Wind energy

Østerild, Denmark: The energy yield of a wind turbine depends on such things as how much area a rotor covers. The picture shows the world’s longest rotor blade, 75 m, being mounted onto the hub of an offshore wind power plant. The 154 m rotor covers an area of 18,600 m² – as large as two football pitches. The system can produce 25 GWh of clean electric power per year on offshore sites. This is enough to supply 6,000 households. More than three decades of technical expertise went into the development of the gearless 6 MW system and the 75 m rotor blade.

The use of wind energy to generate electricity is among the most widely developed and most used renewable energy technologies, and is on the increase in more and more countries. Because of the economies of scale resulting from falling system costs in production and project development and the high natural potential, wind energy is becoming economically viable in more and more countries.

A distinction is made in the wind energy sector between onshore and offshore and small wind turbines. Onshore wind energy will become increasingly important in terms of system stability in the medium term. But even offshore wind energy will be able to contribute to the basic supply given the constant wind speeds and high capacity utilisation at sea.

German companies are among the leading providers in the wind sector. The range of services offered by Germany covers research, production of all types of components and complete systems, project development, and the maintenance and operational management of wind farms. Wind energy products and services “Made in Germany” enjoy an excellent reputation worldwide because of their reliability and their high level of technological development.
