to adapt a new strategy to be productive. Reuse, these are all the players who are of slightly higher quality than the previous group and are able to adapt to fit into a new piece of the system that rewards them a smaller share of resources, this is done through monetary inflation so nominally this new task appears to pay them more which is why they take it in reality it pays less and they consume less doing x task. Finally recycle, with the resources being freed up from the first 2 groups all of that can be recycled to the people, who actually matter and are smart enough to use them productively to build a better future.
Nuke-powered power stations in an autocratic country are dangerous... the world has seen one Chornobyl disaster... I don't think the world is ready for another disaster.
The best way to store energy from renewables has been with us since the 50's or so it's called hydropower and we can use the extra energy created by cheap renewables to lift water or anything actually and drop it when it's needed as it falls it powers a turbine. Coal is already obsolete, have you not noticed that some of the biggest miners are already leaving it and going into renewables, even our mineral smelters and furnaces are already heading that way calling it 'green steal' not blue steal (as the coal industry wants). We simply don't have the time to wait for new Nuclear to come online and no-one wants it or it's radioactive rubbish near them, despite what it's promotors will tell you about their safety they are not!
Interesting. The domestic supply issues could point to why they're reaching out and investing in opening mines in other countries (like canada for example)
As a Chinese, in the last 15 years I have rarely heard of power shortages, and I have never seen a blackout, not even once. In the hottest part of summer, the air conditioning is always on where I live and work.
But where do you live though? A tier one city gets electricity priority so if theres a shortage it is the smaller and poorer cities that get the short end of the stick
I live in a relatively rich city, but I do remember the shortage of electricity at that time because I did business and remembered many factories being influenced at that time. Many suppliers could not offer goods on time that year.
That's cause Cali has forced population diversity whereas China is actively getting rid of ethnic diversity. Ethnic unity is strength and China is set to run over the US given enough time because of it
@1pars142 wrong. “As of 2020, no UHVDC line (≥ 800 kV) exists in Europe or North America.” - Wikipedia, under HV DC. @los caobos sequera the other (3) are 1 in India & 2 in Brazil.
My hometown is a small city in China's Gansu province, the least developed region of China, which has been growing like crazy since 2014, a city of 300,000 people with 100,000 cars, where summers are getting hotter and hotter
Your presentation style is captivating and the team who put Wendover content together are top notch? Although we should point out China is manufacturing the worlds goods and if they don't burn coal to do it then other countries would need to. No countries energy mix has enough eco friendly options such as modern nuclear plants to deliver the products we humans have become accustomed to. Globally we need to consume less and recycle more. I practice what I preach.
You'd need to recycle at all before you can recycle more. Depending on which Western country you live in you likely don't recycle at all, even if you think you do. China does most of the worlds recycling, the US would literally ship them its recycling to do. It is extremely low wage work. Will Americans pick through trash?
This is why industrial production needs to be distributed to each country, and each country must bear its own share of carbon emissions if it wants to develop its economy.
Chinese policy of pushing down the cost of inputs like labour, energy and complete disregard for the environment caused it to be the manufacturing powerhouse, not because other countries were looking to export their pollution. Companies don't care what generated the power as long as it is cheap. China chose this path of growth at any cost.
@@Millionsofpeas Not anymore, after China enacted the national sword policy they can't dump it in China anymore so advanced recycling is picking up in America too.
I don't know where you got your data, but the data I got was that air conditioning consumes 40% of total power generation during the hottest months of the summer in some areas, and 30% on average nationally, yet that's just during the hottest months. China's combined wind and solar power installations will surpass coal power installations for the first time this year. You need to update your data. The U.S. consumes five times as much electricity per capita as the Chinese, and given the U.S.'s two withdrawals from the Global Carbon Reduction Agreement, you'd do well to spotlight U.S. behavior.

