Also, the major problem with putting solar power plants in deserts is that you lose most of your power trying to get it somewhere useful. Expect this to change when we have commercially viable room temperature (ish) superconductors.
Of course nuclear isn't much better in this regard - while we do have uranium deposits, we don't have any uranium mines, and hence rely on imports for nuclear fuel.

do you have any information about fusion development being really seriously continued? It isn't proliferation risk alone that affects the development. It is also about projected cost of the produced energy. Any such facilities would be extremely expensive, typical nuclear plant expensive, and it doesn't look like it will have energy density higher than current nuclear plants as both are limited by the same factors, like cooling system engineering that transfers the energy from core to turbines. Thus the price of fusion energy may theoretically be cheaper than the price of fission energy only by the cost of uranium itself. Permits, regulatory approval process, etc... will not be cheaper. Such cost projections, together with the proliferation risk are the reasons that there is no meaningful development of fusion today.
