This talk will challenge the popular perception that Battery Electric Vehicles (BEVs) are environmentally friendly, and will argue that we are inappropriately rushing the market introduction of these vehicles. BEVs are commonly sold under the guise of being ‘Zero Emissions,’ an assertion that is not true by any definition. Brake pads produce emissions, as do
tires and even interiors under sunlight. The electricity that powers BEVs is generated by power plants, 64% of which burn fossil fuels in the U.S.-fossil fuels that contribute to greenhouse gas emissions and global warming. Even more importantly, there are significant CO2 emissions
created during the manufacture of the battery pack, meaning that in order to offset the carbon created during the production process, a BEV must drive 40,000 - 100,000 miles before being environmentally comparable to a gasoline-powered vehicle. Hybrid vehicles, on the other hand,
which combine much smaller batteries with efficient internal combustion engines, have been shown to be a much better option for lowering global CO2. Unfortunately, they do not receive the same marketable ‘kudos’ or policy backing as full BEVs. We are headed down the wrong path by
rolling out BEVs before making the manufacturing and electricity generation CO2 neutral. Dr. Graham Conway is a Principal Engineer in the Automotive Division at Southwest Research Institute. For the last ten years he has been immersed in evaluating automotive technologies and consulting for car companies and suppliers. This gives him unique insights and perspectives on the industry. He is passionate about making vehicles more efficient to ensure the future of the planet and has a message to share about some common misconceptions about electric and non-electric vehicles.

