the solarpunks are wrong, and you have to delude yourself pretty thoroughly to believe it's possible to have advanced manufacturing of semiconductors like microcontrollers for farming bots and batteries and, yes, solar panels, in a world where the evil polluting factories and mines that make those things are defunct and covered in vines, and in fact I'm pretty sure the whole aesthetic sprang from "i want evil pollution to end but i don't want to give up any of my modern technological conveniences" and then working backwards into a world where that's true, hand-waving all the details of where the technology comes from. but eh, let em have their fun. they're mostly young and they deserve to have a little hope that the future after capitalism burns itself out won't be natural disasters and 50C summers competing for who can kill the most people until there are none left
