Alternative Energy Search Renewed

Fuel cells, solar power, wind power and other alternatives generally remain more costly than oil, gasoline and natural gas despite the recent increases in the price of crude oil and other fuels. Solar, wind and fuel cell markets grew from $9.5 billion in 2002 to more than $16 billion last year, according to Clean Edge, a San Francisco-based market research firm. The company expects the market for alternative energy to expand sixfold by 2014, to more than $100 billion.
