A wind turbine, or alternatively referred to as a wind energy converter, is a device that converts the wind's kinetic energy into electrical energy. Wind turbines are manufactured in a wide range of vertical and horizontal axis. The smallest turbines are used for applications such as battery charging for auxiliary power for boats or caravansor to power traffic warning signs. Larger turbines can be used for making contributions to a dom

Wind Turbine Background A wind turbine is a machine that converts the wind's kinetic energy into rotary mechanical energy, which is then used to do work. In more advanced models, the rotational energy is converted into electricity, the most versatile form of energy, by using a generator.

A wind power class of 3 or above (equivalent to a wind power density of 150–200 watts per square metre, or a mean wind of 5.1–5.6 metres per second [11.4–12.5 miles per hour]) is suitable for utility-scale wind power generation, although some suitable sites may also be found in areas of classes 1 and 2.

Wind power or wind energy is the use of wind to provide the mechanical power through wind turbines to turn electric generators and traditionally to do other work, like milling or pumping. Wind power is a sustainable and renewable energy, and has a much smaller impact on the environment compared to burning fossil fuels. Wind farms consist of many individual wind turbines, which are connected to the electric power tr

HistoryTypes of TurbinesResourcesKey TermsThe idea of using naturally moving water or air to help do work is an ancient one. Waterwheels and windmills are the best examples of ancient mankind's ability to capture some of nature's energy and put it to work. The Romans were grinding corn with a waterwheelas early as 70 b.c., and modern-type windmills were being used in Persia around a.d. 700. Both are ancestors of the turbine. Both have large surfaces (paddles, buckets, or a sail) at their wheel edges that are stru
