You’re wrong on this point. Without heavy subsidies it’s not cheaper yet. (Won’t be for some time) And countries like the US and can afford that, but what happens in India? Or how about when Africa starts industrializing? What we do here in the US and Europe (China is a joke) won’t do anything to slow the warming that will be caused by that. I’m not saying to be irresponsible with the environment, I’m saying the money being subsidized would be best spent relocating people, infrastructure improvements like flood control for NYC harbor, and investments in fission and fusion power.
