Solarpunk

Definitely second the /c/fiction recommendation but I'll also add for short stories that I've enjoyed these two magazines: https://reckoning.press/ and https://littlebluemarble.ca/

I've recently been reading The Terraformers, and have found an interesting mix of solarpunk ideals in the main characters and the set dressing, and some very cyberpunk stuff in the background of the planet and larger galactic society. So often genre is almost about what part of a setting you zoom in on and they're much more mingled so far than I'd expected here.

I'll also always recommend Ecotopia, if only because I don't see it pop up as often.
