Anything else is pixie dust.
Also hydro. But then that resource is by definition limited and much of it has already been developed.
Absolutely. Nuclear, including breeder reactors which dont generate plutonium, should be fully reexamined based on the transcendent difference in the availability of computation for simulation which can predict the results of whatever options are available in contingencies.Three Mile Island happened due to inadequate control due to inadequate situational awareness. That was in the computational Mesozoic Era. Japans experience proves that opening up a waste storage facility is mandatory right now, and would make more reactors safe.
But first we should resort to natural gas. And stop arbitrarily trashing coal-fired power plants.
Coal, nuclear, natural gas, and oil.
Anything else is pixie dust.

Hopefully google will fund one of the 5-6 msr lftr portable nuclear reactor companies out there that run on cheap thorium and nuclear waste.
This technology will deliver the baseload electric power at prices that are 1/4-1/10 of current cheapest coal