Bear in mind, vast arrays of solar panels have to be kept clean on a schedule, otherwise their efficiency goes down due to sunblocking particles (natural dust, sand, bird stuff etc). And they have a life span of 20 years ish. So it's not a completely free solution.
I'm not so confident they're really cheaper when all costs are considered. The US, for example, regulates the price at which solar and wind can be bought and sold and the industry is heavily subsidized.
Solar is awesome for sail boats, tiny homes and homesteads. They are a waste otherwise. We can't even recycle the panels. They cost nearly 5 times to break down then the recycled material is worth.
Almost all solar panels and batteries are made in China. So they should be able to build them for even cheaper than what they sell for. Thus is a clear admission that solar and wind on large scale does not work and certainly does not work for a giant industrial plant.
@@hstapes Oh it's most definately more expensive that what is claimed. Solar/wind does not replace conventional power sources, they reduce fuel consumption. You still have to keep those power plants up and running or you'll end up with blackouts whenever the wind slows or the sun goes down. Effectively we're paying the cost of wind and solar on top of the cost of keeping the conventional power plants running minus some fuel consumption.
around 5:00 you say that upfront cost of KW of coal is lower - this is not true actually - not anymore at least. it is more predictable power source for sure, but at least for AC - this doesn't matter as the peak solar power production obviously corresponds to peak AC usage.
Not once have you mentioned how big China's population plays in how quickly China rose, but also in relation to how much they need compared to the USA & many other countries besides India.
If we ignore the fact that wind and solar energy extreme fluctuation(because you know...sun does not always shine and the wind does not always blow) then maybe it may be competitive.
Does anyone have a map of energy cost to maintain ideal indoor temperature? The discussion of air conditioning in China and the US at the start got me thinking, it would be interesting to see how this plays out over the whole world taking cold countries into account also. Basically I want to see where would be cheapest and most expensive.
You'd be stunned in disbelief if you saw how many ACs in China run full-blast beside wide open windows. (conversely full-blast heaters near wide-open windows in the winter months). I am, in no ways, joking. You'd be just astonished if you saw this.
@@hhvhhvcz If you go to hot countries and look at traditional buildings, you notice two things, thick walls and small windows, that are usually shuttered during the day. It's usually so dark inside that lights have to be on all the time people are awake. Problem is that is the antithesis to the desire for natural light and outdoor views many modern buildings incorporate. You can make building insulation as thick as you like, but it can all be for nothing if the owners want a panoramic window.
Offshore wind was not mentioned. As a source, it is much closer than the inland regions and is reliable, which is due to the permanence of winds offshore.
Probably interferes too much with shipping lanes, which are also critical to China's economic security. Plus there's the yearly typhoons, which very few turbines could withstand.
A definite masterpiece of overview of the problem. Anyone working on power electronics knows that demand for Chinese State Grid and EV companies are insanely high. I appreciate the mention of UHVDC transmission, an infrastructure that the US can only imagine being built. And if you work with automotive you should know that the amount of push to go from no reg to a euro 6 equivalent and potentially leading the way soon with NS7 is quite impressive. I think the world needs to thank Chinese people for their sacrifice. I’m not chinese but lived in China and from the way people get to work to how people set their AC is much more sustainable then the west. For example: I ride the metro to work. It’s electric and one might say, oh it comes from coal. Sure. But emissions of mass transportation is much lower per head per km travelled. My didi/gaode/uber ride is electric and i ride my ebikes for nearby shopping where as I used my F150 back home to go get a six pack to Walmart driving at least 10 miles round trip vs buying in one of the convenience store walking. My Chinese office set their AC temperature at 26C/78-80F on a 40C/104F weather outside meanwhile i set my personal office at 20C. Chinese colleagues then use their tumbler to fill in hot water meanwhile I drink a refrigerated plastic bottle of water. One thing china can learn is usage of plastics though.
If you are comparing to the US, then yes, China is much better. But the US has the highest electricity consumption per capita and the highest CO2 emissions per capita, not an example for anything really. Compared to France, Netherlands, Sweden, Norway, Denmark and other developed countries, China doesn't look so great.
In the 1970s, the US started mandating things like sulfur scrubbers on power plant smoke stacks. Does anyone know what China does to mitigate pollutants?
New power plants already installed those things. The more important reason cause pollution are the centralised heating stations which burn coals built decades ago. Every cities in north China have couple of them and they are old and not profitable (it’s more like public facilities). That’s why most of the haze happened in the winter and north China.
Don't you love how people in power manipulate words and math? "China says it is lowering emissions, looking at 2005 levels, by 65%." Not 2022? o_O What reality is this? (15:55)
0:45 Canada's energy usage per capita is higher the the US. And since they have a larger GDP than Russia (who you included on that graph) they should take the top spot for major economies ranked by energy use per capita.
Russian rubles are extremely devalued in international currency markets. In real terms, the Canadian economy is less than half the Russian one and doesn't make the top 10.
@Bill Kong first off it is not undervalued. The exodus of western compaies combined with a shrinking economy and population gives it its current value. Also the ranking is from before it got heavily devalued.
I enjoy your channel and your deep dives on subjects. I wish you could do one on how much raw material it will take to hit all these green projects. I don't think we could mine enough fast enough or if proven finds are sufficient.
Energy storage will be the single biggest issue for all of it, followed closely by the pricing structures. Solar generation is cheap. Solar energy storage? Not so much. It's part of why California's grid is so messed up, paired with mandatory solar on new construction, net metering, and no time-of-day credit adjustments. Generate enough power from solar to hit net negative? Great. Your utility has to buy it from you when it's practically worthless and apply that credit to you during evening hours, right at peak pricing. Natural gas and (coal-intensive) imports cover that peak, which can be four times the middle of the day net demand. Most electricity storage these days happens through pumped hydro (at least in the US). It works well for what we've got now, but backing up solar power that way would require dozens of Hoover Dam sized facilities. Grid battery capacity is slowly increasing, but the technology is nowhere near what's needed right now. All the lithium in the world will barely cover the estimated US *Electric Vehicle* demand, let alone residential and grid demands here and everywhere else. There have been breakthroughs recently in Sodium as well as Aluminum batteries, but it'll probably be at least 5-10 years before those hit widespread availability. We'll get there, but it'll take a while.
@@EmptyZoo393 I dont understand why Germany is shutting down their remaining nuclear plants. They will burn coal instead - how is that better? Untill we find a new source of energy or a way how to storage renewable energy, we need nuclear as a transitory energy source. With the climate change becoming worse every year, there is not really any other option.
@@gorkyd7912 Exactly, if you remove knowledge of something, clearly that something stops existing, like the fibrous growths the shots cause clearly don't exist just like how if you miss the ground you can fly :P
