That's why--given the scenario above-- the quickest and cleanest transition is to nuclear and natural gas as the back up. This gets you to liquid hydrogen or ammonia as the portable fuel in a fuel cell and eliminates fossil fuels as the basis for transportation and vehicles.
It continues as a legacy as the conversion is made making this both fast and economical.
Going to wind and solar, as Germany has proven, is a fool's errand and eliminating nuclear is just plain stupid. So, why are government's doing stupid? Well, we know the answer...
They are full of idiots, morons, retards, and technical illiterates. Garbage disposal anyone?
