Lifetime CO2 numbers listed here are accurate. The only time NPPs have worse CO2 figures is when they are shut down prematurely (see: Germany.) The actual act of nuclear generation produces no CO2, and mining Uranium is difficult but significantly more efficient than than coal and when comparing the amount of silicon needed for solar to make 1mw compared to uranium needed for NPPs to produce 1mw, the uranium still has has better a better track record. Hydro is a mess with so many different designs that some aren’t that impactful where others devastate entire ecosystems just by existing so it’s difficult to realistically talk about it objectively.

We need NPPs, Wind and Solar if we want a dependable and sustainable power grid, but that’s just one small part of a sustainable future that we desperately need to change the way we live to avert global climate catastrophe.
