I must say that I am a bit (just a bit) sick of the solarpunk staple images of "it is a city but it is sunny and there are plants". I am a hard tech enthusiast, I do enjoy artificial settings and clean air, I think that painting enclosed spaces as gray and dimly light by monochromatic neon is as biased as depicting a city that's always sunny.
I want to live in a clean, sterilized, controlled environment, which does not have to be sad, which does not have to be unsustainable or oppressive, that's a matter of personal preference. I don't have allergies so I enjoy a hike in the forest or a picnic under the cherry blossom, but I'd prefer to have my indoors free from bugs, dust and pollen.
To me solarpunk is not about ecology, that's about a utopian future. One where you can choose to live closer to nature, like many current city dwellers would love, but these world are so much more than that!
