As a kid I can remember the propaganda about 'Atoms for Peace', in the 1950's.
Part of this bullshit was free electricity for everyone, an unlimited amount, all from nuclear power generation! Run, presumably, by the State.
Only businesses and manufacturers who used huge amounts of electric power would have to pay, and even then, it would be incredibly cheap.
As a kid I thought we were headed into a Dan Dare world, free power, travel to the planets, wow! Kids sometimes have a great imagination!