Nuclear is key. China is building reactors at a faster pace than anywhere else but they need to do it even more, as only nuclear energy can provide the constant high energy output required by industrial applications.
Nuclear has the major issue of NIMBY. It's quite bad in the even today very sparsely populated US. In China, where any populated province has a population density comparable to western Europe, the kinds of distances efficient for nuclear just can't work
it's also worth pointing out that the regions with the most renewable energy potential, the west and inner mongolia, are the ones with political tension and separatist movements, esp xinjiang and tibet in the west. don't know how that's going to work out in their favor if they do become key energy producing regions for the rest of the country. :/ i really liked this video, it was insightful, loved the clip of the two uncles playing chess in the back of their truck.
The medieval slaughterers Dalai Lama and terrorists from ETIM (East Turkmenistan Islamic Movement, financed by the NED) have no support in the wide majority of the PR China. 99.9% of the population have no interest in getting balkanized by the USA, as they did in neighboring Afghanistan, where people are eating dirt mixed with oil for "western democracy". Regarding the fact, that the number of 25 million Uighur-citizens (who are by 96% able to write and speak their dialect teached in schools, with 10 times the number of mosques - 25.000 alone in Xinjiang - than in the USA) has doubled in a few decades, makes all the stupid cultural genocide allegations look what they are - idiotic and ridiculous sinophobia - with the single "source" anti-emancipation and anti-gay Adrian Zenz, "on a mission led by God, to destroy communist China" (in his own words).
Of course there will be polictcal tension because the US Goverment had payed billions of dollers each year for deliberate sabotage in those areas. Just in 2020 USA had paided at least 10 Million USD(more than 20% of Tuvalu's GDP) just for organzed sabotage in China. And they even made a chart for their money usage, which shows that the US goverment don't even care about the fact, that they are activly disturbing another country's inner politic.
15:28 Idk. I guess anything is possible, but based on just the examples you listed, I would lean toward a qualified answer. That answer would be, "Sure, they can still do it, but what would be the costs, both financial and the other costs (such as human rights, the well-being of the Chinese people, etc.)?"
You should do a video on South Africa, our electricity provider Eskom has normalised what they call "Loadshedding" and all parts of the country have rolling blackouts for years but it is getting worse...
Why didn't you consider population of USA and China? China with 1.5B people is expected to have 5 times more electricity consumption when compared with usa with just 300M people. As you said in the video, because majority power consumption is domestic, population measurement makes more sense than gdp one.
This is intentional as the average viewer (who is from the US) doesn't understand the per capita concept. This channel is propaganda for americans. This channel says what the average american wants to hear.
Norway used to have an electricity cost of 3 cents per kwh. Now the price is hovering at about 30 cents per kwh. Luckily 90% of everything above 7 cents per kwh is subsidised which makes the true price about 10 cents per kwh. And we are still complaining. Now that i learnd that the price in china is 8 cents per kwh and the fact that that is way below world average baffled me. Which also serves to prove that without a doubt the superior way of generating electricity is with hydroelectric plants.
Another reason why renewable energy sources are not being adopted is because they are substantially less reliable than fuel based energies. Another consideration is the substantial land-use of solar power, plus the near impossibility of recycling the components of solar panels. Both wind and solar power also have a negative affect on certain types of wildlife that isn't often talked about.
Yes, these are the things nobody likes to talk about. The media has people believing it is as simple as flipping a switch and making the change from fuel based to renewable energy and it just isn't that simple. One example recently was the mass failure of wind turbines in Texas. As it stands currently, these sources are fine for supplemental and standby energy, but are not anywhere near ready to be the main supply.
The video production is excellent, thank you. Regarding energy issues, here are a few points that were not mentioned in the video: 1. Nuclear power: Firstly, the proportion of nuclear power in China is currently low at 5%, but there is still significant room for growth. China currently has 55 nuclear power plants in operation, with 46 more planned. There are also 22 plants under construction, with a goal to increase nuclear power capacity by 6-8 units annually. The mass development of third-generation reactors cannot be rushed due to the large consumption of nuclear fuel. Research is also being conducted on six different fourth-generation nuclear power designs, with four of them already having experimental and demonstration reactors connected to the grid. China is in a leading position in this field. 2. Renewable energy generation: The main challenge lies in the weather-dependent and intermittent nature of renewable energy sources. Efforts are being made to address issues related to transmission networks and intermittent power supply through energy storage. Recently, commercial projects for hydrogen production from offshore wind power and solar power have been implemented. The construction of an ultra-high voltage transmission network, which is considered infrastructure, is well underway. China is also in a leading position in this field. Therefore, improvements are expected in the future. 3. Coal-fired power generation and mining: Although China is increasing the proportion of nuclear and renewable energy, coal-fired power generation still plays a significant role. China is a global leader in ultra-supercritical power generation, even reaching the "ultra-ultra-supercritical" level, with a 7% higher efficiency, 15% reduction in coal consumption, and 10% reduction in carbon dioxide emissions compared to subcritical units. In terms of coal mining, small mines have been closed, and large mines have achieved a high level of digitization and intelligence. The increase in coal-fired power generation is mainly due to the seasonal power shortages that occurred in the past two years, which raised concerns. It is necessary to appropriately increase coal-fired power generation in suitable locations. When facing seasonal or unexpected power shortages, the coal-fired power supply can be activated or increased dynamically to ensure power supply and, more importantly, the safety of the power system. Based on the determination and actual progress in increasing the proportion of nuclear and renewable energy generation, there is no need to add coal-fired power generation, except in areas where additional capacity is needed. In conclusion, with a comprehensive understanding, it is clear that there are existing problems that have been identified and are being addressed. Once thorium-based molten salt reactors are successfully commercialized, it will be possible to provide each medium-sized or larger city with small-scale, water-independent, and higher safety standard nuclear power units. As for nuclear fusion, although China has made some leading experimental achievements, it is still premature to draw conclusions. However, considering China's track record, significant progress can be expected. 视频制作很不错，感谢。 关于能源问题，补充几点此片没有提到的： 1. 核电：首先中国的核电占比5%很低，还有较大的空间，已有55座，计划中46座，在建的有22座，正在以每年6-8台核电机组的速度增加。 如果现在大规模发展第三代堆，每年的核燃料消耗量太大，所以不能急。 第四代核电有六种方案都在研究，其中四种已经分别建设实验堆、示范堆且发电并网。 这方面处于领先地位。 2. 新能源发电：主要问题是受天气影响大、不稳定，需要配合储能和远距离输送措施。 前些年有很多太阳能发电、风电浪费掉，目前主要是在解决输电网络、储能解决间歇性问题。最近海上风力发电制氢、太阳能发电制氢已陆续投入商用。特高压输电网络属于基础设施建设，主干已经基本成形，还在陆续建设。这方面处于领先地位。 所以，接下来会好很多。 3. 燃煤发电和采矿：虽然中国在增加核电、新能源发电的比例。 但中国在超临界发电方面全球领先，属于“超超临界”的水平，较亚临界机组效率高约7%，单位煤耗、二氧化碳排放可减少15%及10%。而煤矿方面，关停小煤矿，大型煤矿数字化、智能化水平非常高。 那么，为何煤电有所增加？ 前两年发生的季节性电力短缺引起了重视。 需要在一些合适的位置适当增加部分煤电，当发生季节性、突发性事件导致的电力短缺时，可以启动和增加煤电供应来动态调配，不仅仅保障供电，更重要的是保障电力系统安全。 可见，基于提高核电、新能源发电占比的决心和实际进展，在需要增补的地方之外，没必要新增煤电。 所以，全面了解之下得出的结论：存在问题，已经发现，正在解决。 尤其钍基熔盐堆一旦成功商业化运营，将来可以为每个中型以上城市配置一到两个小型的、不依赖水、更高安全标准的核电机组。 至于核聚变，虽然中国有部分领先的实验性成果，但还不敢下结论。但以中国一向的风格，估计偏离不大。

