While the oil companies claim that wind and solar power are simply not "economic," the market continues to prove them wrong:

The United States passed Germany to become world #1 in wind power installations, and China’s total capacity doubled for the fourth year in a row. Total worldwide installations in 2008 were more than 27,000 MW, dominated by the three main markets in Europe, North America and Asia.

Global wind energy capacity grew by 28.8% last year, even higher than the average over the past decade, to reach total global installations of more than 120.8 GW at the end of 2008. Over 27 GW of new wind power generation capacity came online in 2008, 36% more than in 2007.

The excuses for avoiding renewable energy keep falling apart, don't they?
