Wind Generators

Wind generators can be defined in two ways. The first is the more general use of the term, while the second is more specific. In the first case, a wind generator is defined as the entire device used to generate electricity from the wind. In this context, wind generators include the tower, the wind turbine, the blades, the gearbox, the internal generator for producing electricity, and the controls. The second definition includes only the device inside a wind turbine that is used to produce electricity. It is in this more specific sense that wind generators will be described herein.

A wind generator is similar to the alternator in your car. An alternator is used to generate electricity to charge the battery in your car. It must be driven by a belt that is powered by the car’s engine. In this same sense, a wind generator must be driven by the blades that are attached to the wind turbine. While the blades rotate in the wind, the wind generator rotates, producing electrical power. However, the blades do not rotate fast enough to drive the generator. A gearbox is used to increase the rotation obtained from the blades, so the wind generator can rotate fast enough to produce electricity. Using this method, wind generators have been used to generate electricity since the late 1800’s. Today’s modern wind generators are highly-engineered, technically-advanced systems for producing clean, efficient, renewable electrical power.

Wind is considered the fastest growing source of electricity in the world. It is often one of the least expensive forms of renewable power available. Some experts say it can sometimes be the cheapest form of any kind of power. Generating power from the wind leaves no harmful waste products behind. Best of all, its supply is considered unlimited, because the wind will blow as long as the sun shines. Electricity from wind generators is produced in quantity in wind farms.
