The American wind power industry grew at a blistering pace in 2009, adding 39 percent more capacity, according to an article in The New York Times today. The country is close to the point where 2 percent of its electricity will come from wind turbines, the article said. The Times pulled the data from the annual report of The American Wind Energy Association. That report said the amount of capacity added last year, 9,900 megawatts, was the largest on record, and was 18 percent above the capacity added in 2008, also a banner year.
