right now it's not doable. I dont think battery improvements are gona make pure renewables ever able to solely run an economy.2050, not 2035 - and it's dooable or do you have no faith in American ingenuity? How long have you hated American, my friend?
Windmills are resoucre hogs to produce and cause their own problems. Solar farms are nightmare for the enviornment and habitation
Get the improvements to make them capable of running an economy, and market forces will bring them in.
Hell -give them tax credits
But this idea of all electric cars requires charging stations that will be vandalized.
And they are expensive
All that said, when these problems are solved there is no reason they can't eventually take over the energy market. They are not ready now or teh foreseeable future
