Nuclear efficiency
Nukes are marvelously efficient once they're up and running but people forget the huge energy expediture required to construct a plant. I heard a caller from the nuclear industry this morning on a radio talk show say that the payback in years for a plant is 15 years to recover the energy required for the plant construction. I don't have any independent confirmation of this claim but, knowing the huge energy requirements for uranium processing, and the stringent building codes required for the plants, it doesn't seem unreasonable.
I think we need nuclear power in our world but let's not get illusions that it's a cureall for our huge dependence on energy. It's just a piece of the puzzle.
