>Nuclear power is only "5x" higher cost if you utterly ignore the environmental catastrophe of fossil fuels.

Well, from, like 1960 until about 2010 everybody who built a power plant did exactly that.

And, from about 2015 onwards if you didn't ignore it it's still 5x more expensive than solar panels or wind farms.

So, between "expensive" and "people who hug trees and have no power", maybe it's the tree-illuminati people.
