Solar has gotten cheaper and cheaper largely because as we build more panels and batteries, we find efficiencies. If we had accelerated our transition then the increased demand would have driven even more efficiencies and it would be even cheaper it is now. If it were cheaper, developing countries would buy even more of it, accelerating their own transition.