One of them - the first - is in Brazil and connects Itaipu to São Paulo state. The DC power lines are also useful to insulate the grid's parts so a disturbance on one part won't propagate to other parts. Brazil's DC line has other reasons: Itaipu was built on the border of Brazil and Paraguay and, at the time, there was a decision to set up half of the generators in 60Hz and half in 50Hz. Brazil buys the 50Hz produced for Paraguay - retifies it at Itaipu and alternates it near São Paulo city.
For those who don't know, Itaipu was, until the Three Gorge Hydro Power Plant was built, the largest in the world.

A DC power line is a TERRIBLE idea. The reason you use AC is that the current alternates so the power line does not get HOT. When a powerline gets HOT, your efficiency of transferring power does DOWN, and you get sizeable voltage drops.
@@Project2013B HVDC is a new thing for long lines because it has smaller losses compare to our common AC lines. You're also incorrect as to why we use AC for transmission lines currently, nothing to do with heat/temperature but with power losses in long distances and more materials required for the cables.
We're building a new house for our family - here in Brazil we use masonry. The walls that will receive direct sunlight will be made of solid ceramic bricks while the others will use the hollow ones. Thick walls make for more expensive foundations and costs more but in the long run makes for a more comfortable and more energy efficient house. That's way, btw, the Empire State Building is the more energy efficient building in NY - the walls are made of stone.
LOL! Love it. "Here in Brazil, we use masonry." You know, that little trick humans have known about for around 8,000 years? ;-)
An average person can't afford one. People want to build a house and decorate it with their savings as soon as possible.
Get some bricks , cement and sand and build one. For heat? Get an AC , it's the cheaper option.
I believe when the rich start shifting towards using mud walls and other things for building houses, it will gain an aspirational value. It will take a decade or two for that to happen.
I am going for masonry House for myself in India.
With lots of trees and Water harvesting.
I agree, but i think it comes down to cost in north america. Brick takes longer to build, can't be built below -5C, costs more to transport....etc while there is a full industry behind delivering standard sized, lightweight treated wood. So foundations are concrete, houses are wood. Also labor costs being so high here, it makes sense to use the faster build material
I highly doubt the Empire State Building is the most energy efficient in nyc
Great video, you should look at the electricity problem in South Africa. Currently the power goes out for 4 hours a day which has happened consistently for over a decade now with almost no exceptions. The electricity market in South Africa is a complete monopoly with only one government owned business providing electricity to the entire country. The company is called eskom and has proved to be extremely useless. Due to this constant power outages in South Africa, it’s caused their economy to suffer drastically with one article I read even saying it causes South Africa to be 50% less attractive to foreign investors and companies due to the lack of electricity.
Do you think they should privatize it all? I think if they could seed control to private firms while maintaining ownership.
@@kennethisaac233 absolutely. They’ve been trying to do that for a few years now but there’s so many laws not allowing for privatization, plus the government wants to keep it a monopoly since it allows for more corruption.

Another downside to relying so heavily on coal is that it’s not very adaptable. The grid’s demand is constantly fluctuating and utilities have to match the demand rather accurately or they risk either brownout or surge. This means you have to have a segment of your generation capacity devoted to matching the ebbs and flows of the grid. This is pretty easy in the US as this job is assigned to natural gas turbines. Regulating the generation of a turbine is a simple matter of restricting how much gas flows into the turbine. If more generation is needed, a gas turbine can go from cold to spin up and synced with the grid in about a half an hour. For coal, it’s not so simple. For a coal plant to heat up takes hours and regulating using a coal plant is highly inefficient. It isn’t a matter of throwing more coal on the pile. Generally, if you want to close regulate with a coal plant you have to throttle the turbine, which is less adaptive and still uses the same amount of coal as going full blast. Utility providers are much like farmers, using an almanac of previous years to predict the power peaks based on time of year, temperature, weather, etc, but even with the best predictions, grid providers can still be surprised. The US is fundamentally better equipped to deal with these fluctuations because the grid is built around fluid adaptability
Lol, all the more shows how much of a failure the US is, when it has worse power grid availability than China
@@lolwutasddfdfk first off, grid availability is based off transmission and distribution, not generation. Second off, the main reason china has the much shinier and fancier distribution infrastructure is because they got into the game much later. The US signed the rural electrification act in 1936 and within the decade every American citizen had access to reliable power. China has only recently started pushing for countrywide electrification with reforms in 1994. Even still, there are decent portions of western China, especially in areas with high percentages of Uyghurs and other ethnic minorities that simply do not have consumer access to power. It’s also worth noting that one of the main struggles with modernizing the US grid is property rights. Most of the land in the US is already developed and the owners of that land have the right to refuse the construction of utility infrastructure such as new high voltage power lines. In China, the party has much more power to completely ignore the protests of the people and build whatever is easiest. Finally, get off your high horse, there are still lines in use in certain parts of southern China that date back to the early 1900s. If we’d be able to look forward a hundred years, I’m quite certain China’s electrical infrastructure would be in equally dire need of modernization as the US’s is now. That is assuming the world hasn’t been destroyed by then
You obviously know something about power grids, so it baffles me why you would talk as if China only uses coal for power. Even in the video, it says China generates about 65% of its power from coal, so isn't it obvious that China would use coal as a baseline, and have all sorts of other power to handle the fluctuations? It's not like China doesn't have natural gas, or nuclear, solar, wind & hydro.
Sounds like you know a thing or two how utilities think. As a nuclear engineer works in the energy industry (NUCL safety analysis), I’d love to pick your brain on how the current system needs adapted to better work for a solely nuclear and renewables (just considering hydro/solar/wind here) based grid. (Primarily how peaking will be handled)
@@MrLando1996 I think I get it now. Both you and the other dude seem to focus on how a single source of power generation would handle different circumstances, maybe that's how power grids work in the US, separately and privately. However, the power grid in China works differently. The entire grid is owned by two companies that are both state-owned, they both own a huge variety of power plants, ranging from coal to gas, hydro, solar, nuclear, etc. They also built a variety of power preservation stations ranging from battery to water pumps. So what they'll do is keep coal and probably nuclear plants running all the time, and have the rest adjust to fluctuations.
As for why such a mighty solution seemed to be causing blackouts this year, it's mainly because the water bureau usually lowers the water levels of all the dams before every summer to prepare for the flood season, and this year they were expecting huge floods so they did their job a little too good. Later it turned out that this summer was very dry and extremely hot, leaving hydro unable to provide as the residents were demanding more. It's like a perfect storm situation.
I thought I read somewhere that China had plans to drastically expand it's nuclear energy capabilities; I'm surprised there wasn't much discussion about that.
It is true, China developed a new type of nuclear reactor that is smaller, safer and generates little radioactive waste and over 200 of them are being developed and built with most coming online in the next decade. This new reactor is also currently being built for the Belt & Road countries.
When it comes to China, Wendover Productions tend to pick data that matches its narrative so anything that does not fit is not included.
Yep. This video was well presented, but factually a complete fail. Nuclear is China's solution to energy production, greenhouse gases, and pollution.
@@rcbrascan lol, you also cherry picking your data. Remember when China claim they pioneering green energy with their big solar farm? That's gone now
Reversing deserts? That's also failed.
China bad so...he won't show it
China does plan to drastically expand its nuclear energy, but building nuclear power plants is very tricky. Old technologies require nuclear power plants to be near a large body of water for cooling, which limits the locations, and they take a long time to build. So China is also trying newer technologies which still require a lot of testing. For example, it's testing Thorium Molten Salt reactors, which is an entire other branch of technology compared to uranium, so large-scale commercial deployment is only expected in 2030 (but the hope is that if it works, it can be mass-produced).
12:20 This is the reason why price caps need to be handled with care. The power plant owners are smart and shut down production when coal prices rose. This is one of the reasons why price caps often lead to shortages.
almost like it should just be nationalized as a national security issue or something
That's why private energy is a silly idea.
@@haplon33 it already pretty much is in China, and if they wanted to, they could bring the power authorities under direct government control easily, and yet they don’t.
The correct solution is for the government to cover the increase in coal cost temporarily until coal stabilises again
This is just proof that nationalising a company while still running it as a profit oriented company is nonsense
If China had fully nationalised their power industry they would have zero problems right now and their economy would be stronger
So THIS is why in Sim City games, nuclear is so expensive and coal and oil are so cheap. =P (4:57)
It's hard for modern Americans to imagine there was a time when an air conditioner in an automobile was an option...an option most people passed on (the technology has advanced considerably, so it's complicated, but still).

