• ### How To Calculate Power Output Of Wind Windpower Engineering

Jan 26, 2010 · Although 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 (kilowatthours [kWh]) is the quantity consumed.