Don't forget. It makes more sense from a green perspective to keep your old car running and well-maintained as long as you can. There are significant environmental costs to both manufacturing a new automobile and adding your old car to the ever-growing collective junk heap.
That's not necessarily true. It depends on how much you drive, the mileage your old car gets, and what you plan to replace it with.
I had a 1973 Plymouth Satellite that I kept 19 years and 236,000 miles; and later a 2000 Ford Taurus that I kept twelve years and 150,000 miles. I'm doing my part...
my 30yo Honda Civic is still fun to drive and reliable - my main problem (apart from the lack of airbags - I'm a safe driver) is the cost of registration and third-party insurance - nearly $1000pa for a car I only drove about 1000km last year
so local share cars I can rent for $10/hour look relatively attractive - except I had a huge fight over a $1500 charge for a fake/scam 'repair' from a major car rental firm - I got it refunded after 3 months of 20 emails and threats but I lost a lotta sleep - so that's put me off those kinda businesses
This argument is mostly used to encourage inaction.
The environmental impacts caused by each problem are not equal.
The pressing issue is atmospheric carbon. There is also an issue with waste recycling, landfill usage, etc but those are not as dangerous to the future of the planet even in the long term.
Don't take a 1 year old car off the road to replace it with electric. But don't drive it for 20 year either. We need most of the world to be on electric cars in about 20 years and for the grid to be mostly renewable in 30
@@NotMyActualName_ you ought to take a look at the total percentage of carbon emissions that come from passenger vehicles.
It takes a lot of energy to produce these vehicles, so hold onto your vehicles longer, your clothes, phones etc longer. However, big companies don’t want this to happen.
Unfortunately, under this current administration household budgets are stretched or worse. The objective of converting America to EV's and other alternatives is Biden's catch 22. With spending power gone, most people will reuse the old worn out vehicles and goods that are now less environmentally friendly out of necessity.
Making quality products that last long time & keeping them is big part of solution that is ignored. Better public transportation would also make bigger difference than EV cars.
The video is only about vehicles.
So right! Recycle, re-use and repurpose!
It's called "planned obsolescence" or pure greed...... they don't want you to own anything, they want your very existence to be a service they can charge you for......
With so called renewable energy, emissions for the production of solar panels (and the recycling of failed ones) also needs to be taken into account. As a mechanic I do service hybrid cars also and so many of them can't even reverse out of the service bay without the petrol engine starting and when test driving the petrol engine spends more time running than you think.
Absolutely correct. Solar panels are made from toxic metals (the mining of which is monopolized by the Chinese), and end up in landfills once they go kaput, because they can't be recycled. The same is true for EV batteries. The people touting batteries and solar panels act like these things just magically appear out of nowhere and don't have any harmful costs/externalities. Green energy is dangerous fraud.
i too service and own a hybrid vehicle and yes some instance mine does start when its been sat in the 'READY' mode or a while... i think my petrol engine kicks in at 20mph but i would sooner have that than a all electric .... even the battery tech on mine is more stable that of the lithium cells
Building wind and solar does produce lots of emissions also.
It doenst produce anything the vast amounts of CO2 and CH4 that increase and maintain the greenhouse effect
Old saying: "There is no such thing as a free lunch."
its only gonna be temporary though because once the required amount is built, no more will be needed so no more being built and no more emissions made from making them
@@grommitt1385Not true, solar panels and turbine blades wear out and need to be replaced regularly. Turbine blades in particular are literally just buried in massive landfills as they can't be feasibly recycled. Still better than a coal power plant? Surely, but nothing is perfect.
Do solar panels have to be produced every day that they're being used, like oil does? No. Try to actually use your brain.
I'd like to see him go into the carbon footprint of the production and lifespan of solar and wind powered sources. never mind the recyclability of them or lack of.
They have made great strides. Lots of articles with updates.
Yes, without doing that analysis, the conclusions of his video do not make sense, I am afraid.
Every year, I see more wind farms and solar panel fields going up. They are eating up agricultural land and wildlife habitat. All this in an effort to meet an insatiable demand for electric power. Most of the solution needs to occur on the demand side. How much energy do we really need? No one talks very much about Fusion power, but truly it could be mankind's salvation. It could lead the way to viable fuel cells, ability to generate freshwater from salt, weaning the global shipping industry from carbon fuels.
the future is nuclear
@@colin591 the only future in fact but people are too scared because of a few incredibly rare incidents.
He makes great points! BUT "renewable sources" of energy still produce a HUGE about of waste and are damaging to the environment. If we would encourage Nuclear power as the main source of power, the amount of effect on the environment would be by far the lowest.
HILARIOUS! As though creating renewable energy doesn't create C02. I'll just throw 2 fun facts (2 of MANY) about wind turbines. 1) Each turbine requires 750 YARDS of concrete! Hmmm... wonder what they did to conjure that up? 2) Each turbine blade has a serviceable life of about 15 years, after which they are removed, then BURIED (they're made of carbon-fiber and are not recyclable) in giant landfills where earthmoving machines carve out shallow graves for them - they are about 120 feet long.
But the same leftists that were screaming about nuclear in the 70's will start screaming again. How do you and Greta handle that?
In my VAST expertise! LOL. Maybe, we could actually get people in Congress that truly understand Neuclear Power and how Clean, Reliable, and Safe it is. Then use it as a "middle" ground between the left and the right????
Whether there truly is global warming and IF it is truly influenced by "Man," no of that matters. We can't depend on fossil fuels forever. There is a limited amount. IF we start to build nuclear power plants again AND continue to use ALL sources of energy until the plants are up and running.....we could be truly "energy independent " (making the right happy) AND truly "Green" (once the vast majority of our power is nuclear) thus making the left happy.
It would be a WIN/WIN.
@@patrickf7182 The carbon payback time of a turbine is generally under a year and for solar cells it's generally less than 3 years. Solar cells have service guarantees starting at 20 years now and I would expect roughly the same from turbines. If a turbine does indeed fail after 15 years, that's still >15x carbon savings. Recycling them is indeed a problem but there is no silver bullet and companies are working on recycling the resins and fiberglass blades.
@@Arkir24 Nuclear Reactors can effectively run in perpetuity. 20 years is not a long time. Not only have companies complained that they didn't last as long as stated, they're going to be replacing them every day.
It is so wonderful to find someone that feels the same way about electric vehicles as I do...as a hotrodder I LOVE ELECTRIC CARS !!!! but there are many points against going full electric on a national or even world level that you addressed so wonderfully.
My only issue with your talk is the use of solar and wind generators...to go back to the pollution emissions you talked about in batteries the same can be said about solar and wind.
On a recent trip down to Texas I had the opportunity to see the wind farms across the nation being repaired/updated and the carbon footprint created by this exercise far outweighs the benefits to this endeavor.
As we see in today's news California is having an issue as to what to do with the outdated and burned out solar panels that contain toxic metals....they have driven out all recyclers able to deal with this and are now resorting to just burying them which will cause future ecological issues (liberal hypocrisy at it's finest I guess)
We should ask ' Why are the most efficient solar panels banned from being imported into the US?' but we are afraid of the answer.
Why is wind power pushed so hard when it shows it can not provide power equal to it's pollution defecate (that word is wrong but google correct can't fathom so...) ?
As I said...as a hotrodder I am all for electric vehicles....I have followed 'Gone Postal' , 'Killacycle' and many others and they are awesome !
I agree with everything you said...except...the solar and wind power point....Nuclear and Hydro are the only proven clean energy systems that we can rely on.
I'm totally with you on the nuclear side. And hydro too but that is more geography specific. In some places it can be virtually impact free on nature while in others it does cause harm.
@@chrisbauer1925 Unfortunately it is not that simple. I am a big fan of nuclear, but for most countries around the world it is not economically possible to go fully nuclear. France, the nuclear superpower, is facing a huge issue having outdated reactors long after the end of life cycle, that will be super expesive to replace/renew, and they might be possibly shut down in near future. Hydro, as you mentioned, can be a local ecological disaster, and also produces co2 and methane due to a large standing body of water with stuff rotting inside, but still, it is one of the cleanest.
Just saying that no solution is easy, and it will take time to mitigate the issues. We should focus on all aspects, not just one. Make solar less toxic, make wind more efficient, nuclear cheaper, use hydro where safe, live less wasteful lives, vote for environmentally aware parties...
Yeah the last two are actually the hardest to achieve
They cause a bigger carbon footprint print then a combustion engine
yes !!!
Great points but Conway works for Southwest Research Institute which does a lot of work with oil and gas and has many patents related to fossil fuels.
He claims that the average cumulative driving emissions for combustion non-hybrid is 30 tons. Over 180k miles that’s about 151g/co2 per mile. The official EPA emissions for a Toyota Camry non hybrid is about 280g/mile. For the hybrid variant about 170g/mile. He is showing data that is off by more than 80% compared to a sedan which isn’t even representative of what average people drive in the US. Take all the trucks and SUVs, the EPA estimates about 350-400g/mile for US average. That drastically changes his argument.
Great talk. He seemed to make the same mistake though: he didn’t draw the box around the solar panel or the wind turbines? Would be interesting to see the numbers for that.
Actually wind turbine never produce enough "green" electricity in it's life time to offset CO2 required to build the turbine at the first place
He tells us to view the EV as a whole yet he didn't account for Co2 emissions of processing a barrel of oil to gasoline. One barrel of oil to gas (42 gallons) produces 520 pounds of Co2 (237kg)
It is true to say that todays solar panels have a carbon footprint but as time goes by solar panels and wind etc will gradually replace all carbon emitting manufacturing processes, we have to start somewhere 🙂
@@daliborzak2485 Same thing with solar. Look into tellurium some time, and the whole mountainsides that China has to blow up to keep pace with the US' and Europe's demand for solar panels.
@@captainphoenix Stop cherry picking; stop with the false equivalency. Stop lying.
Total mining in the world will be drastically reduced as we switch to 100% renewable energy. The harm done by mining & other industrial processes would also be dramatically reduced by getting rid of capitalism & the Wetiko disease that causes it.
I'm in the renewable energy field and even that needs to be looked at. During construction and operation of a wind or solar farm, thousands of gallons of diesel are burned every day, not to mention the environmental impacts on tree clearing on a large scale. Plus the life cycle of wind turbines is usually 20-30 years and large components arrive on ships (which burn 2000 gal of heavy diesel per hour) and major components like the blades end up in landfills when the site is repowered as they are not recyclable. Nuclear is the best thing we have so far.
Oil production has all of the same problems without the benefit of resulting in carbon free energy.
Wind turbine blades only last 7 years, if that. The neseil which is the main component is 7 years. Depending on whether it's a 3-piece or a four-piece Tower each section is good for 20 years.
And one wind turbine produces barely enough to to power one home lol
@@NSWvet83 what kind of a home is using more than 6 million kwh in a year?
And is oil flying from the ground into the cars? It is shipped with millions of transportation in every possible form causing insane destruction. How many pumps, pipes, ships, trucks etc are built and used purely to transport oil? If we want to caunt in really everything (we must) the picture for oil will look much much worse. How many oil ship disasters have we seen? How many wars and kills for oil fields? I could list all the sh!t that comes with oil all day long..
"There are no solutions, only tradeoffs."
-Thomas Sowell
Even pretending like solar and wind is 0 CO2 should be subjected to the same analysis to come to the same conclusion, merely a trade off. It’s said the CO2 in the concrete foundation of the windmill off-sets it’s benefit. Also, the life span of solar and wind hardware is limited and solar being heavily dependent on batteries for it’s greatest utility. There is indeed only trade-offs and a bunch of salesmen in-charge of mystifying the truth.
Well, I like the sentiment, but Sowell is a crackpot when it comes to economics.