I think the average American doesn't even know that universal electrification (meaning 99% of the populace has direct access to electricity) wasn't complete until the 1970s. There were still several million Americans who didn't have home power during the "golden 50s" we always rave about

You don't want high voltage lines working at 100%. If lines are at their limit shifting load and maintaining them becomes very difficult. Especially in the hotter months.
I have no idea about line maintenance, but the video implied 60% was low. Is that incorrect? I don't remember it suggesting 100%. Please let me know
Also the electricity running through the lines generates heat and in hotter climates, those lines can get extremely hot. Further disrupting power distribution.
@@TheKlaun9 Usually you have transmission lines running in parallel for redundancy. If one line goes down, you want the active lines not overloaded

I've heard Thorium is also a good idea.
Its clean but also expensive. China does not want to invest up front, same problem like the renewables, the initial investment is to expensive for them. They would rather have short term gains then long term.
People also don't think about how much the LED bulb and the CFL before it led to plateauing energy in advanced countries. Every light bulb in my house is LED and every single one could be ion and it might be 100 watts total. That's crazy. We aren't that far removed from 60 watts being the standard for a single bulb. And at night the lights that are typically on in my house equal maybe 10-12 watts. Even our biggest TV uses just 52 watts. My last CRT TV used over 200 watts. Computers and game consoles are the only remaining energy suck beyond cooling or heating your house. Or charging your car...

Nuclear is both the past and future of power generation. See info about coal exhaust vs total EVER nuclear waste. It's crazy. And it's important to remember that the nuclear accidents that have happened were the result of severe design flaws and/or negligence. We can figure out what to do with (nearly) indestructible crates of nuclear waste later, but this needs to be solved now.
What about external factors like plane accidents, extreme natural disasters, wars and terrorism? Unthinkable now in most places but you never know how everything will be in 50 years.
My problem with nuclear is that it comes with a CIA. A few guys with guns are not enough to protect these plants. With nuclear follows mass surveillance, aka the giving up of privacy. Meaning these massive infringes that happen today will never be stopped when they have the nuclear protection card.
It's not only about getting rid of peoples' right to privacy, but that it also follows with societal control. You are likely aware that their interests (of the ruling class) rarely align with yours. Which means that power will be used against your interests, especially when it is clear where neoliberalism is headed. If you think the instability today is bad, it's going to get far worse in the upcoming decades.
People are working on it, the French are betting their entire future on that. But it's actually not that easy - Nuclear power is way too expensive at the moment and it's such a slow process to build new plants. The issues shown in this video are immediate and so is the global crisis this belongs to. We need something now, figure out nuclear power later ... or build a time machine
I dont understand, why Germany is shutting down their remaining nuclear plants. They will burn coal instead - how is that better? Untill we find a new source of energy or a way how to storage renewable energy, we need nuclear as a transitory energy source. With the climate change becoming worse every year, there is not really any other option.

The ac problem can be found in most places as well, Africa, India, Australia... For me it's something that should be the world top priority and get better research funding from everyone just like EV had in recent times. Hopefully we will have a new innovation in these coming years,
The problem is that ACs are already super efficient heat pumps, depending on the quality of the model.
The 'fix action' is better insulation for the buildings being cooled.
Considering all the tofudreg buildings in China, the buildings probably have an insulation value of 10-20% of an average 'western' building. That exacerbates the power draw to keep buildings cool vastly more than the AC itself.
@@Konsaki Id also think of better flow too? not a buiilder, but as a home buyer in the south I looked for a house that has good flow in case (as it has happpened) I have no ac.
australias problem is unique. we produce TOO MUCH solar power during the day, leading to grid instability, then it all shuts off at the same time, then people get home and turn on their AC and start draining the grid, causing more instability. if we didnt have solar, the AC issue would be easy to manage. storage will be incredibly important in the very near future for australia. i wont be surprised if we end up having the highest energy storage per capita in the world once grid-compatible sodium ion batteries become mass produced.
@@cetriyasArtnComicsChannel good flow doesn't do nearly as much as good insulation. If you have poor insulation good flow just means the building loses heat just as quickly as it spreads, so it could even do a building worse

All they have to do is build a billion bicycles attached to a battery and a power cord to add the energy to the electric grid. +P
China's coal may be plentiful but is of low quality which is ok for power production (albeit not as efficient as good quality coal). The coal Australia exported was of high quality metallurgical coal used for coking for blast furnaces used for steelmaking (the ore Australia also provides but not sanctioned) therefore essential for their economy, when China put sanctions on many Australian products there was always another country willing to purchase our goods especially coal
Their manufacturing sections relied on the Australian coal and are geared to such, thus they were in strife when it wasn't available. My understanding is that India buying the Aussie coal and then China is buying it from India at a much price thna previously

Brazil has also experienced two powerful droughts, which affected our energy production because more than 50% of it comes from hydroelectric power plants. The solution the government found was to encourage the construction of new natural gas thermoelectric plants, which raised controversy because of the high costs and pollution. On the other hand, wind power production is growing at a fast pace and is already the third largest source of energy.
Natural Gas is non-polluting. OTOH, windmills are highly polluting when they reach the end of their useful life and need to be disposed of.
Natural gas plants, properly regulated, dont produce that much air quality pollution. The CO2 emissions are moderate (~600kg per MW/h?).
The claim that is made is that it is forest clearing and ranching that have been the main cause of the drying of Brazil and the droughts. Irrigation as well? Dams and changes to the water flows might have had an impact as well.
It is a big hungry population of 200+ million people.

