As part of the energy shift, wind turbines are considered to be one of the primary pillars for achieving the climate goals of the Paris Agreement. Clean and CO2-neutral energy is generated by wind and fed into the public grid.

Apart from the mentioned point, through wind projects local communities are supported through business tax and compensatory measures are coordinated and implemented with the environmental authority. In addition, local residents benefit from increasing infrastructural measures, such as new access roads.

Actually not – we deliver electricity to the local grid for about 0.07 euros per kilowatt hour – an average electricity price costs 0.33 euros per kilowatt hour.

Wind energy is now so cheap that coal and nuclear power plants can no longer be operated competitively with wind energy, regardless of the politically determined abandonment.

As soon as tenders are announced by the authorities for areas suitable for wind farms, we examine the site with comprehensive expert reports. We assess the impact on the agricultural landscape, soil, animals and plants, and plan and implement compensatory and replacement measures in consultation with the environmental authority. The protection of nature has the highest priority in every wind farm project.

Vor dem Bau einer Windenergieanlage müssen die strengen Vorgaben, zur Schallemission z. B. „Technische Anleitung zum Schutz gegen Lärm“, eingehalten werden.

Eine Windenergieanlage hat, wenn man direkt davorsteht, einen Schallpegel von ca. 100 dB. Schallreduktion spielt eine zentrale Rolle beim Design unserer Anlagen beispielsweise durch schalloptimierten Rotorblätter, schallgedämmten Gondelinnenräume oder schallreduzierte Betriebsweisen.

Der Schall-Grenzwert z. B. in einem Wohngebiet liegt bei 35 dB. Die ankommenden Geräusche – der mehreren hundert Meter entfernten Windenergieanlagen – in einem Wohngebiet sind akustisch kaum wahrnehmbar und werden von Umgebungsgeräuschen, wie Bäume, Regen und Schneefall überlagert.

The potential danger to birds and flying objects in general is constant and does not change with the height of the wind turbine. In cooperation with nature conservation and the environmental authority, the projects are examined in detail and evaluated by an expert. The protection of nature has the highest priority in every wind farm project.

In general, a wind turbine is dismantled in the reverse order to its construction.

A large proportion of the components used can already be recycled and transferred to the recovery chain. This applies in particular to tower components and parts such as bearings, wind turbine blades, gearboxes and generators. Plant foundations are also broken up and separated into their steel and concrete components. Concrete can be recycled for new crane parking areas and access roads as part of Repower projects at the site.

The disposal or recycling of rotor blades is the biggest challenge today. Due to their low thermal value and their components, rotor blades are difficult to incinerate. Nevertheless, there are various approaches to dealing with old rotor blades. On one hand, blades are shredded, the shredded GRP is mixed with paper and fed into the cement industry as a product. Other processes are already being considered in the MV wind energy cluster. For example, there are considerations in the area of recycling, in which rotor blades are broken down into their raw materials (very energy-intensive). Other possibilities such as “upcycling” also provide ideas for using old rotor blades to make furniture, roofing or building materials, for example.

A wind turbine is considered to be an aeronautical obstruction for air traffic. Each wind turbine must be equipped with an aviation light from a total height of 100m. In order to increase acceptance among the population, the flashing of wind turbines at night has to be reduced to a minimum through the implementation of the demand-controlled night signalling (BNK).

A large part of the value chain of our wind turbines is located in Germany. As a result, we create numerous national jobs with our suppliers, transport companies, steel producers, management companies and many more.

In Germany as a whole, there are around 135,000 jobs in the wind industry.
