I was assuming that hydro, nuclear and such would keep the led lights on while people sat under a blanket and read a good book in their well insulated homes until they could turn industry back up and start charging their cars again. Living in harmony with nature would not really be that different from heating your water at night with offpeak electricity. If it gave us cheap clean power bills I think people would like it. Not turning the planet uninhabitable might be considered a perk too.
