Wind energy, or wind power, is created using a wind turbine, a device that channels the power of the wind to generate electricity. . Wind is caused by uneven heating of the earth's surface by the sun. As renewable energy technology continues to advance and grow in popularity, wind farms like this one have become an increasingly common sight along hills. . Where are wind farms usually built, and why? What are some benefits and challenges of using wind power for energy? wind power, 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 turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. By orienting an airplane wing so that it deflects air downward, a pressure difference is created that causes lift. Wind turns the propeller-like blades of a turbine around a rotor, which spins a generator, which creates electricity. Wind is a form of solar energy caused by a. . Each wind turbine stands tall, separated from its neighbors by several hundred meters or more. In some cases other infrastructure (oil and gas wells, for example) shares the land. They're serving a very useful purpose, however.
