Solar panel and wind power on every house with storage battery up back for night/weather issues. Oil companies don't want people to be self-sufficient. Yes, this is expensive but you have to start somewhere.
Dominique the thing i dont get is i live in a ffarm community and two fields were turned into solar panel fields... when the town is 5 minutes away and has apartment buildings with room for solar
That does sound crazy. A lot of cities don't want the solar panel on houses. which I think is the #1 issue. Power companies control the land and where solar panel go.
thing is, this doesn't even have to be THAT expensive, especially if town councils help to consolidate orders for homeowners. if you're buying individually, there's bound to be some markup; but buy as a collective and you would get some sizeable discounts.
now, if the entire city was committed to retooling its power grid for renewable energy, the costs would certainly be reasonable and it would create jobs. there are few industries and capitalist ventures more moral than renewable energy... why are people so cowed about doing this? sure, oil companies and all that corrupt bs will do their propaganda, but PEOPLE have a choice whether to listen to them or not.
I don't get this also. I would rather first all the homes (that don't get shade from trees) have solar roofs, AND retrofitted windows, newer toilets, and insulated houses BEFORE sacrificing farmland and desert for rows of solar fields.
On an acre per acre equivalent, nuclear can produce WAY MORE MW's of power than solar or wind can. I consider myself a conservationist/environmentalist before a renewable energy enthusiast.
the best reason i can think of is a lack of coordination. without consolidating orders, it would be pretty expensive for each individual property owner to buy and install a few solar panels sporadically. this is where capitalism sorta fails, since you really need communitarian action to take full advantage of economies of scale.
i believe the most efficient course of action is to have town councils create ordinances promoting purchase+installation of solar panels en bloc, zone by zone. the tender would be put up for public auction, and the company that bids the best price gets the contract.
the worst reason is that behind the scenes, a lot of corruption is going on... big oil and big auto stuffing coin into legislators' pockets and so they look away from pesky regulations and to their sugar daddies. that would really really suck tho.

Welcome to another episode of what teacher made me watch today!
Hello fellow weeb
@@caitlin2772 do you know what “weeb” even means?
welcome to day 96 of dad being the better teacher
When we inevitably go fully sustainable and use geothermal, biomass, wave energy, tidal energy, solar and wind, cheap stable power will be the norm by ...
1: Using many renewable sources as listed above as even on a windless night the others are unaffected.
2: Using suitable energy storage like batteries, pumped water, liquid air, biomass, hydrogen gas, molten salts, compressed air, pumped hydroelectric power, flywheels and many more.
3: Trading energy over large distances, across continents then eventually the globe. This would even out supply and demand. This is one application that capitalistic free market economics would be most helpful by quickly managing demand and supply at all levels of electricity supply from micro grids to the largest scale.
No new technology is need to make this happen as they are all currently in use, many for years As promising new technologies become available they then can be easily integrated into a modern smart grid systems.
What are useful information for my project at school ! Thank you National Geographic
Thank you so much you helped me a lot with my really hard project thx!!!!!
Thanks for the video. It helped in my project
thank you for helping me to study for my quiz and test
did you do good tho?

My name is Setya Faturahman from SMK Bakti Nusa. I think renewable energy is an alternative to traditional energy that relies on fossil fuels, and tends to be less harmful to the environment. With this, the environmental damage caused by relying on fossil fuels can be reduced.
amazing video ...as it briefly describes renewable energy and its advantages n disadvantages...so it vl provide help to people to install n maintain renewable sources of energy by keeping in mind the advantages and disadvantages in order to evaluate whether to use it or not..👌👍
Can someone just send me the answer I’m like 4 weeks late

