I love the aesthetic and ideas, but personally I couldn't get into it that much. It ~~seems~~ feels too unrealistic and a little like greenwashing (renewable energy and other high-tech is core to the ideology).
A book featuring the style which I really liked was A Psalm for the Wild-Built.
Sorry, I used the wrong wording. I meant to write that it feels a little like greenwashing to me, because I don't have a lot of faith in a "green transition" (not enough materials, exploitation of the global south etc...). But the good thing is that the solarpunk vision can work just as well in a low-tech environment.
