Wind Power

We have been harnessing the wind's energy for hundreds of years. A wind turbine - It can use the wind's energy to generate electricity.

Wind turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or above from ground level, they can take advantage of the faster and less turbulent wind. Turbines catch the wind's energy with their propeller( blades). Mostly, three blades are mounted on a shaft to form a rotor.

When the wind blows, a pocket of low-pressure air forms on the downwind side of the blade. The low-pressure air pocket then pulls the blade toward it, causing the rotor to turn is known as lift. The force of the lift is actually much stronger than the wind's force against the front side of the blade, which is known as drag. The combination of lift and drag causes the rotor to spin like a propeller, and the turning shaft spins a generator to make electricity.

Wind turbines can be used as stand-alone applications, or they can be connected to a utility power grid or even combined with a solar cell system. For utility-scale sources of wind energy, a large number of wind turbines are usually built close together to form a wind plant.

The home owners & farmers in windy areas can use wind turbines as a way to reduce their electric bills.

Small wind systems also have potential as distributed energy resources. Distributed energy resources refer to a variety of small, modular power-generating technologies that can be combined to improve the operation of the electricity delivery system.
