US wind energy installations now exceed 10,000MW in generating capacity.
The record growth in wind power is driven by demand for the popular energy source and concerns over fuel price volatility and supply. It was also made possible by a timely renewal of the production tax credit (PTC), a federal incentive extended in the Energy Policy Act signed a year ago by President Bush. Previously, the credit had been allowed to expire three times in seven years, and this uncertainty discouraged investment in wind turbine manufacturing in the country. AWEA is calling for a long-term extension of the PTC before its scheduled expiration at the end of 2007 to avoid further “on-again-off-again”cycles and encourage long-term investment.
