![]() These blades are usually made of a composite material, such as fiberglass. Most small wind turbines manufactured today are horizontal-axis, upwind machines that have two or three blades. In addition to the turbine and tower, small wind electric systems also require balance-of-system components. Small Wind Electric System ComponentsĪ wind electric system is made up of a wind turbine mounted on a tower to provide better access to stronger winds. This makes small wind electric systems a good choice for rural areas that are not already connected to the electric grid. Our wind power animation has more information about how wind systems work and the benefits they provide.Ī small wind system can be connected to the electric grid through your power provider or it can stand alone (off-grid). When the wind spins the wind turbine's blades, a rotor captures the kinetic energy of the wind and converts it into rotary motion to drive the generator. Wind turbines convert the kinetic energy in wind into clean electricity. Wind is created by the unequal heating of Earth's surface by the sun. Our pages on planning for a small wind electric system, and on installing and maintaining a small wind electric system have more information. ![]() ![]() Small wind electric systems can also be used for a variety of other applications, including water pumping on farms and ranches.
