A wind turbine harnesses wind energy by converting the kinetic energy obtained through the rotation of the blades into mechanical energy. It accomplishes this by using a system comprised of a generator, gears and shafts. By means of a network of transmission lines, the turbine sends electricity to the homes of consumers.
A wind turbine works in a way opposite to that of a fan. Whereas a ceiling fan uses electricity to rotate and make wind, a wind turbine takes the kinetic energy of wind and turns it into electricity. A wind turbine has assessment equipment that positions the blades in the optimal angle for wind capture. When wind blows, blade rotation triggers an internal shaft connected to a gearbox that, in turn, increases the rate of rotation and powers a generator that produces electricity.
As the wind turbine produces energy, it sends the electricity to a main power grid, from which smaller distribution lines deliver power to cities and homes.
There are wind turbine sizes adapted for both home and community use. Turbines below 100 kilowatts power homes, water pumping and telecommunications dishes, and they often form part of a hybrid system combined with diesel generators and batteries. Turbines for broader purposes can range from 100 kilowatts to as much as several megawatts.
