Nuclear has 1.000.000.000x the energy density of batteries so yes, but you need dead trees to build and maintain power lines, the power grid cannot be remade after it's current decline.

Tiny local hydro (with natural dam) is the future, but getting a building permit is near impossible. (I leave it to the reader to guess why)

We need to switch off electricity for everything except (low power) computers and networks. = hand pumped water, wood stove for water heater, earth cellar as fridge!

Mass transports are completely over, grow/breed/preserve your food locally!