5:26 thats not the only reason. there's also the fact that solar takes up 10 times more space, is unreliable and requires tons of precious medals
4:15, Europe switching to natural gas was probs their best and worst idea
It was a good idea. It got us over the hump when renewables where not yet viable.
Now putin is doing us pretty much a favor, sending the entire eu scrambling to accelerate every renewables project on the books while at the same time getting rid of much of the energy waste in the system.
The amount gas usage dropped over the span of a couple of months was crazy. It reflects how much waste there was in the system, the things that could be cut easilly without much investment or concequences. But simply wasn't because of people being lazy or complacent.
And now gas prices are down again. They even went negative again for a bit last week and all the available storage is filled to the brim as well so nobody needs to be cold this winter afteral.
@@baronvonlimbourgh1716 Renewables are useless without natural gas peakers to turn their unreliable power into reliable power. Germany found this out the hard way. But the rest of Europe seems to still not have gotten the memo. The real purpose of renewables is to greenwash natural gas. That's why Germany's grid is so dirty even after $500b in renewables being deployed.

@@baronvonlimbourgh1716 It wasn't without economic consequence for Europe. Some industries have scaled back production to reduce gas consumption, and in long term that is not sustainable. Those industries will leave Europe, probably for the US, and very likely, once they do leave, they will never come back. Putin is not doing Europe a favour, Europe is still suffering. It's also had consequences for environmental goals, coal plants have been producing more and planned closures have been put on hold.
On the plus side, Germany has postponed planned closures of nuclear power stations and there's renewed interest across europe in nuclear energy. I know that's probably not a good thing in your books but it is in mine!
@@Croz89 lol 👍.
Maybe adding nuclear power would help a lot, its kinda the highest output power tech around and its damn clean too, building lead-lined bunkers to store the waste that comes out every couple years when they need their fuel rods replaced is not that bad, we know how to seal the stuff away and we know how to reuse it now too for both space applications with RTGs or ultra-long-life low-power installations for experiments and/or sensors for weather and how much cosmic radiation is hitting us from both the sun (which is the main driver of the climate I mean sunlight is kinda responsible for about 108 PW of light and heat globally while mankind consumes just around 31 TW) and the rest of the galaxy, and nuclear can throttle slowly up and down with oil and coal based plants providing ride-through for those times that solar, wind and perhaps hydro inevitably go up and down, since batteries powering the grid is kinda not good for the environment at all, unless we figure out a way to make massive amounts of sodium-based batteries and/or really good gigantic supercaps that don't use loads of rare earth metals that are really expensive and also really dirty to mine and process, like cobalt and lithium are. Basically, nuclear good, renewable good but not something we can fully rely upon, fusion nowhere near viable yet (no exploding a tiny capsule and getting more energy out than the lasers is not viable that's an explosion not sustained fusion), and oil and coal power can be the thing that patches over the gaps in throttling nuclear up and down to match renewable ebbs and flows. In fact, those ultra-long-life sensor installations can be used to calculate when to throttle up and down nuclear plants depending on weather around solar and wind installations, know when wind will pick up or more sun will come through the clouds so it can be throttled down in time with the rising generation from renewable, or throttle back up when conditions deteriorate and sunlight wanes and wind weakens. The theory is simple, implementation will be a real pain in man's collective asses, it'll sure make a lot of jobs for people to find work in and it'll keep us going until the time if/when fusion finally becomes viable, in several decades or so at least methinks.
Way simpler solution that is fool proof, reduce demand, reduce user count. As the saying goes reduce, reuse and recycle, clear out useless players first, do this in indirect ways that make it seem like it is their own decision to rage quit in one way or another, after all were in the civilized 21st century, useless will be defined as anyone who can be replaced with a machine to do the task they filled, and the player is no longer able to adapt a new strategy to be productive. Reuse, these are all the players who are of slightly higher quality than the previous group and are able to adapt to fit into a new piece of the system that rewards them a smaller share of resources, this is done through monetary inflation so nominally this new task appears to pay them more which is why they take it in reality it pays less and they consume less doing x task. Finally recycle, with the resources being freed up from the first 2 groups all of that can be recycled to the people, who actually matter and are smart enough to use them productively to build a better future.
Nuke-powered power stations in an autocratic country are dangerous... the world has seen one Chornobyl disaster... I don't think the world is ready for another disaster.
@@devin19222 honestly, your plan sounds amazing, start by reducing yourself
The best way to store energy from renewables has been with us since the 50's or so it's called hydropower and we can use the extra energy created by cheap renewables to lift water or anything actually and drop it when it's needed as it falls it powers a turbine. Coal is already obsolete, have you not noticed that some of the biggest miners are already leaving it and going into renewables, even our mineral smelters and furnaces are already heading that way calling it 'green steal' not blue steal (as the coal industry wants). We simply don't have the time to wait for new Nuclear to come online and no-one wants it or it's radioactive rubbish near them, despite what it's promotors will tell you about their safety they are not!
Not an issue - China's population is about to plummet == demographics
Interesting. The domestic supply issues could point to why they're reaching out and investing in opening mines in other countries (like canada for example)
Yeah China already began to source coal in other countries
As a Chinese, in the last 15 years I have rarely heard of power shortages, and I have never seen a blackout, not even once. In the hottest part of summer, the air conditioning is always on where I live and work.

I swear to God, I was sure that I was watching an Economics Explained video, until he said Wendover at the end.
Lmao a few of these channels do blend together
Your presentation style is captivating and the team who put Wendover content together are top notch? Although we should point out China is manufacturing the worlds goods and if they don't burn coal to do it then other countries would need to. No countries energy mix has enough eco friendly options such as modern nuclear plants to deliver the products we humans have become accustomed to. Globally we need to consume less and recycle more. I practice what I preach.
You'd need to recycle at all before you can recycle more. Depending on which Western country you live in you likely don't recycle at all, even if you think you do. China does most of the worlds recycling, the US would literally ship them its recycling to do. It is extremely low wage work. Will Americans pick through trash?
This is why industrial production needs to be distributed to each country, and each country must bear its own share of carbon emissions if it wants to develop its economy.
Consuming less is orders of magnitude above recycling more. It’s incredibly more efficient to not use plastic in the first place than to recycle it.
Chinese policy of pushing down the cost of inputs like labour, energy and complete disregard for the environment caused it to be the manufacturing powerhouse, not because other countries were looking to export their pollution. Companies don't care what generated the power as long as it is cheap. China chose this path of growth at any cost.
@@Millionsofpeas Not anymore, after China enacted the national sword policy they can't dump it in China anymore so advanced recycling is picking up in America too.
I don't know where you got your data, but the data I got was that air conditioning consumes 40% of total power generation during the hottest months of the summer in some areas, and 30% on average nationally, yet that's just during the hottest months. China's combined wind and solar power installations will surpass coal power installations for the first time this year. You need to update your data. The U.S. consumes five times as much electricity per capita as the Chinese, and given the U.S.'s two withdrawals from the Global Carbon Reduction Agreement, you'd do well to spotlight U.S. behavior.

