Energy is captured from wind through the phenomenon of lift — the same phenomenon that allows birds and airplanes to fly. (Turbine blades are, in essence, captive wings.)
READ MOREWind turbines produce varying amounts of energy depending on a wide range of factors. Some of the largest wind turbines can produce up to 12 MW of electricity. This is enough to power to around 16,000 households per turbine each year. A good residential wind turbine should have a rated power output of between 2 kW and 10 kW.
READ MOREWind speed largely determines the amount of electricity generated by a turbine. Higher wind speeds generate more power because stronger winds allow the blades to rotate faster. Faster rotation translates to more mechanical power and more electrical power from the generator.The relationship between wind speed and power for a typical wind turbine is

READ MOREAlthough the calculation of wind power illustrates important features about wind turbines, the best measure of wind turbine performance is annual energy output. The difference between power and energy is that power (kilowatts [kW]) is the rate at which electricity is consumed while energy (kilowatt-hours [kWh]) is the quantity consumed.

Conservation of mass requires that the mass of air entering and exiting a turbine must be equal. Likewise, the conservation of energy requires the energy given to the turbine from incoming wind to be equal to that of the combination of the energy in the outgoing wind and the energy converted to electrical energy. Since outgoing wind will still possess some kinetic energy, there must be a maximum proportion of the input energy that is available to be converted to electrical energy. Ac
