That's pretty cool but I'd rather we achieved energy independence this millennia.
Collapse of civilization would deliver a kind of energy independence, but maybe not the kind you want.
Power from renewables is so radically cheaper than anything else ever known that not building it out as fast as possible costs strictly more. That building out renewables fast enough might fend off global catastrophe is an extra benefit.
Building nukes would steal capital from building out renewables.
In any case, NG aside the important distinction nowadays is between technologies with and without substantial opex: NG, nukes and geo are on one side, wind and solar on the other. And capex, same division except NG generation infrastructure is readily retrofitted for synthetic fuel.
Wind and solar are so radically much cheaper all around that it makes no sense to talk about building anything else.
