@BillBones Proven reserves of uranium ore are sufficient to nuclear power the whole world for a few centuries. Proven reserves of thorium could power the world for millennia.

The best answer, so far as I can see, for the unreliable nature of renewables is vehicle to grid. There are already enough BEVs to store a significant amount of energy. As BEVs proliferate, the storage capacity built into them will become enormous. That enormous storage capacity could be used to feed power into the grid when needed. There are, of course details to be worked, the most obvious one being how much the vehicle owners will be paid for making their vehicles available as grid storage devices.
