   The elephant in the room to answer the 'why' is that fossil fuels were already working and it took vision to see beyond them and the massive subsidies they get. When vision was available (Jimmy Carter and solar panels on the White House comes to mind) the people without vision, or people that understood how to make a buck today at the expense of tomorrow, put up roadblocks (Regan tearing them down...). The technology, because it is massively better, eventually caught up and passed fossil fuels (yes I am talking in the past tense) which has finally made it easy to see even without vision and finally made it able for people to make a buck today. Nothing has structurally changed that would have allowed us to make different choices in the 70s. We are only, finally, now seeing the solar wave because the same forces are at play now as then. This means we haven't learned anything and will do (are doing?) this again with other technologies and issues.

The real question we should be asking ourselves is how to prevent this disastrous pattern from happening again and again. There is no point moaning that solar took so long to happen and there isn't a point to blaming 'big oil' since they will soon be replaced with ? (Big Tech? Big Solar? Big Ag? Big Space?). What are -actual- concrete changes can be made to avoid this type of mess in the future?
