Carter formed the DOE by combining the Nuclear Regulatory Commission, the Energy Research and Development Administration, the Federal Energy Administration, the Federal Power Commission and some others. I'm not sure if that re-organization actually made gov't bigger or smaller.

I think I read that the head of the Sierra Club is now in favor of nuclear power as he should be. It is about the greenest source of power there is.
I was reading there are new designs (fast sulfur reactors) that consume used fuel rods reducing them in size and energy. Great idea! Existing plants only use %5 of the energy in the rods so there is plenty left. Since Nevada doesn't want them in Yucca mountain they are filling up temporary storage. BTW I can't think of a better place for nuclear waste than Yucca mountain. I've been there.
We need to start building lots of nuclear units and now. But it will take years and years, probably decades to build many more. We still have over 100 units which produce about %19 of US electricity (%8 of our energy). Licenses for 5 more units are being worked on, these are new designs of old technology. We need to build about 300 more units. Even if we do that we still need a full build out of natural gas to power our vehicles. If we abandon natural gas and go all electric vehicles we need to build maybe 900 nuclear units.
