Also the incredibly long supply lines that go to fossil fuel plants. Solar panels aren't as green as we like to think, but they're rugged as fuck and require 0 infrastructure to produce power. Most of the maintenance is wiping them with a damp sponge¹, and (these ghouls should love this part) zero non-maintenance labor to operate, no moving parts, and they work best during peak demand times, right? If I were powering my Last Redoubt, solar would be up there on my list of options until the sun dies.
