Nuclear power
The USA was once in the forefront of nuclear physics. The proof lies in part in these names: americium, californium, berkelium, lawrencium, seaborgium. Einstein was a citizen too, but I won't claim einsteinium for the USA.
We liberals should be proud of this, in spite of the bombing of Nagasaki (there is a grain of an excuse for Hiro-shima, so long as you don't call the place Hi ROSH ima). But more to the point, the reason there's a problem when a few nuke plants are off line is that they quietly and with astonishingly little pollution deliver twice as much electricity as the only really productive and reliable solar-origin technology, the big, mostly government owned hydroelectric plants.
The USA has a tested design for a meltdown-proof, terrorist-proof, renewable and sustainable nuclear breeder reactor that needs so little fuel to produce a gigawatt.year of electricity that if it were government owned, it could probably pay off the national debt by charging $0.08 per kWh. Our present reactors, by EIA data, run at 90% of 24/7, higher than any other technology.
