I have to say, solarpunk has always seemed like a silly concept. Where's windpunk in this picture? The long-term energy picture for civilization ultimately has to embrace the closed-loop model, in which exhaustible resources - ancient deposits of fossil fuels and uranium ore - are not the basis of the energy supply. In that situation, there are really only about two plausible energy sources: inputs from the local gravitationally contained fusion reactor, aka "the Sun", in the form of sunlight and wind, and geothermal inputs from the hot interior of the Earth. Utilizing such energy sources over the long term has several constraints: you want to stabilize the chemical composition of the atmosphere, to avoid things like runaway heating or cooling, you want to ensure that soil - in which food grows - is stable and not polluted, you want to ensure that fresh water is available, you want to avoid stripping all the oxygen out of the ocean, and of course, this all means stabilizing the human population on the planet at a level that makes all this possible over the long run. And, leave enough of the planet's wilderness around to support biological diversity, that seems important too. Maybe we call it 'steady-state-closed-system-sustainable-with-room-for-other-species-punk'...