Like George Carlin said, "When the earth is ready, it will shake us off like fleas. Regardless of what we do to it".
He also said that humans could not impact the environment.. but i believe that was deeep satire.
@@hickstylezhis math could also be said to be satire.

no discussion on the AMOUNT of water needed to manufacture the components that end up in either vehicle. Fresh, potable water is a huge environmental aspect that needs to be taken into consideration.
@williamhamer How true. And it comes out wildly in favor of RE & EVs.
@@J4Zonian How does it favor EVs? From what I understand, just mining Lithium for the batteries requires a lot of water.
@@roykowalski4125 Everything humans do has effects. The harm done by fuels is so phenomenally, extraordinarily, tremendously huge, that RE & EVs are a tiny fraction of it, & get smaller as more RE & EVs are added to the grid & to manufacturing. ICEVs only get worse, as EROEI gets smaller & fuels get farther, deeper, scarcer, & more diffuse, which they’ve been doing for a while.
People need to stop paying attention to the insane right wing climate-denying delayalist & ARF (anti-renewable fanatic) blogs & the politicians & media they own. They’re lying to you.
@@J4Zonian And people need to do there own homework and really analyze the data rather than paying attention to left wing climate and renewable energy fanatics. Look at California and Germany for example. The cost of renewable energy sources has come down (solar panels, turbines) yet the cost of electricity keeps rising. How come no one is talking about how many years we went backwards in "harm done" during covid lockdowns world wide, no one was driving. Reason is because there was no significant change to talk about. How come when when climate fanatics say things like "The earth hasn't been this hot in 3,000 years" no one asks the reason the earth was this hot 3,000 years ago? The problem is people either go all in left or all in right and have done zero research or are have the data to take either position. Partisan politics has gotten to the point where even science will be on one side or the other. Researchers don't get funding unless they lie on one side or the other.
How do they do it in Saudi? Local municipalities will NEVER allow desalinization, because they want total control over water production, but you will never hear this on the news.
He was doing fine until he claimed that renewable electric energy sources (solar and wind) produce no CO2. He needs to include the CO2 produced during their manufacture and operation. Windmill blades are produced from composite materials in which most of the components are derived from petroleum.
True, but the total energy cost is still much less.
CO2 is not a pollutant and CO2 concentration is closer to plant starvation than over saturation.
Yes making them recyclable, right?
He also doesn't address what happens when there is no sun and wind? Neither has renewable energy come up with a way to produce enough consistent power to run industry, i.e. smelters & refineries, which product the components needed to make batteries and renewable energy components.
@@lautoka63 No way, the energy cost to produce a wind tower will never be recouped by the wind tower over it's life, not to mention ongoing maintenance, breakdowns and waste when it is decommisioned
This reinforces my belief around the importance of buying less, but when we do buy, buying the most durable/quality products on the market and then taking care of them for maximum life.
@Andrew Earle I agree, but cumulative emissions are what matter now; we're at a moment when we have to leave all fossil fuel use behind as fast as possible. Ditching ICEVs now makes more sense than hanging onto them & emitting more GHGs & other pollution, then ditching them later. It's important to make sure they're recycled, not resold, unless they're still good, & go to people with the most polluting cars, which must get scrapped. Subsidies are important, & not just regressive measures like tax credits. We need to turn over the world's ICEV fleet as fast as possible, & replace them with BEVs to avoid perpetuating fossil fuel use.
EVs pay off the $, energy & carbon costs of their construction in an average of 2 years compared to ICEVS, & of course even old EVs keep getting cleaner as the grids that power them get cleaner, which they are, though too slowly. Transport emissions will only go down by retiring or not using ICEVs. The best ways to make that happen are staying put, walking, bicycling, & PUBLIC TRANSIT! (Including a state of the art national/international high speed rail network to replace flying & long distance driving.) But where vehicles are necessary, sharing, renting, or leasing EVs is smart so the valuable metals, time, & other resources of ICEVs can be better used right away.
One place durability is crucial is in wood use---buildings, furniture, recycling paper... not on just a personal level but with government policy making it easier, if not required, setting up processes & institutions... Whatever's needed.
When people watch something that already matches their beliefs; GL trying to change them.
No one makes a quality vehicle any longer, all plastic pieces of junk.
@@J4Zonian automobiles are not the primary polluter. Industry and power plants are the primary source of air Pollution
@@robertchiarizia9463 Climate catastrophe is an existential crisis. We have to eliminate GHG emissions as fast as humanly possible with a comprehensive emergency Green New Deal. That means renewablizing everything that burns fuels, which means electrifying almost all primary energy. That means electrifying transportation, the main source of GHGs & some other air pollutants in the US. Cleaning up power generation, transportation, industry, & buildings all at the same time yields synergistic effects.
great video. It would be good to look at CO2 emissions on disposal of end of life vehicles
CO2 feeds all life. CO2 cannot heat anything.
Have people heard of bicycles. No one is above taking the bus or the Subway. Have you have seen how obese many people are. Tell me I am correct.
Probably right about the same like the "recycling" of wind turbines at their often far-earlier end of life than modelled...the glass-fibre parts get burned in waste incineration plants (or buried in the earth), the concrete foundations are simply covered up with soil (because they are not usable for more modern turbines) and the shaft of the turbines are the only thing that see a second life as raw material. Batteries up to this day can't be recycled without absurd amounts of new power, ruining every calculation at being "clean"...
MIT had a study. I don't know much about it but it gave the number 12X the energy to get rid of an electric vehicle. Furthermore, batteries need special storage because of the toxic chemicals they contain.
@@1s3ngr1m Well said and great points.

I am currently weighting my options between petrol and electric options while buying my new car, while also looking future gas/electric prices. I cannot decide.
This video reminds me of something similar: recycling. Recycling was designed to make people feel better about over consuming products. The recycled materials are sometimes shipped long distances creating a penalty. Similar marketing strategy to sell a product that makes people feel good.
if recycling were more resource-efficient, it woiuld reflect in prices. but there's no economic incentive to recycle, only political

There's no mention of taking arable land out of crop production to dedicate said land to wind and solar uses. Also, no mention of farm implements that requires a great deal of energy not only to till and harvest crops, but to get produce to local and international markets.
And no mention of the manufacturing costs of oil rigs. Your comment is utterly dishonest. Solar is often feasible - think deserts - where arable farming is not. Wind power production can be done in a manner that does not require taking land out of production. Not that you're biased or anything.

