Wind Power Density (WPD) is a quantitative measure of wind energy available at any location. It is the mean annual power available per square meter of swept area of a turbine, and is calculated for different heights above ground. Calculation of wind power density includes the effect of wind velocity and air density.
e. Wind power is the use of wind energy to generate useful work. Historically, wind power was used by sails, windmills and windpumps, but today it is mostly used to generate electricity. This article deals only with wind power for electricity generation. Today, wind power is generated almost completely with wind turbines, generally grouped into ...

The Gansu Wind Farm in China is the largest wind farm in the world, with a target capacity of 20,000 MW by 2020. A wind farm or wind park, also called a wind power station or wind power plant, [1] is a group of wind turbines in the same location used to produce electricity. Wind farms vary in size from a small number of turbines to several ...
Floating wind turbine. The world's first full-scale floating wind turbine, the 2.3 MW Hywind, being assembled in the Åmøy Fjord near Stavanger, Norway in 2009, before deployment in the North Sea. A floating wind turbine is an offshore wind turbine mounted on a floating structure that allows the turbine to generate electricity in water depths ...
Wind-turbine aerodynamics. Wind-turbine blades awaiting installation in laydown yard. The primary application of wind turbines is to generate energy using the wind. Hence, the aerodynamics is a very important aspect of wind turbines. Like most machines, wind turbines come in many different types, all of them based on different energy extraction ...
