Wind power - Wikipedia
WEBWind 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 ...
Advantages and Challenges of Wind Energy
WEB—equivalent to the emissions from 73 million cars. Wind power benefits local communities. Wind projects deliver an estimated $2 billion. in state and local tax payments and land-lease payments each year.
How Do Wind Turbines Work? | Department of Energy
WEBThe terms "wind energy" and "wind power" both describe the process by which the wind is used to generate mechanical power or electricity. This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity.
Wind Energy Basics - Department of Energy
WEBWind energy is actually a byproduct of the sun. The sun’s uneven heating of the atmosphere, the earth’s irregular surfaces (mountains and valleys), and the planet's revolution around the sun all combine to create wind. Since wind is in plentiful supply, it’s a sustainable resource for as long as the sun’s rays heat the planet.
