The barriers that renewables and efficiency face come less from our living in a capitalist market economy and more from not taking market economics seriously.

Fire made us human, fossil fuels made us modern, but now we need a new fire that makes us safe, secure, healthy and durable.

Economies are supposed to serve human ends.. not the other way round. We forget at our peril that markets make a good servant, a bad master and a worse religion.

The reason the U.S. lags so badly is that we have obsolete rules that favor big over small, supply over efficiency, and incumbents over new market entrants.

If you ask me, it'd be little short of disastrous for us to discover a source of clean, cheap, abundant energy because of what we would do with it.

Prominent exploration experts have recently predicted that total world production of liquid oil will peak by about the end of this decade-or a few years later if production does not rise much-and will decline thereafter.

We'd find more energy in the attics of American homes (through energy conservation measures) than in all the oil buried in Alaska.
