@thisfro - Yeah! That's solarpunk! 😂 Degrowth, mutual aid, decentralized and localized economies, anti-capitalism, social justice, ethical and thoughtful approach to technology, climate and ecological sustainability, etc et al. What you're describing is solarpunk.
@LibertyLizard - I think it was a bit the other way round. Solarpunk started as an idea. Just the "I'm tired of dystopian scifi. I want utopias that address pragmatic concerns and show us a way out of this current situation."
Then folks started to collate ideas on how to make that work and found that various anarchic philosophies already addressed it.
@AEMarling - Cheers! Just put it in! (Screenshot of request below... but not sure if you can see it in the Lemmy UI - You'll have to click on this reply's link to view it on the Mastodon page for the screenshot)
