@Ghst-tl9ec Not as relevant as you might think. Even if the EV is mainly charged with non renewable electricity the total CO2 emissions are still lower than any petrol or diesel car. The point is not whether solutions have no environmental effects at all, but whether they have LESS of an bad effect than the current sources of energy. And that is truly the case with windmills and solar panels.

@tejarshihardas8707 Obviously we have to minimise consumption in general, but this cannot replace the need for renewable solutions like solar and wind.

@tejarshihardas8707 Everything has a carbon footprint lol That’s not the point.

Nope

It is.

Wrong. About 20% of CO2 emissions come from road transportation. Construction industry is another major contributor, but not the biggest problem.
1
@clxma Literally all google results point towards ~20%
1
@clxma If Greenpeace refers to passenger cars that may be correct.

Except for Tesla

Sure, super capacitors charge really fast and have a very high power density. The problem is that they have a much lower energy density than a battery.
1
Of course this is important. But even more important is to get emissions down as fast as possible.
1
@stripyrex_gaming 1. Shortage in mining capacity of materials (mainly nickel). 2. Engineering the machines that can produce new battery tech in large amounts efficient and fast enough.

Hahaha hydrogen has been 'around the corner' for decades. It's a dumb technology because it is waaaaay too inefficient and complex compared to batteries. Will never catch up.
1
You mean, after 10 to 15 years. Current batteries last a looooong time. Recycling is being prepared for, look up Redwood Materials.
1
Oh yes absolutely. EVs are much better. Diesel and gasoline are so horribly inefficient that it is quite easy for battery tech to cause much less pollution.
1
Voor EVs total production emissions of the battery pack are at about 100 kg of CO2 per kWh. Not too bad and definitely worth it.
1
@ok0_0 Will definitely play a role. You still need batteries though.
1
@OneWildTurkey As in, in-vehicle reactors?
1
About half of the comments are about this...
1
Efficiency is not the same as energy density.
1
They will be reused and eventually recycled in large recycling facilities. And no, they do not live short.
1
@RealButcher Yes really. Yes, in stationary applications because they do not require very high power cycling so that is absolutely fine. This is already being done. Recycling plants barely exist because there is barely supply of used EV batteries. Proper batteries will outlast the vehicle itself.
1
Of course. Nobody will deny that. But if you really need a car, the EV is a much better choice. It's all relative.
1
@velokernow3696 Old cars will just be replaced by modern ones in a natural way. Exactly like it has always been. The only difference is the electric drive train.
1
@velokernow3696 Except for emissions. That’s the key thing.
1
@velokernow3696 Nope, total emissions of EVs are much lower. That’s the whole point. And of course will older vehicles be exported to other parts of the world. What is the problem? There they will replace even older cars and eventually electric vehicles will also make their way down there.
1
@velokernow3696 Cobalt is used in large numbers by the oil industry for refinery processes of diesel and gasoline.. And yes, of course it’s best not to have a car. Everyone knows that. But IF you need one, it’s best to choose an electric one. And by the way, within 10 years there won’t be a choice at all to make. All new cars will be electric.
1
So what do you propose.
1
@AnimeHumanCoherence exactly
1
And a normal car emits a lot more CO2...
1
Batteries are a perfect way to depend less on the grid.
1
And that is exactly what battery technology allows us to do.
1
@forgetyourlife so what do you propose?
1
@forgetyourlife Of course. Nobody says that battery technology will fix everything. It will play a vital role however.