Bear in mind, vast arrays of solar panels have to be kept clean on a schedule, otherwise their efficiency goes down due to sunblocking particles (natural dust, sand, bird stuff etc).
And they have a life span of 20 years ish.
So it's not a completely free solution.
I'm not so confident they're really cheaper when all costs are considered. The US, for example, regulates the price at which solar and wind can be bought and sold and the industry is heavily subsidized.
It's called kicking the can down the road.
Solar is awesome for sail boats, tiny homes and homesteads. They are a waste otherwise. We can't even recycle the panels. They cost nearly 5 times to break down then the recycled material is worth.
Almost all solar panels and batteries are made in China. So they should be able to build them for even cheaper than what they sell for. Thus is a clear admission that solar and wind on large scale does not work and certainly does not work for a giant industrial plant.
@@hstapes Oh it's most definately more expensive that what is claimed. Solar/wind does not replace conventional power sources, they reduce fuel consumption. You still have to keep those power plants up and running or you'll end up with blackouts whenever the wind slows or the sun goes down. Effectively we're paying the cost of wind and solar on top of the cost of keeping the conventional power plants running minus some fuel consumption.
What I've learned from this video is that I am so not the typical Wendover viewer.
around 5:00 you say that upfront cost of KW of coal is lower - this is not true actually - not anymore at least. it is more predictable power source for sure, but at least for AC - this doesn't matter as the peak solar power production obviously corresponds to peak AC usage.
Not once have you mentioned how big China's population plays in how quickly China rose, but also in relation to how much they need compared to the USA & many other countries besides India.

Honestly pretty straight forward solutions to the air conditioning problem.
If we ignore the fact that wind and solar energy extreme fluctuation(because you know...sun does not always shine and the wind does not always blow) then maybe it may be competitive.

A definite masterpiece of overview of the problem.
Anyone working on power electronics knows that demand for Chinese State Grid and EV companies are insanely high. I appreciate the mention of UHVDC transmission, an infrastructure that the US can only imagine being built. And if you work with automotive you should know that the amount of push to go from no reg to a euro 6 equivalent and potentially leading the way soon with NS7 is quite impressive.
I think the world needs to thank Chinese people for their sacrifice. I’m not chinese but lived in China and from the way people get to work to how people set their AC is much more sustainable then the west. For example:
I ride the metro to work. It’s electric and one might say, oh it comes from coal. Sure. But emissions of mass transportation is much lower per head per km travelled. My didi/gaode/uber ride is electric and i ride my ebikes for nearby shopping where as I used my F150 back home to go get a six pack to Walmart driving at least 10 miles round trip vs buying in one of the convenience store walking. My Chinese office set their AC temperature at 26C/78-80F on a 40C/104F weather outside meanwhile i set my personal office at 20C. Chinese colleagues then use their tumbler to fill in hot water meanwhile I drink a refrigerated plastic bottle of water. One thing china can learn is usage of plastics though.
If you are comparing to the US, then yes, China is much better.
But the US has the highest electricity consumption per capita and the highest CO2 emissions per capita, not an example for anything really.
Compared to France, Netherlands, Sweden, Norway, Denmark and other developed countries, China doesn't look so great.

Every cities in north China have couple of them and they are old and not profitable (it’s more like public facilities). That’s why most of the haze happened in the winter and north China.

The quantities needed are nearly invisibly small if you stack them next to a year's worth of coal. Don't worry about it.
@@gregvanpaassen You are correct. But it is not a question of quantity. As Glen A suggests, it is a question of availability.
Energy storage will be the single biggest issue for all of it, followed closely by the pricing structures. Solar generation is cheap. Solar energy storage? Not so much. It's part of why California's grid is so messed up, paired with mandatory solar on new construction, net metering, and no time-of-day credit adjustments.
Generate enough power from solar to hit net negative? Great. Your utility has to buy it from you when it's practically worthless and apply that credit to you during evening hours, right at peak pricing. Natural gas and (coal-intensive) imports cover that peak, which can be four times the middle of the day net demand.
Most electricity storage these days happens through pumped hydro (at least in the US). It works well for what we've got now, but backing up solar power that way would require dozens of Hoover Dam sized facilities.
Grid battery capacity is slowly increasing, but the technology is nowhere near what's needed right now. All the lithium in the world will barely cover the estimated US *Electric Vehicle* demand, let alone residential and grid demands here and everywhere else. There have been breakthroughs recently in Sodium as well as Aluminum batteries, but it'll probably be at least 5-10 years before those hit widespread availability.
We'll get there, but it'll take a while.
@@EmptyZoo393 I dont understand why Germany is shutting down their remaining nuclear plants. They will burn coal instead - how is that better?

Right now, where I live, it is 86ºF and 80% humidity. So air cons are a great benefit, but they usually have to run all day.
Nuclear is key. China is building reactors at a faster pace than anywhere else but they need to do it even more, as only nuclear energy can provide the constant high energy output required by industrial applications.
Nuclear has the major issue of NIMBY. It's quite bad in the even today very sparsely populated US. In China, where any populated province has a population density comparable to western Europe, the kinds of distances efficient for nuclear just can't work
it's also worth pointing out that the regions with the most renewable energy potential, the west and inner mongolia, are the ones with political tension and separatist movements, esp xinjiang and tibet in the west. don't know how that's going to work out in their favor if they do become key energy producing regions for the rest of the country. :/

Regarding the fact, that the number of 25 million Uighur-citizens (who are by 96% able to write and speak their dialect teached in schools, with 10 times the number of mosques - 25.000 alone in Xinjiang - than in the USA) has doubled in a few decades, makes all the stupid cultural genocide allegations look what they are - idiotic and ridiculous sinophobia - with the single "source" anti-emancipation and anti-gay Adrian Zenz, "on a mission led by God, to destroy communist China" (in his own words).

