We could probably get it going here in Australia. We’ve got an awful lot of land not good for much other than solar arrays. We may need them to run desalination once all our natural water sources dry up. We already have communities living underground.
I'd love to think so, but I'm struggling to imagine what could initiate that sort of cultural change in the rural communities responsible for food production since the referendum has shown that the sorts of attitudes needed for a solarpunk society is missing from a lot of those areas. I'm sure climate change will soon make sustainability a priority for rural areas but that alone won't change most of the other values
