My favourite thing about the EV green brigade is that some of these green cars are being powered by coal to recharge them
Which brings in the issues for the average person to own a EV, hell, our power supply struggles with every man and their dog running AC in their houses
Imagine everyone plugging in their EV into the grid at 1800
I believe the answer is ethanol, but to supply enough ethanol to "fuel the world" we would need to infringe of land that typically grows food crops
If we dropped, and held the world population by 50% we would be so much better off in relation to the environment and overall sustainability

Or if everybody has an EV, you can borrow someone else's charge (by drawing it back out of the car) to replace it later. A sufficiently complex power ordering system could turn everybody's house into a giant set of batteries. Build more solar and wind, store excess power generation, then drawdown later...
You are right though, the world is hooked on the ultimate personal mobility item that is the car. Nothing else can beat its ability to go exactly where you want, when you want. Realistically to ensure future resources, the whole lifestyle has to change. Will it, who knows...
Ethanol is OK, but low energy density for production. You need to chop down the rainforest or use vast amounts of water to grow enough of it.
Green hydrogen is a good answer, fast to fill up and very low CO2 impact.
I recently read an article about a vehicle Land Rover had under development.
Hydrogen electric!
Basically hydrogen engine to recharge batteries which in turn run electric motors, and to refill hydrogen tanks takes about the same as a petrol tank.
So more of what we are used to with ICE motors but substantially less climate harm etc.
Been around for a while now.
