what are you talking about the nuclear power plants of the world have prevented gigatons of CO2 emissions and could have gone a lot further if the decision makers weren't a bunch of nincompoops who share a bed with the oil lobby.

Up from 5 bn tons a year when nuclear power started around 1950 to 35 bn tons now. I think the Elon Musk type strategies have more promise. Not to say we shouldn't have nuclear but it still has the same problems it always had - slow to build, expensive, unpopular.