@@saugerriver5769 you are parsing words. Here in indiana farmers till their land and your reading comprehension is questionable.
Some nice thoughts. But, I think it overlooks some of the costs (and carbon use) of operations. Especially, batteries have limited lives - eventually, they won't hold a charge. Before they are completely dead, they hold significantly less than their nominal charge. For conventional cars, this isn't an issue as long as the battery will start the engine. For hybrids, decreasing battery capacity will mean that the gasoline engine will operate more and more. For electric vehicles, vehicle range will decrease. At some point, the batteries will have to be replaced. The carbon cost of replacing a battery in a conventional car is very small, because the battery is very small. The carbon cost of replacing a battery in a hybrid is larger, because the battery is larger and uses more exotic materials. The carbon cost of replacing a battery in an electric vehicle is larger still, because the battery is much larger. I suspect that the whole life cycle carbon use, including battery replacement, is higher for electric cars.
Switching to all-renewable electricity will neatly solve all these problems. Unfortunately, the record so far is that increasing renewables in electricity means that electricity becomes more expensive and less reliable, with fossil-fuel generation required to provide backup for intermittency. We may get to the renewable promised land, but we are a very long way.
That's hardly true, out of my german perspective i can say: watching renewable energy growing and become more and more a thing, means at the same time watching the prize for renewable energy going straight down, outcompeting even nuclear power. Today in germany, Solar Power ist the cheapest energy you can get. Expensive energy comes mostly from politics.
Believe me, renewables are way better then their reputation, just let them grow and develop on the technical side. But i agree: it's still a long, but worthy to walk for sure.
@@kornelwojtkowiak9435 Does that trip to renewables include cutting and burning wood for available heat this winter in places around Europe? I think there is a problem there!
batteries demand one of the most scarce minerals on earth. also don't forget about the amount of co2 the machines use to exstract those minerals
Not all parts of new technologies develop or evolve at the same pace -- ESPECIALLY WHEN CURRENT TECHNOLOGIES HAVE FOR-PROFIT REASONS FOR STALLING AND BLOCKING. What's important is that we start, and solve challenges as we move forward.
@@chuckscholl9928 Sorry mate, but i dont see this thing happening here. Exept maybe for Ukrane right now, but that's ofc another topic. It's really more like people getting big solar installation to heat their outdoor pools with air-to-heat. Don't mean to brag, but that's the reality here.
I absolutely agree that the energy / pollution / CO2 equation for electric vehicles has to include the source of the energy that powers the vehicle.
What I didn't hear you say is that the same should be done for fuel burning vehicles. The petrol (gasoline) or diesel fuel you put into your car didn't magically appear in the tanks of the gas station.
The energy costs, pollution and emissions of oil exploration, oil well construction, pipeline construction, pumping, shipping, refining, road transport etc all have to be added to the emissions "produced" by your Internal Combustion car, in the same way you ask that the emissions from power stations should be added to the electric vehicles' emissions.
Also, if you want to point out (correctly) that in many parts of the world, electricity comes from burning fossil fuels, then you also have to consider that there is a lot of electricity inherent in each gallon of gasoline or diesel.
Research the electricity consumption of oil refineries (absolutely huge), realise that liquid fuels are often pumped with electrically powered pumps etc.
One university study concluded that the amount of electricity inherent in a gallon of gasoline would drive an electric car at least half the distance that the liquid fuel would drive an internal combustion car.
So yes, look at the whole picture for electric vehicles, but also look at the whole picture for internal combustion cars, hydrogen cars and all alternatives.
I drive (and love) an electric car, but I have solar panels and live in New Zealand where over 80% of our electricity comes from renewable resources, especially at night when the vast majority of electric cars are charged.
There are studies that prove that the CO2 produced for manufacturing processes for cars with petrol/diesel engines versus battery operated cars are similar. So the CO2 produced is less with the electric car.
Excellent response to this video which has a very misleading & much too narrow perspective.

There is nothing remotely close to it in clean energy production, and over all the years we've used it, very little damage has occurred, and always when safety protocols were ignored. I would love to see the graphs with nuclear energy used. Oh, and we also have reactors now that can reuse the waste, producing basically no nuclear waste. Why not?

Seems like there is a recycling component at the end that is missing from the analysis? How much co2 is used to recondition a vehicle as it may be advantageous from the electric auto
Did not hear him mention the CO2 emitted during the whole process of getting the metals out of the ground when creating solar panels for the renewable energy. But this is a great start for a conversation on the topic.

Interesting how he applied “inside the box” thinking to wind and solar. Totally agree with Sapper6N.
Yes, and all those metals that have to be mined,refined, machined, and transported to assembly plants to build the ICE based drive trains that require hundreds of parts.
@@makerspace533 Well said MakerSpace. I’d go a little further. Any man made thing has a negative environmental impact when it’s creation, use, support, maintenance and salvage are accounted for inside the box. Any “green” product description leaves me suspicious of motive.
Also renewable energy plants such as wind and solar do not last a long as traditional power plants. That being said conventional cars don't require power plants to fuel the car, only to manufacture. Conventional cars do however require fuel processing, but most of these drilling sites are already active. I would totally love to see another video comparing all of these other factors. Great video, lets keeps looking at all the factors before committing to electric. Others mentioned the impact on the ozone from the electric motor also.
A good analysis, but surprisingly he missed the amount of CO2 emitted in mining rare earth elements for solar panels and wind turbines, not to mention they contain massive amounts of processed petroleum products we often refer to as plastics.
And oil extraction or construction of drilling equipment doesn't emit CO2?
@@Javaman21011 Of course oil extraction emits co2, just less than rare earth materials.

@@sayeager5559 Fair enough. I think I missed that chart on first watch.
You also need to consider that building the windmills and solar panels produces CO2.
So you would have to add that to the base CO2 of an electric vehicle.
Very interesting video.
Thank you.
You should search for earth batteries. You can make them with soil or water. The soil has to be moist. Use two different materials for your terminals like copper and aluminum. Make the earth battery in series. These are cheap easy volts to build. Roughly one volt per cell. Then to get your amps, wire a solar panel to the earth battery in parallel. You will have all the cheap green electricity you could ever want.
Great talk. I'm disappointed that you didn't talk about how challenging it is to recycle all of the toxic elements inside the batteries. What a huge oversight.
It isn't challenging at all recycling batteries uses less than 5% of the energy that mining the materials does and is a simple well understood process.

@@clivephillips4021 plant life is essential to feed animal life, if an animal doesn't eat plants it eats another animal that does, that's the food chain. Plants need CO2 as much as animals need oxygen.

The warming crowd complains that the snows of Mt.

He tells us to view the EV as a whole yet he didn't account for Co2 emissions of processing a barrel of oil to gasoline. One barrel of oil to gas (42 gallons) produces 520 pounds of Co2 (237kg)

C02 is not the only component that goes out from a combustion engine, is like saying a cigarrette has only nicotine. Also solid state batteries are coming very soon and with different materials.

