Wind power generation is power generation that converts wind energy into electric energy. The wind generating set absorbs wind energy with a specially designed blade and converts wind energy to mechanical energy, which further drives the generator rotating and realizes conversion of wind energy to electric energy.
Commercially available wind turbines range between 5 kW for small residential turbines and 5 MW for large scale utilities. Wind turbines are 20% to 40% efficient at converting wind into energy. The typical life span of a wind turbine is 20 years, with routine maintenance required every six months.
When operating at design wind speeds of over 12 mph, the five 1.5 MW wind turbines at this facility are capable of producing up to 7.5 MW of electrical energy. Since this is much more than the average 2.5 MW of power needed each day by this facility, the remaining energy is sold to the local power grid.
Wind electricity generation has grown significantly in the past 30 years. Advances in wind-energy technology have decreased the cost of wind electricity generation. Government requirements and financial incentives for renewable energy in the United States and in other countries have contributed to growth in wind power.
