The American Wind Energy Association (AWEA) reports that the U.S. market for small wind turbines – 
those with capacities of 100 kilowatts (kW) and less – grew 78% in 2008, with a total of 17.3 megawatts (MW) of new installed capacity, offering new evidence that consumer demand for clean energy options is on the rise.
"The U.S. wind industry is a growing bright spot in our domestic economy, and the small wind sector is no exception," said AWEA CEO Denise Bode. "Strong federal policies like the federal investment tax credit for small wind are critical to future growth, just as adoption of a federal renewable electricity standard (RES) is essential to growth in the utility-scale market."
U.S. manufacturers sold about half of all small wind turbines installed worldwide last year. U.S. market share amounted to $77 million of the $156 million global total. (Worldwide, about 38.7 MW of new small wind capacity was installed in 2008.)
Growth in the small wind sector is largely attributable to increased private investment that has allowed manufacturing volumes to increase, particularly for the commercial segment of the market (systems 21-100 kW). The still-largest segment of the market, residential (1-10 kW), was likewise driven by investment and manufacturing economies of scale, but also rising residential electricity prices and a heightened public awareness of the technology and its attributes.
