. Wind power currently produces about seven percent of Germany’s total electrical power. More than 21,607 wind turbines are located in the German federal area and the country has plans to build more wind turbines. As of 2011, Germany's federal government is working on a new plan for increasing renewable energy commercialization

Overview

As of 2010, Wind power in Germany provides over 96,100 people with jobs and German wind energy systems are also exported. The Fuhrländer Wind Turbine Laasow

Fuhrländer Wind Turbine Laasow is a wind turbine, built in 2006 near the village of Laasow, Brandenburg, Germany. It consists of a 160 metre lattice tower, which carries a rotor 90 metres in diameter. It is the tallest wind turbine in the world...

, built in 2006 near the village of Laasow, Brandenburg, is the tallest wind turbine in the world. Also most other of the tallest wind turbines in the world are situated in Germany, see List of wind turbines.

At Germany, there are also most of the most powerful wind turbines in the world, the Enercon E-126

The Enercon E-126 is the largest wind turbine model build to date, manufactured by the German wind turbine producer Enercon. With a hub height of , rotor diameter of and a total height of , this large model can generate up to of power per turbine. The nameplate capacity was changed from to ...

However, the economics of wind power in Germany are under close scrutiny and there are other issues which deserve consideration. These include the effect of wind turbines on the landscape, the effect on the bird population, and the effect on the tourist industry.

Repowering

Repowering
Repowering is the process of replacing older power stations with newer ones that either have a greater nameplate capacity or more efficiency which results in a net increase of power generated.-Wind power:...

, the replacement of first-generation wind turbines with modern multi-megawatt machines, is occurring in Germany. Modern turbines make better use of available wind energy and so more wind power can come from the same area of land. Modern turbines also offer much better grid integration since they use a connection method similar to conventional power plants.

Offshore wind power

Offshore wind energy also has great potential in Germany. Wind speed at sea is 70 to 100% higher than onshore and much more constant. A new generation of 5 MW or larger wind turbines which are capable of making full use of the potential of wind power at sea has already been developed and prototypes are available. This makes it possible to operate offshore wind farms in a cost-effective way once the usual initial difficulties of new technologies have been overcome.

On July 15 of 2009, the first offshore German windturbine completed construction. This turbine is the first of a total of 12 wind turbines for the alpha ventus

s will be erected far away from the coastlines, where the wind blows more consistently than it does on land, and where the enormous turbines won't bother the inhabitants. The plan aims to decrease Germany's dependence on energy derived from coal and nuclear power plants.
