Not too expensive - too risky.Power stations are usually coal or nuclear. Switch to nuclear. Easy option. Is it too expensive, fellow republicans?
We have too many farking lawyers in the USA, especially in government. Shakespeare was right.
Exposure to lawsuits from the environmental slip/trip & fall shysters makes financing and insurance unobtainable on the scale we need to save the planet from planetary heat death.
Government needs to chivvy the f**king lawyers out of the building and do something truly useful for once, by stepping up and underwriting the extreme "tail" of nuclear risk exposure, i.e., the extremely unlikely events. Doesn't cost government a nickel - just the ink for signatures. This puts commercial power producers in a position to raise finding and obtain insurance on a normal commercial basis for nuclear plants.
Hit the "Easy" button - problem solved, and planet saved.
