There is none except hydro and nuclear for base load. Unless you want to burn gas (co2) or coal (co2 and radioactive emissions that cause more cancers in the us then nuclear has world wide)
Renewables outside hydro cannot, and will never, be able to provide a a stable base load for the grid, battery storage isn’t there and has all sorts of issues, pumped storage requires even more rare conditions then hydro, as does geothermal, so we are left with nuclear as the only real clean and reasonable path forward that we would have done decades ago if not for oil and gas doing everything to prevent it.
So what is YOUR proposal to provide a stable base load?
