Honestly that seems like a more easily solvable problem than what to do with ~30 billion solar panels and the corresponding battery capacity that would need to be built up if we tried to get the bulk of the world's energy from solar. Of course when someone points out that there isn't enough raw material to make all those batteries and panels, the standard answer is "we'll mine more", but strangely that's not supposed to be an option with mining uranium -- so I am generally skeptical of the "peak uranium" theories. It's not even a matter of needing to turn to breeder reactors, although that's certainly a possibility, but rather it's just a question of mining more, and that always happens as technology improves and demand for a metal increases. But sure, nuclear power is not something that would work for every nation on earth. But it would certainly work well for North America and the EU, as well as China, India, Australia, and Japan, which together account for the majority of the world's energy needs.
