Reducing total energy consumption by 80% isn't going to happen short of a nuclear war or equivalent event. Even with fairly extreme energy conservation efforts

Reducing total energy consumption by 80% isn't going to happen short of a nuclear war or equivalent event. Even with fairly extreme energy conservation efforts, the total amount of electricity used is likely to go up as people switch to using electric vehicles for transportation. I think we need a lot more renewables and probably more nuclear too. Whatever it takes to not be burning coal and gas. (And there might be an argument in some cases for building gas plants to replace coal plants. But I'd rather than money and effort were spent on something better.) I don't see a realistic path forward for hydrogen, except maybe as fuel for aircraft. Batteries are good enough for most things, and a lot more efficient.
