90s iteration is solarpunk or hopepunk, no? I have read no solarpunk books, but the description fits. The premise that we can captian planet / recycle our way out of the impending climate doom that corps and govs have inflicted on us.
At this point, Solarpunk has barely - if at all - escaped the aesthetic stage to produce any meaningful narrative works. Feels relevant that its origin story is tightly associated with a Chobani advertisement.
