Learn about powering your home with wind energy. . Search for power developed by wind turbine in the English version of Wikipedia. Wikipedia is a free online ecyclopedia and is the largest and most popular general reference work on the internet. The area is in meters squared, air density is in kilograms per meters cubed and wind speed is in meters per second. Power output is calculated as follows: \text {power}=\frac {\text {air density}\times \text {swept area of blades}\times \text {wind speed}^3} {2} power = 2air density×swept area of blades×wind speed3. Most turbines automatically shut down when wind speeds reach about kilometers per hour (55 miles per hour) to prevent mechanical damage. Most wind turbines are made up of rotor-mounted blades that resemble airplane propellers. When air blows through them, they cause the rotor to turn a shaft that powers an electrical generator. In , 16 countries generated a total of about billion kWh of wind . Aug 25, · China has invested heavily in wind energy and is now the world's largest wind electricity generator.
