Wind power is one of the oldest forms of energy used by man. Windmills have been used for centuries to make mechanical work easier. In the 19th century, the first attempts were made to convert the mechanical energy into electrical energy. The advance of wind power began with the progress in technology, the increasing demand for energy and growing awareness for the environment.

The largest wind turbines we use in our planning now achieve an output of 3 to 7.5 MW and have a rotor diameter of 80 to 141 metres. In addition to continuous output monitoring and control, the wind turbines have early fault detection and systems for lightning protection and are usually located in wind farms. While individual wind turbines were often operated in the past, most wind turbines are now combined in wind farms so that synergy effects can be generated with regard to grid feed-in and maintenance work. The landscape is also less affected by the large state-of-the-art wind turbines in wind farms as individual locations are better utilized so that other areas can remain free. In addition, the areas around the wind turbine continue to be available to agriculture or nature.
