The less realistic version I might put in a story rather than propose as a legitimate plan for society would be the reclamation of components from ewaste. Our society has produced and discarded vast quantities of electronics. In a setting where production has been pared back, either by collapse (environmental or societal) or societal will, I could see masses of ewaste becoming almost a resource to be harvested, future generations hopefully putting the surviving parts to a more careful, long-lasting use.

The capability (skillets, industrial knowhow, manufacturing capabilities) would need to be maintained, but production could be slowed (and probably would if, as poVoq said, more environmentally-sane production methods were implemented). There’s a balance to walk there, between a society living off its stored fat, forgetting how to make the things it relies on, and our current model of unsustainable infinite growth.

The sourcing of those reclaimed components is also ripe for exploitation and wasteful/environmentally-destructive industry - it’s easy to picture it looking more like the sweatshop from the second blade runner movie than the kind of careful, deliberate co-ops a solarpunk society would hopefully emphasize.
