given that we dont have nukes, and we wont for 10 years even if we started today, and we arent going to start them because theyre economic disasters...

in the medium term its going to be batteries + solar/wind + gas backups for rare weather events. If we get the total annual use of gas down to a very achievable 10% we're still massively winning climate wise. California is getting there, 45% gas in 2022, 25% gas in 2025, and adding batteries at massively increasing rate. Full coverage of an average night is within sight, using gas just for shortfalls.

We can hopefully transition the last peaking gas backup usage to something else in the long term (hydrogen? SMRs if they ever exist?) but it isnt _that_ important in the grand arc of saving the climate.
