“Solarpunk” is a loosely defined subgenre of science fiction that attempts to envision non-dystopian futures. The most interesting examples of solarpunk writing focus on sustainable technologies, multiculturalism and post-capitalism, though the term has been widely appropriated for marketing purposes by proponents of hyper-technological architecture and questionable technologies such as cryptocurrencies, which are very much at odds with the intents and ideals that spurred the solarpunk movement.
My personal interpretation of solarpunk features a world populated by anthropomorphic animals with a technology level just a few years ahead of our own. I assume their world has many of the same issues as ours, such as global warming and overcrowding, but very different social norms, such as universal naturism, different species living transparently along each other (but having less cultural variety compared to human societies) and a prevalence of communal living arrangements.
