Do you understand that foregoing the use of the most economical source of energy creates a relative disadvantage to the on doing the foregoing? So let’s say the entire world except for the U.S. manages to quit using the most economical source of energy and in its place uses less economical alternatives (if it requires subsidies it is less economical). The U.S. would then be left as the sole consumer of the most economical fom of energy which is getting even more economical since no one else is using it. The result would be world dominance. We can only hope the rest of the world is so stupid.
Of course the U.S. is right behind Germany and France in Stupid.
You are dead right that neither fuel cells or electric cars are as economical as gasoline right now. Nevertheless the world will keep pushing them until their price/performance reaches parity or better with internal combustion engine cars. Even before this happens a massive competition will break out between these competitive systems which over time will collapse the price of energy and transportation for all energy/transport systems.
You have described a beautiful thing.
