Nep appears to be a fan of solarpunk. I enjoy it myself, but it comes with the problem of being conflict-free which makes it difficult to use as a setting for storytelling*. As a 'movement' (lol) it's hamstrung by the fact that no one really can figure out how to get from now to Harmonious Solarpunk Future where everyone's happy and healthy and living in balance with nature and each other. So much of the rationale for it from its proponents is 'Why can't you just believe something better is possible?' with no actual suggestions for the actual large-scale steps that could be taken. It's some serious head-in-the-clouds stuff, often pushed by people who would describe their political beliefs as Anarcho-Something, but it does have some very nice looking visual art.
*To the point where, despite solarpunk having been around for decades, there really are no great works of solarpunk fiction. In a bit of classic irony, the best-known piece of Solarpunk is 'Dear Alice', an animated commercial for Chobani yogurt. Utilizing the aesthetics and even elements of the ethos of an artstyle that is inherently anti-corporate in order to sell you something is exactly why cyberpunk is the SF subgenre with the best predictive power.
