I think with a bit of work and some technical help I could devise "A PLAN" that wouldn't satisfy everyone, or even a majority, but it would perhaps provide the most benefit for the fewest dollars spent.
I'm fairly optimistic about EVs (and autonomous), and that is another demand side for the System, even if a lot of it is at night.
My PLAN would include nuclear, and spent fuel reprocessing, and a standardized reactor design. Maybe the SMRs could play a role, they seem to be getting closer to reality, maybe. The Grid thing might not need to be nationalized IFF we could harmonize its components with some sensible "regulation". Texas is doing its own thing.
I am curious why more private homes in Phoenix and LV don't have PVs on the roof. What is the barrier there? Upfront capital could be allayed variously.
I'd want every wind turbine to include decommissioning fees upfront. Same with anything else. The goal would be to eliminate nearly all coal fired e generation by say 2030. Nuclear is the best substitute.
