Abundant, renewable, and free, wind energy has been the fastest growing energy source since 1990. Installed wind turbines worldwide at the end of 2003 stands at over 40,000 MW, doubling since 1999, and ten times the 1994 total. Forecasts of global turbine sales in the coming years vary.

Growth of wind energy is being driven in large part by the commitment from many industrialized nations to reduce greenhouse gases. There is a discernable, growing public demand for green energy.

Without shortcomings or detractors, wind energy installations are clean, non-polluting, they consume no water, and leave no residual waste to dispose.