Watch the documentary “ planet of the humans” .
Michael Shellenberger has a tedx talk on exactly that and lo and behold, they aren’t great either. Nuclear power is the answer
Nobody is stopping you except yourself.
What about the surplus electricity that the power plants are producing. The CO2 is being produced regardless of the electricity used, and since I've not had a brown out in 20 years, I think they are making more electricity than we are using...... so where does that energy go? So if I plug an electric car into the grid, Am I making the plant produce more CO2, or am I just storing the electricity that they are already producing?
I am writing an essay on this topic. Can somebody provide a source for the information at 9:35
Here's the thing about this presentation... he made up most of the data. Note the disclaimer from TED in the video description about not having scientific evidence for many of the claims in the video.
you mean needing a 3.2 times larger battery for 400 miles in comparison to 125 miles range ??
I would say that it would be impossible to quantify. It's as nebulous as climate change models.
This always seems like a taboo, but what about investing in nuclear energy? Wind and solar are great, but they require an exponential amount of land conversion to generate the same amount of energy as a nuclear power plant. They also require some rare earth materials (particularly solar) and they don't last as long as other power plants. I know nuclear is scary because of Chernobyl and Fukushima, but I think it's time for us to have serious discussion about this form of energy.
Nuclear energy is the obvious answer, send the waste to the moon or mars or China...
The first nuclear power plants were invented in the 1950’s. By the 1970’s the U.S.A. stopped building them, because they were dangerous (3 mile island). So, they stopped building them around 20 years from conception, won’t build new ones with technology and safety improvements made in the last 50 years, thus 70 years since inception. And they weren’t so bad that they tore them all down. I don’t see the logic. Yes existing plants have a had some improvements but that’s not at the same level as better designs from scratch. Proof in the pudding: France is mostly nuclear powered and has had no major incidents. Another topic is to make smaller nuclear plants that are much easier to manage in the event of an incident. It’s not like half the size is half the danger, I think it’s closer to exponential than 1:1. More smaller plants distributes generation, lesser affects of a plant going offline, shorter distances (which create loss), etc. I read an article on Wikipedia about micro nuke plants the size of a truck that can be operated remotely for underdeveloped countries. So, imho there is a lot of merit to your inquiry and a lot of information and technology developed in the last 50 out of 70 years.
Nuclear is the only alternative. Wind and solar don't work, because grid storage batteries don't exist.

Let's not forget that once the life of the car is over, the battery still works. Maybe at 60-70% but that's enough to be used for many more years to store renewable energy. And one day, when it's really over, that battery will be recycled at +95% (more closely to 99% since it will happen in 20+ years). No need to mine those rare earth elements again, they are right there in the battery and ready to be put into the next one. We cannot all go electric all at once, but if you can, go ahead, you're paving the way for a greener future.
Using recycled batteries is cheaper & better for the environment, but also, as the tech has moved on, you'll probably get much more range from the same amount of matetials.
It’s worse than he’s saying because he’s omitted the enormous amount of new global infrastructure required to get enough electric stations around the world. The oil/plastic coated cabling alone would run into millions of miles.
You presume no local power, this is why many Tesla Superchargers have Solar arrays supplying them …
Nor did he mention the co2 produced in manufacturing solar panels and wind turbines which is enormous! And let's not get into having to replace them due to a short lifespan. Nor shall we mention their disposal impacts on the environment. He deliberately mislead his audience in the end!
@@chrisbraid2907 But the CO2 produced by producing your car is enormous and you would have to drive it well past the time you would probably own it to offset that.

Electric stations should be standalone and solar powered, we know this can be done.
never mind half the human race doesn't even have electricity right now. how are they MAKING that electricity they are charging the cars with...? hrmm yep.
Didn't see any consideration of the C02 cost of retrieving, refining and transporting the fuel for normal ICE vehicles? Having worked in the marine Oil industry, I can tell you that's a fair amount to take into consideration. There is also the consideration of generating electricity on large scale vs small scale usage of fuel. I live and work in Norway, where all electric power is generated from hydro electric sources (so that flattens out the graph for electric cars quite drastically, cutting down the CO2 crossover point with ICE cars to somewhere between 2 to 4 years of usage) - which I know is a luxury situation (Norway has over half of Europe's hydro capacity I believe) The gas and oil produced in this country is mainly exported to other countries for them to burn ;-), with the exception of the fuel refined for all forms of transport (road vehicles, air transport and shipping) - although a lot of money and energy has recently been put into coming up with a gas power plant with CO2 scrubbers. My personal opinion is that the electric motor is the way to go for small vehicles, but batteries are maybe not the power source we should be using. Hydrogen is the fuel that should be the focus, but unfortunately the current ways of utilising it are expensive to manufacture, require elaborate storage solutions and quantities of rare metals in the fuel cells (which hinders mass production). Battery technology is currently advancing at a healthy rate, so I don't see hydrogen tech attracting the necessary big bucks (until a 'eureka' breakthrough happens in any case). Most renewable sources of energy that are being invested in are also intermittent sources (solar, wind) which will only be effective when combined with an energy storage solution (which in most cases is looking like battery storage at the moment). I personally don't understand why more money isn't being put into geothermal and infra red energy harvesting, as these both have the potential to provide a constant stream of energy 24/7
"There is also the consideration of generating electricity on large scale vs small scale usage of fuel"
There is also battery charging/discharging losses to consider.
The thermal problem with batteries needing their own cooling system is its own efficiency drain on electric cars - both the battery losses and the cooling system power + weight.
"I personally don't understand why more money isn't being put into geothermal and infra red energy harvesting"
1) Geothermal will get a boosted by a move to use gyrotrons (like magnetrons for megawatt power output) to increase drilling efficiency for reaching the much deeper super hot rock layer that most of the world (outside the active geological zones) needs for viable geothermal power - this drops the price of drilling to about $500k instead of $millions.
2) Infra red energy harvesting is already utilised in some variants of solar power, specifically thermophotovoltaic cells which have an extra layer of energy harvesting material to absort IR which is reflected back when the main PV cell heats up from absorbing bandwidths of light it cannot convert.
I like norways approach to using hydro. Sadly here the intent is on demolishing our dam systems. And everybody is afraid of nuclear, so we’re sold the idea that solar and wind are adequate. Nobody seems to be approaching reservoir or mass-based energy storage and only wants to talk about batteries. It’s like they think the sun and wind are always there and batteries just pop out of a factory with no environmental repercussions. I almost don’t even think it’s about clean energy anymore.
He also did not factor in the cost of building renewable generated power, or the cost of maintaining an electricity network, or the energy cost to transmit electricity, or the fact that the batteries currently being used in our electric cars will only last for around 60,000 miles.

The TED speaker's information applies to an EV with a 125mile range. That means it isn't a Tesla. Every Tesla has 200mile+ range. Teslas have more efficient motors and batteries so they use a smaller battery to produce a longer range. This is true even 2 years ago when Conway made this speech and batteries have come a long way since then. The EV revolution is here. EVs are better than ICE cars in pretty much every way, except for long road trips where charging will take longer than filling up with gas. It doesn't matter who gets involved to speed up or slow down the transition to EVs. There are countless websites and videos on youtube where you can learn about the pros and cons of EVs.

