This article presents the basic concepts of wind energy and deals with the physics and mechanics of operation. It describes the conversion of wind energy into the rotation of a turbine, and the critical parameters governing the eﬃciency of this conversion. After that it presents an overview of the various parts and component of windmills. The connection to the electrical grid, the world status of wind energy use for electricity production, the cost situation and research and development needs are further aspects which will be considered.
