Green Energy Investment Frenzy

July 2, 2008— -- Billions of dollars are being poured into turning things like algae, cooking oil, corn, cow manure and even tiny microbes in lab beakers, into new sources of fuel.

The United Nations dubbed this investment stampede a "Green Gold Rush," which has been sparked by soaring gas prices.

"There's certainly a gold rush of speculation, kind of like 1849, when everyone was rushing with their picks and shovels and finding opportunities," said Steve Jurvetson, managing director of Draper Fisher Jurvetson, a venture capital firm.

Last year, according to new numbers from the U.N. Environment Program, investors around the world poured $148 billion into alternative energy. That number is only growing as more companies become invovled in this research.

Companies are exploring a variety of well-known technologies. On the electric car front, Tesla Motors, a Sillicon-Valley company, and Norway-based Think have developed 100 percent electronic roadsters. Chevrolet, Volvo and other auto makers are working to create plug-in hybrids, and Tata Motors of India, and others, are creating cars that run on compressed air.

In addition to ventures into bio-safe corn-based fuel, developers are thinking outside the box. Companies like San Francisco-based LS9 are working at the frontier of microbe research, looking at microscopic bugs that eat things, like coal, sugar and wood, and turn it into natural gas or jet fuel.

However, these new technologies will most likely not come fast enough to relieve our current pain anytime soon.

Paul Saffo, a technology forecaster who documents long-term technological change, says there is "no easy, magic technological fix" to cure the pain Americans are feeling at the pump.

"This technology is definitely not going to arrive in time to save Americans' pocketbooks, but more importantly, it's not going to arrive in time to save American foreign policy," Saffo said.

Many experts believe inflation at the gas station is the best way to wean Americans off fossil fuels, which scientists believe are leading to potentially catastrophic climate change. While people suffering because of high gas prices may cringe, these experts embrace high gas prices as the surest way to spur energy innovation.