Of course, fossil fuel extraction has zero cost to the environment. Clearing up old coal mines is simple - just cover the hole with a lid, and we're done.
The old argument was "solar is expensive"; stay with fossil. Compare that with nuclear, which is the most expensive form of energy generation once development - and more importantly, cleanup and contingency - costs are factored in. Solar, after some development cost, is the cheapest form of generation. Offshore wind, and tidal need more investment, and also the creation of storage infrastructure, which will be expensive, of course, but what are we to do anyway when the oil runs out, and the planet is so hot that we expend ever more energy in simply moving heat energy from where it is undesirable? Simply crying that "renewable energy has externalities" is utterly disingenuous, or merely uninformed, but in either case is wrong.
I've said this for years. And working in the field of producing EV batteries I see another problem and that is recycling of the batteries. Once glued and welded together they are almost impossible to get apart without destroying them. Creates an awful lot of work in trying to recycle. One that requires cheap labor. And that means shipping them back to where they were created. And how do you measure the amount of CO2 created in all of the shipping of the batteries from the raw materials to the production of the cells to the shipping of the cells to the production of the battery packs and then shipping the packs to the auto manufactures? These things are heavy. They need a lot of space and special handling. And at the end of the cycle you want to recycle them? That requires even more shipping and special handling. I've always said that the green is in the money it makes and nothing else.
And ocean liners produce more pollution than anything.
Money is king, and unless or until that changes, nothing else will, - unless there is a lot of money to be made from it!
I think it'd be nice if more companies could would make the batteries easily disassemble-able...like the Leaf. Maybe the new 4680s will enable that. That being said, we're a long way from battery recycling being an issue. Used EV batteries still pull in quite a premium because of the diy market.
@@willburk you can always reuse the modules. It's the modules that are glued and welded. That's were the diy market comes in. The issue is that once those go you have no other choice but to try and take them apart to recycle. The pack is made up of many modules. For instance on a new SUV we used 2 layers increasing the storage from the standard ones which are anywhere from 80 to 140 kwh to 208 kwh. This is accomplished by just adding an additional layer of modules.

Your Corvette has 400+ horsepower; yet, it only emits as much carbon dioxide as one horse does - that's amazing! :D Celebrate modern internal combustion engines! They haven't even reached their full potential yet... o.O
@@yareksad there might be a TED talk on sarcasm out there for you :D
@@sloreo8278 I am very sarcastic, but not this time. It’s clearly explained in the video that co2 exhaled by a horse is naturally recycled therefore it’s environmentally friendly and co2 from the cars isn’t.
What I can say is there is a tipping point and we can only extend of the deadlines for the tipping point 👉
What about salt batteries, that were used around the times of the Great Exhibitions ie the beginning of the 20C?
Tky
Another factor that he failed to include would be the life span of those batteries in the cars/solar system and the disposing of them after they are replaced. Not to mention the chemicals used in the use of solar panels and disposing of them after their life span.
Solar panel recycling is already done very well in Europe. So it is possible, no obstacle there.
Battery recycling is indeed much harder but there already are companies doing it. But most importantly, after EV batteries degrade enough to need replacing they still have enough capacity to be used for grid storage. So they can have a much longer lifespan then the car itself.
@@walterschwarz29 unfortunately recycling is a hoax as well as using old batteries for grid storage. It's a fantasy, not realistic, no rules or laws will change this. Electric vehicles have a place but they will not replace a diesel nor gas motor, with gas motors becoming more efficient, albeit more than an electric motor in some cases, and types of diesel becoming cleaner as well as electrics not having the range of diesel as well as making that electricity does and will produce pollution. Can't have it both ways and you're blind if you don't look at the WHOLE PICTURE.
@@walterschwarz29 recycling also uses lots of chemicals for leeching and separation and lots of energy as well. Recycling is not a green process.
1) The cells in the battery from an electric are still useful after it is no longer suitable for a car, those batteries can be repurposed such as in stationary storage. They do not need to be 'disposed'. 2) Over 90% of the materials in those batteries can be recovered and reused. And this can be done more cheaply than mining new materials. They do not need to be disposed. Please remind me how much of car exhaust can be recovered and reused.
But you are ignoring the fact that there is already solid state batteries being made by Toyota that get rid of the environmental impact almost all together.
the production of EV's will get cleaner while Petrol cars won't change much.
Also the battery life of an EV is far longer already then the general lifespan of a Petrol car. If we take the usual 300KM as write off point you can already fit 3 petrol cars in the distance of an EV.
so that changes the whole game a lot.
I used to listen to Paul Harvey every day. He would talk about things like this with common sense. He committed on getting energy from volcanoes thermo energy. Moving waters all over this country. Still sticks in my memory. I sure Miss Paul Harvey radio.
....And now you know the rest of the story.
Paul Harvey. Good day.
Thank you. We were considering a plug-in EV. We chose a comfortable sedan with avg 44mph and 52mpg in the city - most of our driving. The easily-recycled battery pack weighs about 36 kilograms / 80lbs. It can be DIY replaced in an hour for about US $2000.
Don't do it. The push for EVs has nothing to do with the environment. It doesn't even make a difference. The electricity that you charge your vehicle with is produced in a power plant that is powered by.....FOSSIL FUELS.
@@jonathanstill4701my electricity comes from a nuclear power plant. Try again.
@SpykerSpeed Ah my dear friend,.you are so mercifully free from the ravages of intelligence. Idk where you're from, professor marvel, but I'm from the US & in the US less than 19% of our electricity is generated from nuclear power. A small percentage is hydro-electric, wind & solar & the rest is....any guesses, smart guy?
@@jonathanstill4701 If you consider 21.5% small, then your statement is technically correct. But your implication is that it's minuscule. BTW - Nuclear production is 18.2% ... so the combine non-CO2 emitting electric production is nearly 40%. And the mix is changing all the time with solar and wind contribution a larger percentage of the mix every year.
what brand is it?
Very good talk - would be interesting to see another discussion that relates to "job creation" and the EV auto - i.e. what is the net effect going forward.
Also, aspects like"
- How much cheaper is it to operate an EV auto before and after the "break even" point?
- What "advancement" would have to take place in battery technology to make the EV auto a winner?
@charliemurphy Though public transit is even more important, EVs are a crucial solution to climate catastrophe & our pollution crisis. We have to renewablize our energy & to do that most primary energy has to be electrified.(Clothesline paradox energy like passive solar heated & cooled buildings).
It costs about the same throughout the life of an EV except for the minimal maintenance costs. (It’s much cheaper to run an EV than an ICEV, & fuel costs are almost certain to get cheaper as renewables are added to the grid.) While there may be some small increase in maintenance as it gets older, the “break even point” isn’t any kind of dividing line.
He tells us to view the EV as a whole yet he didn't account for Co2 emissions of processing a barrel of oil to gasoline. One barrel of oil to gas (42 gallons) produces 520 pounds of Co2 (237kg)
What will happen to food production when all CO2 is removed from the atmosphere since all plants use CO2 to help it produce food and oxygen so how is our lives going to be with little to no food production ???
@@waynemeyer9694 📎 It looks like you’re writing unsubstantiated nonsense. Would you like to turn on all caps?