It makes sense
So helpful! It helped me out a lot!
Love the quality! It's what I would expect from National Geographic.
this video is great, it explains us perfectly. plus she helped me for an exercise
How about we use GRAVITY in a different way for energy!!!!! We can use mountain sides with rail track that goes top to bottom. Have water pipes at top. Fill train cart with as much water as possible. Utilize a hard slope to assist in cart acceleration down a tall mountain. The brakes can generate emissions-free electricity while pulling up another cart from the bottom to the top (but empty) I mean if windmills can be a thing then so can using gravity as a source of energy. Hopefully this should free us to repurpose trash into bricks that we can use to house the homeless using gravity generated energy.
These options may be sub-optimal to the educated engineer, i understand that i just want to point out that we HAVE OPTIONS!!!! all we need is real unity!
broski i literally had to rewatch this a billion times just to get the answer
Roadster 2.0 go's from 0-60mph in 1.9 seconds - making it the first production car to accelerate to this speed in under two seconds.
It will also go from 0-100mph in 4.1 seconds and cover a quarter mile drag strip in 8.9 seconds.
In addition to this it has a range of 620 miles on a single charge which is almost double what the Tesla Model S has, thanks to its 200kWh battery.
Battery technology has come a long way and is improving rapidly.
this video helped me a lot lot lot!!! TYS!!
Because of politics..these technologies are still dream for common man
These technologies are a dream that is now coming true.
Glenn Cordova I agree their are more and more of these technologies getting constructed all over the world as we speak its a constant process

How many metals need to be mined to build a windmill? How long does the windmill last before it needs replacing? Where does in go? Recycled? Landfill?
Thx for the teaching
"Once built the are cheap" Nice dodge lol
The added advantage is the generation of renewable energy is possible at all locations on earth,
bringing an end to war for territorial advantage, and shipments/distribution of fossil fuel products. 👍
What’s not to like?
Thanks so much!! I’m writing an debate article for school and you made a really good point :)
I came across videos to another renewable energy technology not listed in this video, but looks to be the ultimate - even better than fusion energy. They have a long name but I remember them by H2IL. They have some brain storming videos worth looking at.
That helped a lot thx
I’ve spent half my time watching this video scrolling through comments
I didn't used to believe in solar energy,now Im "warming"up to the idea=)
It is an interested subject really need to know about it more in to details and make more researches maybe later on can help in changing also as well.
(I came from my teacher but really liked the subject and so interested about it)
Cool, future is on Renewable energy
Bruh, when you need watch things for your assignment
father's assignment for me
Nice .. thanks
Im just here because there's always something new to learn.
Hi fellow classmates that are watching this =)
Reply if your here for school or your in my school Xd
Ps. The video was cool lol
Hi fellow student! :P :D
I got sent here due to a lecture
Good for my y7 renewable energy project
thank you soo much we use for lesson :)))))
I’m here to prepare for my interpretation test tmr 🤷♂️
The reality of wind energy:
More co2 is released in producing just the cement used in the foundation of a single wind turbine than that wind turbine can offset in its entire working life. That doesn’t even include mixing the cement, transporting the cements, steel and various components, the manufacture of steel and alloys used, protective coatings, lubrication and maintenance. Nor does it include roads or grid connection.
There’s nothing green about wind farms!
You can do the math yourself.
30,000 tons (60 truck loads) of cement is used in a single wind turbine. 1800 lbs of co2 is released into the atmosphere to produce 1 ton of cement.
1800 x 30,000= 54,000,000 lbs of CO2 per Wind Turbine.
How is that green?
On average 3000 new wind turbines have been installed each year since 2005.
3000 x 54,000,000 lbs/co2 = 162,000,000,000 lbs/co2 increase per year.
As of January 2021, the U.S. Wind Turbine Database (USWTDB) contains more than 67,000 turbines.
67,000 x 54,000,000 lbs/co2 = 3,618,000,000,000 lbs/co2.
All these Wind Turbines only produced about 338 billion kWh in 2020.
Now remember we’re told that Americans and their gas guzzling SUV’s are the number 1 source of atmospheric CO2! However, The U.S. transportation sector - which includes cars, trucks, planes, trains, and boats - now emits 1.9 billion tons of CO2 annually.
But wait! to add 3000 wind turbines each year, we need a lot of cement! That cement produces 162 billion tons of CO2 each year. Isn’t 162 more than 1.9?
Remember, that’s just the cement production! That doesn’t include transportation....
Still think wind energy is green?
It’s estimated that 1.17 million birds are killed by wind turbines in the United States each year. Doesn’t that just make you feel all warm and fuzzy inside
Yawn.
floating winds turbines. no cement. problem solved
Facts
Bro turned into chatgpt
Soooo many incorrect stats.
You only need around 500 tons of cement, not 30.000 per wind turbine.
One ton of cement roughly produces one ton of CO2.
So its 500t of CO2 per turbine and not 27.000....
Only in quarantine
It is a best solution to combat climate change.
i support this 1000%
We love your enthusiasm!
@thevso Except when you live somewhere powered mostly by renewables or nuclear (such as Canada, Iceland, Norway, Scotland, Brazil, etc.).
Plot twist: none of these people were sent by teachers and they’re all secretly great students who wish to learn more about a subject they find interesting 🙃
Wave energy is an excellent energy source because it is a clean and sustainable. But the biggest problem is the lack of a better frequency caused by the waves' uneven movements, low speed, and high pulsating forces. But we have a solution to integrate every amount of wave motion in a step-by-step manner to provide a continuous rotation, in the form of a single rotational output at the delivery shaft that can rotate a Powerful Alternator.
A planetary gear set can integrate two inputs at a time without any torque loss. It has also been proven in hybrid car technology.
omg so relatable ty!
The fact that everyone is here because of an assignment unless 00:09% of the people are just like ayo i liked this vid and i learned alot
put it in 1.25 speed