As you said in the video, because majority power consumption is domestic, population measurement makes more sense than gdp one.
This is intentional as the average viewer (who is from the US) doesn't understand the per capita concept. This channel is propaganda for americans. This channel says what the average american wants to hear.
Norway used to have an electricity cost of 3 cents per kwh. Now the price is hovering at about 30 cents per kwh. Luckily 90% of everything above 7 cents per kwh is subsidised which makes the true price about 10 cents per kwh. And we are still complaining. Now that i learnd that the price in china is 8 cents per kwh and the fact that that is way below world average baffled me. Which also serves to prove that without a doubt the superior way of generating electricity is with hydroelectric plants.

Another reason why renewable energy sources are not being adopted is because they are substantially less reliable than fuel based energies. Another consideration is the substantial land-use of solar power, plus the near impossibility of recycling the components of solar panels. Both wind and solar power also have a negative affect on certain types of wildlife that isn't often talked about.
Yes, these are the things nobody likes to talk about. The media has people believing it is as simple as flipping a switch and making the change from fuel based to renewable energy and it just isn't that simple. One example recently was the mass failure of wind turbines in Texas. As it stands currently, these sources are fine for supplemental and standby energy, but are not anywhere near ready to be the main supply.
The video production is excellent, thank you.
Regarding energy issues, here are a few points that were not mentioned in the video:
1. Nuclear power: Firstly, the proportion of nuclear power in China is currently low at 5%, but there is still significant room for growth. China currently has 55 nuclear power plants in operation, with 46 more planned. There are also 22 plants under construction, with a goal to increase nuclear power capacity by 6-8 units annually. The mass development of third-generation reactors cannot be rushed due to the large consumption of nuclear fuel. Research is also being conducted on six different fourth-generation nuclear power designs, with four of them already having experimental and demonstration reactors connected to the grid. China is in a leading position in this field.
2. Renewable energy generation: The main challenge lies in the weather-dependent and intermittent nature of renewable energy sources. Efforts are being made to address issues related to transmission networks and intermittent power supply through energy storage. Recently, commercial projects for hydrogen production from offshore wind power and solar power have been implemented. The construction of an ultra-high voltage transmission network, which is considered infrastructure, is well underway. China is also in a leading position in this field. Therefore, improvements are expected in the future.
3. Coal-fired power generation and mining: Although China is increasing the proportion of nuclear and renewable energy, coal-fired power generation still plays a significant role. China is a global leader in ultra-supercritical power generation, even reaching the "ultra-ultra-supercritical" level, with a 7% higher efficiency, 15% reduction in coal consumption, and 10% reduction in carbon dioxide emissions compared to subcritical units. In terms of coal mining, small mines have been closed, and large mines have achieved a high level of digitization and intelligence. The increase in coal-fired power generation is mainly due to the seasonal power shortages that occurred in the past two years, which raised concerns. It is necessary to appropriately increase coal-fired power generation in suitable locations. When facing seasonal or unexpected power shortages, the coal-fired power supply can be activated or increased dynamically to ensure power supply and, more importantly, the safety of the power system.
Based on the determination and actual progress in increasing the proportion of nuclear and renewable energy generation, there is no need to add coal-fired power generation, except in areas where additional capacity is needed.
In conclusion, with a comprehensive understanding, it is clear that there are existing problems that have been identified and are being addressed. Once thorium-based molten salt reactors are successfully commercialized, it will be possible to provide each medium-sized or larger city with small-scale, water-independent, and higher safety standard nuclear power units. As for nuclear fusion, although China has made some leading experimental achievements, it is still premature to draw conclusions. However, considering China's track record, significant progress can be expected.
视频制作很不错，感谢。
关于能源问题，补充几点此片没有提到的：
1. 核电：首先中国的核电占比5%很低，还有较大的空间，已有55座，计划中46座，在建的有22座，正在以每年6-8台核电机组的速度增加。
如果现在大规模发展第三代堆，每年的核燃料消耗量太大，所以不能急。
第四代核电有六种方案都在研究，其中四种已经分别建设实验堆、示范堆且发电并网。
这方面处于领先地位。
2. 新能源发电：主要问题是受天气影响大、不稳定，需要配合储能和远距离输送措施。
前些年有很多太阳能发电、风电浪费掉，目前主要是在解决输电网络、储能解决间歇性问题。最近海上风力发电制氢、太阳能发电制氢已陆续投入商用。特高压输电网络属于基础设施建设，主干已经基本成形，还在陆续建设。这方面处于领先地位。
所以，接下来会好很多。
3. 燃煤发电和采矿：虽然中国在增加核电、新能源发电的比例。
但中国在超临界发电方面全球领先，属于“超超临界”的水平，较亚临界机组效率高约7%，单位煤耗、二氧化碳排放可减少15%及10%。而煤矿方面，关停小煤矿，大型煤矿数字化、智能化水平非常高。
那么，为何煤电有所增加？
前两年发生的季节性电力短缺引起了重视。
需要在一些合适的位置适当增加部分煤电，当发生季节性、突发性事件导致的电力短缺时，可以启动和增加煤电供应来动态调配，不仅仅保障供电，更重要的是保障电力系统安全。
可见，基于提高核电、新能源发电占比的决心和实际进展，在需要增补的地方之外，没必要新增煤电。
所以，全面了解之下得出的结论：存在问题，已经发现，正在解决。
尤其钍基熔盐堆一旦成功商业化运营，将来可以为每个中型以上城市配置一到两个小型的、不依赖水、更高安全标准的核电机组。
至于核聚变，虽然中国有部分领先的实验性成果，但还不敢下结论。但以中国一向的风格，估计偏离不大。
The irony seen here of being sponsored by the likes of HelloFresh is actually quite astounding to me.
Why? Is there something up with HelloFresh i dont get?,
@@mithim99 I'm certainly no expert on the topic, but in my view, all those online-driven services, like HelloFresh, @m@z¤n, uber, etc. are perhaps one of the driving forces which led, or at least contribute, to the crisis he's describing in the video. But I could be mistaken.
@@rigelb9025 they cause extreme gdp growth in China?
I grew up in Shanghai and when I was a kid I did have frequent power cuts, especially in the summer, and had to light candles to do my homework. Now it's completely different, China has 30% of the world's power generation capacity, but some media are still stuck in the same place as 20 years ago!😮😮
I think the per capita is the most important measure, since china's population is significantly larger than any other country's.
China almost has the same population as India. I don't really think excuses should be made when the country is drivem by coal for the majority of it's electricity production, and is currently making more coal power plants .
@@LuKing2 Maybe you should ask all the nations that produce more CO2 emission per capita than India or China, what excuses do they have? I don't think China rather burn coal if they have a better alternative.
@@chl8487 most of them are already working pretty hard on lowering their admissions, at the very least the majority of rich western countries aren't opening new coal power plants like China is
