>>20180901That may be true, but no one is willing to pay that amount, except, perhaps, for wind and solar -- not for nuclear.
Plus all nuclear is useless in war. Ukraine's energy system was mostly dependent on nuclear reactors. All have been shut down for two years due to the war in the east and the risk of an accidental or deliberate strike on a nuclear plant, which could cause an atomic explosion or a meltdown.
To bet 100% on nuclear is to bet the days of serious war are over permanently. That's a foolish bet to make, knowing human nature and its fundamental flaws.
Of course some nuclear belongs in the mix, but to say the world should run 100% on fission power plants isn't realistic.
