Small wind turbines defined as having rated capacities of 100 kilowatts and less. They are electric generators that utilize wind energy to produce clean, emissions-free power for individual homes, farms, and small businesses. Small wind turbines can help individuals generate their own power, cutting their energy bills while helping to protect the environment. In some cases, excess energy can be sold back to the grid (for more information, see our section on Interconnection & Net Metering).
According to a study conducted by American Wind Energy Association (AWEA), in 2008 the U.S. small wind market grew up 78% for wind turbines with a capacity of 100 kW, with an additional 17.3 MW of installed capacity. The rise in the small wind market cab be attributed to increased private investment which gave boost to manufacturing volumes benefiting the commercial segment of the market (systems 21-100 kW). However, this is not the only market to benefit from the investment, and manufacturing economics of scale. This also drove growth in the residential market (1-10 kW). The residential market was also driven by rising residential electricity prices and a heightened public awareness of wind energy.
AWEA’s study also found that U.S. Manufacturers sold approximately half of all small wind turbines installed worldwide later year. The U.S. market share accounted for $77 million of the $156 million global total.
