Clean-tech bubble? Just wait for the next president
While many people are looking for a single solution--the Bush administration has put all bets on ethanol, according to Tamminen--there should be much wider acceptance of approaches to climate issues.
"There is no silver bullet," he said. "All different technologies will be commercialized," from biodiesel made of algae to solar paint developed with nanotechnology. "I don't think we even have begun to scrape the surface of solar power."
Ultimately, Tamminen said, innovation will be driven by urgent needs.
"Climate policy is what's pushing those technologies out to the commercial forefront much faster," he said. "We will have periodic shortages of gasoline during the next few years, and when that happens, the person who invented how to get liquid motor fuel out of algae, out of agricultural waste, is going to look like a genius."
