Yes, agreed.
> Moreover a single nuclear unit costs billions to build, billions to maintain, billions to dismantle, all under control of a single entity/company. Whereas renewable costs are much more spread, can be managed by many different companies, etc.
The government should ask nuclear power companies to post a bond upfront to pay for the dismantling.
I don't think the whole 'single entity' thing is that bad. Nuclear power plants are still relatively small compared to the whole power infrastructure of a country. They are not more concentrated than eg hydro-electric generation from dams.
Just to be clear: I'm not arguing against renewables here. I'm arguing against turning off nuclear power plants that are already running, and have modern-enough safety features.
(Though I would argue against giving direct subsidies to both nuclear power plants and renewables. You should tax emissions, and let the market sort it out. You can even re-distribute the take from that tax to all voters, so that the average person doesn't have any extra tax burden.)
