2007 will go down as another record year for the wind energy industry, according to projections from the American Wind Energy Association (AWEA). The AWEA estimates the industry will install a record 3,000 MW of new wind power capacity in 2007 -- and for the first time produce enough total energy to supply more than 3 million American homes.

2007 was also a year of other important wind energy milestones. Texas surpassed California as the nation's largest generator of wind power and conventional oil and gas companies and Shell expanded into renewable wind energy.
