Things that are solarpunk: building tall, building dense, building multi-use. The more you limit your building footprint, the more space you have for farms and gardens and wild green spaces. A single 100-unit apartment complex, with a shuttle bus to the local train station, is roughly a hundred times more efficient than a subdivision with 100 single family homes and probably 200 cars.

People hate to hear it, but the American style of private home ownership ain't solarpunk, or socialist, or any other brand of leftist. It's pretty much the most capitalist thing a member of the working class will ever do.
