even if you could do this (fantasy), it solves only power to the grid greentards (nuketards and solartards) have nothing to address transportation, since there is not enough raw materials to replace all vehicles on the road in the world with electric battery ones 1:1, regardless of whether they're getting nuclear or solar juice so transport, if you want to maintain it as is, will still rely on hydrocarbons, and then, you may as well have the grid powered by hydrocarbons as well unless you were on some sort of bid to claim there was a crisis and everyone needs to live in 15min cities and ban car ownership,,
