The document provides an overview of wind turbine engineering. It discusses that wind power depends on air volume, velocity, mass, and flux. Kinetic energy and power from wind is calculated using formulas involving air density, velocity, and swept area. The Betz limit establishes that a conventional wind turbine can extract up to 59% of the power contained in wind. Power output is proportional to the cube of wind velocity, air density, and swept area. A capacity factor of around 30% represents the fraction of time a turbine operates at its rated power level based on turbine and site characteristics. Wind turbines have subsystems including foundations, towers, nacelles, hubs, drivetrains, generators, and controls. Design considerations include aer
