A wind turbine is a device that harnesses the power of wind to generate electricity. It consists of blades that rotate when wind blows, which turns a rotor that is connected to a generator. The generator then converts the mechanical energy into electrical energy that can be used to power homes and businesses.

Wind turbines come in various sizes, ranging from small turbines suitable for residential use, to large turbines used in wind farms to generate electricity on a commercial scale. The output of a wind turbine depends on a number of factors, including wind speed, blade length, and the design of the turbine. They have a number of advantages, including being a clean and renewable source of energy, reducing dependence on fossil fuels, and helping to mitigate climate change. However, they also have some drawbacks, such as being dependent on consistent wind speeds and the need for careful site selection to minimize impact on wildlife and surrounding communities. Overall, wind turbines offer a promising source of renewable energy and are becoming an increasingly important part of the global energy mix.
