I love solarpunk as an idea. I would love to live in a solarpunk utopia. My biggest problem is its lack of grounding in economics. It's obvious that the people producing solarpunk art and literature comes from a privileged Californian background where the temperature is always suitable for living outside without heating or AC and it's always sunny not too far from the equator and without too much natural disasters. The cost and efficiency of solar panels and wind turbines are never discussed nor compared; which any serious major engineering endeavor should do first to be taken seriously. I think a solarpunk type of society is possible only if the population live near the equator and has a high level of societal sophistication where most people have an engineering degree and contributes positively to advance and maintain a society with the efficiency needed where there is a lower economic availability of energy.