It is easy to talk about numbers, needs the facts to support it.
His numbers are totally exaggerated to help his claim, which is why you see no sources.
But before references he needs to talk about the CO2 created of drilling oil, transporting it, refining it, and transporting it again.
@@Sam-gf1eb yes! And the environmental damage of oil spills.
and then there's the total energy output required to mine, manufacture and maintain solar and wind farms.. not to mention what happens to these sources when they all degrade..
I saw this video, then was going to put a long reply about the carbon footprint and other issues created by making, maintaining and disposal of all the wind and solar panel farms which have a finite life of about 25 years, but I see just about everyone has sussed this one out. Why is it most average humans have it all worked out anyway! Well done Mr and Mrs average human that’s commented here! 👏👏👏👏
30 US Tons for 180.000 miles = 151 g/mile CO2 emission, for the "conventional car" (gasoline, non hybrid)

I did very similar maths when I chose my car. And came to the same conclusion - - my German luxury-barge, cradle-to-grave, including the fuel it burns, is more environmentally-friendly than an EV. The fact that it's a nice car is quite a bonus as well. I'd dread driving a Prius, or worse, getting stuck in traffic in one.

@@lyerger8232 No, they come out of his rear end. He doesn't cite studies, because every study shows the opposite of what he's claiming: cradle to grave comparisons show EVs produce less greenhouse emissions than ICE vehicle, even counting manufacturing (which yes, is worse for EVs). It's a terrible talk.
That's your opinion.
" because every study shows the opposite ". Show your source. @@markw4206
Thanks for simplifying some of the big issues. However, you’ve left out the net CO2 emissions from production, distribution, maintenance and disposal of wind and solar, as well as ignoring the obvious environmental impact of all the increased mining for every aspect of power production and grid-based distribution capacity.
Just like it has been left out the environmental costs of offshore oil platforms, tankers and massive refineries, imagine the co2 that went into building those?
@@jaytheblader6701 'Imagine'... Sure that sounds like some solid numbers you have there.
@@jaytheblader6701 oil is much more power dense that any renewable source. The only thing better is nuclear.
Change is hard, I know.
@@jaytheblader6701 and all of that has lead us to the point where we can pivot...a delicate point of balance of change...we need eclectic not electric...but we need to move away from oil.
We here in the U.S. can expound all we want on how to solve "Climate change", but until the majority of other large polluters in the world join us it will be for naught. Wind borne Emissions know no geographical boundaries. For example:
If i live on a street with many houses and we all have big yards and large trees. When the Fall comes my trees drop there leaves. I go out and rake them up so my yard is nice and clean. However, my neighbors don't care as much as I do, so as soon as the Wind blows my yard is full of leaves again. I can repeat my behavior over and over, but until my neighbors agree to clean all of our yards, my efforts will have a limited effect. Let's not forget this before we try to mandate or legislate ourselves needlessly.
We have the same argument in New Zealand but both our countries have some of the worst emissions per capita in the world.
Can't argue, except to say the polluting countries will not feel any pressure to "clean up" until clean becomes the norm. If no one takes the first step then the solution will never come.
Who built the van?
What about pollutions of producing solar panels out of high grade silicon, silver and all?
Only way to be completely accurate is to start from the ground up when producing the vehicles/engines/batteries and then as well from the ground up producing, refining and transporting the fuel/electricity to the point of where it gets used, also the products/services related to maintaining each type.
If you do that, then count all the wars fought over oil and gas. And the consequences of the wars (e.g. starvation resulting from the Russian 'special operation'). Add in oil spills, air pollution, oil pipelines, etc.
@@chrismartin7579 Also take into account petroleum is used extensively in building and operating electric cars.
CO2 from the corvette is also absorbed by plants and converted to O2, thus the greening of the planet. Atmospheric CO2 ppm continued to rise during the Covid-19 lockdown period of reduced admissions as reflected in the raw data. This happened due to mostly oceanic off-gasing, but assisted by other natural causes such as increased global volcanic activity. EV transportation simply does not have the grid capacity to support meaningful integration on a global scale.
Plants prefer horse CO2. But that’s covered in another video…
Plants do not know if care where the CO2 comes from anymore than we would care where the oxygen we need for metabolism comes from. This is such a complicated, multifactorial and global problem that one “solution” is not gonna solve it. An eclectic approach is the one that will allow us to adapt to whatever happens. I do agree w him on that!👍🏼
The more the co2 the better it seems...we could actually make ourselves plants and animals larger by increasing co2 emissions - the more co2 a plant processes the more oxygen it produces...
Yes
And Corvettes also breathe O2
And what about the need to replace the battery that fails long before 400,000 miles?
Why does the horse's C02 go to the plants and create a cycle and the car's CO2 doesn't? What It's different about the CO2 coming off of a car that it doesn't create a cycle with the plants and create more oxygen that then goes back into the pistons to create more CO2 just like he claims that the horse does?
I'm an electrician and a huge fan of Tesla , the man not the company , I've known this for years , in the future these cars will be a game changer , but not till battery tech , and energy generation and transmission catches up, The laws of thermodynamics are the ceiling in this problem, they are the brick wall
More than anything, it's just that EVs aren't cost-effective yet. They still use much less energy to drive than ICE vehicles, and they're compatible with any energy source. That's the whole point. They have plenty of potential--but, it doesn't matter if there's no cost advantage. Better in any way doesn't matter if they cost too much.
@@devilsoffspring5519 $20,000 more on average than an ICE. not too many people can justify that.
@@amorgan5844 Never mind justifying it, affording it is the more important issue. I'd love a Tesla or similar "normal" style electric car with a decent range, but £30k-£40k is just insanely unaffordable. My cars are usually bought used for around £6k and last another 5-7 years after I buy them. I think that is far more sustainable at the moment, both environmentally and financially on a personal level.
But the truth is, the US has the cleanest air in the world, and Gas Vehicles are no problem in the first place.
@@amorgan5844 Not many can justify the exorbitant price of many mainstream ICE cars, either. They buy them because they have no choice--they gotta get to work somehow.
I don't understand how the cycle from oil to automobile to CO2 can't include the CO2 continuing to plant life? When I was young the oil in the ground was understood to be "fossil fuel" from deposits of dead plant and animal life. Makes for a long cycle, but still a cycle.
This is an interesting talk with some interesting analysis.
Yes. Ultimately it's is a cycle. Eventually the produced CO2 would get sequestered at the bottom of the ocean and deposited as new coal, oil etc. The problem is that this cycle is extremely long at least on our civilization scale (we are talking about 10 -100 million years).
We have been here as a species for a couple 100k. Some 10k since the end of Stone Age. We burned all fossil fuels so far in like 200 years.
The natural cycle is just too slow to be useful to us.
Because fossil fuels bring in long stored 'co2 deposits'. If you bring that in, you also need to get that back out in a similar way. Sure the planet itself can deal with such a long term cycle, but most current life (including us) can't. There are attempts at putting co2 back underground for long term storage similar to how the gas ,coal and oil was locked away, but these are very very expensive systems and not very efficient.
He's missed the point that the corvette DOES CYCLE Co2 and O2. An internal combustion engine requires O2 in order to burn fuel.
Exactly
based off this graph the cars that run on petrol ICE have 52+ MPG please tell me what brand of car does have that kind of mileage?!?!?! I need to by this type of car ASAP!
I wish our government and OEMs can use his logic. I was also hoping he would pitch for nuclear energy as solar and wind turbines need lots of CO2 to build and not efficiently transferring electricity.
@@MyVideosDon I agree. Thank you. Efficiently is best for nuclear energy if we put politics aside. But we are not smart…we should study France versus Germany
He should put his CO2 model he uses for vehicles into the renewable generation. In other words, how long will a wind turbine have to run to offset the CO2 produced from its manufacture
I only goto town about once a week. I had planned to buy a second hand electric vehicle and build a solar recharging station so it would be completely self sufficient. I started looking around at what was currently available. When I started doing Insurance quotes to see what was the most cost effective I noticed that Insurance on an Electric Vehicle was way more expensive. In some cases roughly double what it was on a car of the same make and model but with a gas engine. I ended up shelving the project.
If you get a Tesla with full automatic driving the insurance costs go down dramatically. Fewer accidents the reason. I have a 2020 loaded Tesla Y. Less than $100 a month.
And crazy fun to drive!
@@teresaalbin-davis4529 hate to upset you, but tesla rank near the bottom for reliability in the american journal that measures this. the self driving software in a tesla is more fault prone than the mainstream manufacturers. there is nothing in a tesla that you cannot buy anywhere else.
@@TaylerMade have you driven one?
@@TaylerMade two years problem free. Self driving especially good in stressful stop and go traffic.
For conventional fuel only the co2 coming out of the tail pipe is taken into account but for Electricity co2 during Electricity production and the battery production both are counted.
What about the co2 produced by the oil industry from start to finish when an electric pump is needed to fill the tank and again an electric pump is needed to take the fuel to the injectors which again need Electricity to finally burn it.
Wonder why the co2 of fuel per leter before it is pumped in the car is not mentioned at the fuel stations.

