Sustainability requires that we demand enduring quality. Steve Strong has a slide presentation pointing out that much of Oxford was built 800 years ago. What are we building today that will be here 800 years from now? If something like that emerged from this recession, it would help justify the hardship so many people are currently experiencing.

Under communism, prices were not allowed to reflect economic reality. Under capitalism, prices don't reflect ecological reality. In the long run, the capitalist flaw -- if uncorrected -- may prove to be the more catastrophic.

We need a firm cap on carbon emissions from fossil fuels. No coal, oil, or gas could enter the economy until the buyer had a permit. All permits would be auctioned by the federal government, and the number of permits auctioned would be decreased by three percent per year. Permits could be traded, but they could not be created out of whole cloth by companies that plant forests or dump iron filings at sea.

We presently have the technology ... fuel cells, solar cells, hydrogen ... the opportunities are amazing for clean energy.

Our goal is to turn solar electric technologies into a commodity business like computer chips, and make them ubiquitous in the built environment. I'd couple this with a huge commitment to fundamental research in nanostructure to goose the next generation of more efficient, cheaper, dematerialized cells. And if I'm truly czar, I'd emphasize silicon technologies, as that approach is the one least likely to encounter material constraints in supplying an explosive global demand.

The sunshine that strikes American roads each year contains more energy than all the fossil fuels used by the entire world.

Listen up, you couch potatoes: each recycled beer can saves enough electricity to run a television for three hours.
