Nuclear is not coming online in the US. Your choices now are: Renewables or frequent regional outages. Given the state of our infrastructure, I think a mix of both is in the future.
The USA has 21 proposed reactors. 0 under construction, 0 planned. It is unlikely any of the proposed projects could go online before the mid- to late 2030's.
It's obvious to you and to me that nuclear is the most capable and scalable and should be our primary choice moving forward.
Nuclear fission as an energy source is a dead end in America, and that has little to do with nuclear hysteria and more to do with infrastructure funding, NIMBY, and wealth inequality. (our bad politics are why we cannot have nice things)
But the reality is that we (the US) won't be taking the best option. So it's time to discuss secondary and tertiary options.
