I have little original to add here, but I wanted to call your attention to the article "Is Ornamenting Solar Panels a Crime?" by Elvia Wilk, which describes the Solarpunk movement, because it's wonderful and you should read it.
What is Solarpunk? It's derived from Steampunk and Cyberpunk, but oriented to clean energy. Wilk, in the link above, explains the Solarpunk philosophy:
"In its willful naiveté, this ornamented vision is inflected with nostalgia for an imaginary, bygone time when tech was tinkerable and free from mass production and standardization."
In its imagery, the Solarpunk movement includes a strong Art Nouveau influence, which to me feels right, right now. (See also: Art Nouveau and Modernisme)
Additionally, last month Rhys Williams emphasized the literary side of the movement in "Solarpunk: Against a Shitty Future," for the Los Angeles Review of Books. He wrote:
"Why is this genre promising? Because in Solarpunk, energy is explicitly political....
Solar energy provides a fruitful and flexible ground in the imaginary for experiments in being human and being social while it also preserves the ecological boundary conditions of our own existence. And that is the root of Solarpunk: an energy culture that serves as a platform for experiments in being, rather than a closure of it."
I would add: there are wonderful affinities between today's Solarpunks and the future-thinking tinkerers of the 1960s like Peter van Dresser, who are called "Creative Activists" and featured in Chapter 10 of The Solar House. van Dresser (who wrote some science fiction) called for "a decentralized, biotechnic society" which would represent "revulsion against the Establishment" (link). Here's how van Dresser described himself on the back cover of his book A Landscape for Humans (1976):
Hey Solarpunks: there's more! I think you'd like The Solar House.