Very good information for the kids as a teacher l give 5 star rating
Good info!
Don’t know why people haven’t tried to absorb some energy from volcanoes
Go nuclear
Renewable energy is infinite🖒😉
But Life is not infinite
solar energy will last billions of years - and that's just energy reaching the earth. look up dyson sphere. wind is essentially derived from solar energy. only geothermal and gravi-potential energy (e.g. hydroelectric dams) are independent of the sun - and those would also last billions of years.
Nothing is infinite. Everything succumbs to entropy and chaos. Your existence is but a bleak, meaningless point on an arbitrary time scale that means absolutely nothing.
Embrace nihilism.
Sadly not true. The sun has a very finite lifespan. Once it's gone, so are the renewables.
Nothing is infinite except infinity itself. We're all just stuck in an eternal cycling wheel of time, space & matter vibrating with life & death in x9999999999999999999 reflections of itself like parallel threads.
To all of you who are here because of their teacher, I am here because I am making a lesson plan for students B) now there will be more of you

Maybe someday the oil industry will allow America to install some.
If only they could come close to the same energy output as good 'ole gas and the combustible engine
@bluesbros620 they would. If we actually focused our sciences on them, instead of pouring it into how to squeeze the last traces of oil from dry rock... and then fighting wars over it.
Since you get more wind at night, solar and wind power is a good pairing.
bluesbros620 how long have we developed gas? How many trillions of dollars have been invested into it? How about renewables? How long have THEY been around? How much has been invested in them? it's just a meter of time. Eventually, oil will become obsolete
Wind turbines for the generation of electricity has been used in farms since at least the 1920s. Solar water heating was used for over 100 years. Old homes had glass panels in the roof with piping under the glass.
i’m like a month late but i’m here because of my teacher
Nice job , I love it☺🥰😍😍😍😍😍
Thank you for the informative video, but wind and solar can produce lots of pollution and emissions during production, installation and maintenance. Additionally, the large reservoirs created by dams produce methane, a potent greenhouse gas, on top of disrupting the riparian ecosystem.
I fully support renewable energy. Coal and fossil fuel are not the only sources to get energy. We all need to see that so we can save the planet!
Nah nuclear is the way to go
