Funny. In renewable energy circles, the first, and most efficient, optimization is "conservation". Converting the 50 incandescent bulbs in your home to their LED or CFL counterparts yield more long-term value than spending the money on the ability to produce the power those original bulbs consumed.
Likewise, our government needs to quit pretending it actually needs money and cut spending. The TSA and middle-east war machines are the first places I'd start with.
