Solar power edges towards boom time
Solar power could be the world's number one electricity source by the end of the century, but until now its role has been negligible as producers wait for price parity with fossil fuels, industry leaders say.
Once the choice only of idealists who put the environment before economics, production of solar panels will double both next year and in 2009, according to U.S. investment bank Jefferies Group Inc, driven by government support especially in Germany and Japan.
Similar support in Spain, Italy and Greece is now driving growth in southern Europe as governments turn to the sun as a weapon both against climate change and energy dependence.
Subsidies are needed because solar is still more expensive than conventional power sources like coal, but costs are dropping by around 5 percent a year and "grid parity", without subsidies, is already a reality in parts of California.
Very sunny countries could reach that breakeven in five years or so, and even cloudy Britain by 2020.
"At that point you can expect pretty much unbounded growth," General Electric Co's Chief Engineer Jim Lyons told the Jefferies conference in London on Thursday, referring to price parity in sunny parts of the United States by around 2015.
"The solar industry will eventually be bigger than wind."
The United States' second largest company, GE is a big manufacturer of wind turbines and wants to catch up in solar, said Lyons. ( Reuters )
