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.

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.
Can someone just send me the answer I’m like 4 weeks late

Helped alot for my test
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!
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.
What are useful information for my project at school ! Thank you National Geographic
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.
It makes sense
Thanks for the video. It helped in my project
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 :)
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.

Oh yeah thx! XD
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?
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..👌👍
Only in quarantine
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

Very good information for the kids as a teacher l give 5 star rating
Everyone : Who came here for school assignment
Me: who voluntarily search for it because of interest 😂
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 didn't used to believe in solar energy,now Im "warming"up to the idea=)
Love the quality! It's what I would expect from National Geographic.
um is this a primary or secondary source? i need to know for school
Cool, future is on Renewable energy
omg so relatable ty!

Very Nice
Nicely explained.
I was definitely not on this because my online school sent me a link to do this (*gulp*), definitely.......and I guess I like studying.
Also, all the comments say 'Who else was sent by school?' when some people probably weren't and are now making sad studying noises.
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.).
I am the teacher preparing to send my students here!
Don’t know why people haven’t tried to absorb some energy from volcanoes
Go nuclear
Who is here because of their teachers
I was sent here for school too.
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.
Excellent presentation
Love it !

we can all agree we are here because of our science or geo teachers....
So helpful! It helped me out a lot!
I like this!!!
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
1:34 not all. Solar and wind power are quite unreliable
This video should be shared!
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.
Nuclear energy is not a fossil fuel. It is a "metal" fuel at best since uranium and plutonium are metals. Cool video though.
Literally says in the video "not a fossil fuel".

Ask in a forum local to your country. I can't help you with that, unless you plan to study in Spain.
i’m like a month late but i’m here because of my teacher
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)

This video helped me
As some of what is said in this video is true they do forget to mention that renewable energy would not be possible without fossil fuels as solar panels, wind turbines, and construction would not be possible without it.
The video did mention that there is energy use in the manufacture of the equipment, as well as installation, transportation to the site, and maintenance. No different than any other generating facility. The difference is, they don't require the continuous extraction, refining, transportation and combustion of fossil resources, to continue producing electricity. The "fuel"(wind, sun) is free, and even delivered for free. The amount of resources needed to fire a fossil plant is many times the burden on the environment, than the initial construction is, over its useful lifetime. With wind and solar, that investment in resources is made only once.
@@vincentrobinette1507 Don’t forget geothermal and hydroelectric.
@@nousername5673 Where available. However, if you have access to either of those resources, they greatly reduce the need for electrical energy storage. Energy storage is the most expensive part of maintaining any renewable energy system, if you want 24/7 power availability. Wind and solar are intermittent, Hydro and Geothermal can generate power continuously.
