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 using wind turbines, generally grouped into wind farms and connected to the electrical grid. In ...
Wind power
Wind power is a form of energy conversion in which turbines convert the kinetic energy of wind into mechanical or electrical energy that can be used for power . Wind power is considered a form of renewable energy. Modern commercial wind turbines produce electricity by using rotational energy to drive a generator.
Learn about wind energy, a form of renewable energy that harnesses the power of the wind to generate electricity. Find out how wind energy works, its benefits and impacts, and DOE's role in advancing wind energy technologies.

Wind Energy Factsheet
Wind Resources and PotentialApproximately 2% of solar energy striking Earth's surface is converted into kinetic energy in wind.1 Wind turbines convert this kinetic energy to electricity without emissions,1 and can be built onshore or offshore.2 Wind power is proportional to the cube of wind speed; high wind speeds yield more energy.4 Average annual wind speeds of 6.5 m/s or greater at 80m ...

Wind Power
Wind power is a "form of energy conversion in which turbines convert the kinetic energy of wind into mechanical or electrical energy that can be used for power ," according to Noelle Eckley Selin of the Massachusetts Institute of Technology. Wind is considered an alternative or renewable energy. [1]
A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.
Wind explained
Wind energy for electricity generation Today, wind energy is mainly used to generate electricity. Water-pumping windmills were once used throughout the United States, and some still operate on farms and ranches, mainly to supply water for livestock.
