I was mostly being facetious. We probably don't have enough time left to build fission power plants (and certainly not fusion) before the level of CO2 in the atmosphere will lead inevitably to catastrophic consequences. According to the IPCC, we have to cut global CO2 emissions by 50% before 2030. So your vast fleet of nuclear power plants might just barely be coming online by then. Maybe. If you started getting regulatory approval yesterday and nothing goes wrong at all.
