    In case of nuclear winter, I don’t think renewable energy is going to be the main concern.

    However, it is possible to put solar panels on satellites that transmit the energy down to the surface. It’s costly and dangerous, but a benefit over surface solar is that the satellites can point at the sun for longer time during days and send the energy to places that are not in the sun, thereby producing solar power 24/7. It’s wildly impractical and expensive, but in case of nuclear winter it may be a realistic solution.

      Wouldn’t the dust in the atmosphere also prevent energy transmission just as it does solar?

      Wind, still works

        You’d use frequencies that can penetrate cloud cover in that case, it wouldn’t work otherwise because then it would still be subject to weather.

          I don’t know for sure but it’s particulates that make it a nuclear winter, not just cloud (water) but would also need to penetrate the clouds as well.

          It’s probably not wise for me to Google “what frequencies of EM can penetrate a nuclear winter clouds” though 🙂

            That’s actually a pretty good point and I don’t know how it would work either. It would definitely interfere with the signal to some extent.

          Some sort of orbital death beam? I seem to recall a 2000ad story around a space energy beaming facility that goes horribly wrong.