Strong valid points, glad you made this video to clear up the understanding of Co2 emissions.
I can’t figure out what side this guy is on.
Where is the data showing time lines for renewable solar and wind power offseting the carbon involved in building the wind and solar farms?
Engineering is all about trade-offs. There is seldom one single best answer because there are too many variables. This talk does an excellent job illustrating that and proposes one or two different ways of trading things off.
He's pushing ICE and hybrids in 2022. While hybrids are viable, EVs are the way. There is just no cogent argument against EVs while pushing ICE that I could find. It's all just cherry picked and twisting facts to demonize the EV.
Except for the argument he makes.
@@glennsills excerpt for arguments that are cherry picked or straight up distortions
Although this guy clearly understands the issues that most do not know, and his talk is mostly very good, at ~11:30 minutes, he hypocritically implies that wind and solar are so-called "renewables", although it takes a lot of energy to make THEM, too.
He does make good points but he is not producing the whole picture.
He also neglects to mention the CO2 produced by vehicles that transport the fuel all around the globe to all the gas stations to support these vehicles. The gas does not magically appear at the gas station.
He also false claims that combustion engines have not be been optimized. This is a matter of opinion.
He also gives a simplistic idea of what development, research, and investing. People with billions to invest don’t generally give away that money on proof of concept alone. Things need to been scalable.

Oil is renewable source of energy. If you return to wells which were depleted years ago you will find oil once again. How's that?
I know this is old, I wish he clarified 2 mode hybrid vs a mild one.
I interviewed a top energy expert on my home page vid. A must watch interview. The expert warns that EV conversion will not happen and oil can never be replaced.

Something different to make us think rather than just accept.
In many countries there are already national blackouts, and both construction and farming machines among others, require a lot of power, and these should also be included in the picture for the future.
You will go crazy with the cost and time spent to buy food and wait for highway and construction projects if battery power is required for heavy and agricultural equipment.
@@karlsnow5281 *starve to death
Plants absorb CO2 however that is produced. If they absorb the CO2 from a billion horses, they also absorb the CO2 from a billion corvettes. Of course, the corvette doesn't eat plants, so we land with more or bigger plants. This is well recorded to be happening.
your third sentence is confusing, I'm not really sure what your stance is lol. but the concept of the CO2 in horses being in a cycle that the CO2 from corvettes is not, is derived from the corvette CO2 coming from the ground, a closed system, but is now in the open atmosphere, increasing the overall amount of gasses filling our air and increasing the burden we put on plants to convert it to oxygen.
Additionally, a combustion engine releases Carbon MONOXIDE not Carbon Dioxide. CO = not good - CO² = Fourth building block of life itself.
@@isaacringling3823 A part is a reasoning that falls in the category of CO2 capturing. But CO2 only stays captured in the wooden parts of trees if we don't let the plants die and rot (that releases almost all the CO2!). So every year the amount of excess CO2 needs to be captured by new planted trees. Died trees should be shot to Mars (to there create a biosphere) in a CO2-free rocket 😄
The other part is that higher levels of CO2 give raise to plants absorbing more CO2 (larger plants). But as plants die, it doesn't help to reduce the effective CO2.
Unless heat and drought kill the plants…….
@@JohanHaspeslagh what are houses made from?
There is a glaring problem with this analysis, first it's assumed the whole car is just scrapped after 180k miles, whereas in reality a battery can be recycled over 90%, so the next car that is built doesn't have the same emissions. Secondly, research is ongoing for new battery technologies and mining with BEV, if the whole chain of producing a battery was CO2 neutral then the initial emissions would also be lower and third the production of "green" gasoline would require vast amounts of crop fields that cover the entire earth to produce enough ethanol to satisfy the whole fleet of ICE vehicles. So it's a complex problem, but BEV is the way to go together with replacing our old coal/oil/gas powerplants with renewables and nuclear. But replacing all cars now isn't realistic, if I had such a button it would just as easily be a button for replacing the whole grid with renewables :)
I enjoy it when they compare electric vehicles to petrol ones, but they always seem to miss a significant aspect: how is the petrol produced? I would like to see the entire process and the costs involved in extracting oil, transporting it to refineries by boats or trucks, and, upon completion, using trucks to transport it to service stations.
well well well, how are the freakin batteries produced pal???
Hey mate, that's another important aspect to put into the equation. I would like to see a video where all aspects of production, maintenance, and end-of-life for these products are compared.
