Wind turbines are electric generators that harness the wind to produce clean, emissions free power for individual homes and small businesses. With this simple and increasingly popular technology, individuals can generate their own power and cut their energy bills while helping to protect the environment.
Wind turbines have rotating blades that convert the winds kinetic energy into rotational momentum in a shaft. The rotating shaft turns an alternator, which makes electricity. This electricity is transmitted through wiring down the tower to an inverter which converts the direct current (DC) into alternating current (AC). The alternating current then flows into the electric panel for user consumption. In a grid connected system, excess electricity will spin your meter backwards and the utility company will credit you for the excess power generated. In an off-grid system, the power will be stored in a battery bank which supplies the home with power and charges the battery bank until full. The battery bank will supply the home with power when the wind energy system is not producing electricity.
Newer technology allows the blades to turn to face the wind allowing the wind turbine to track the winds as they shift direction. The tail directs the rotor into the wind.
