There are 30,000 wind turbines in operation in Germany, many of which are starting to age. In 2019, 2000 rotor blades had to be discarded; in 2024, this figure will shoot up to 15,000. But where to put these up to 90-meter-long, ...

In very cold climate zones, the wind can blow with tremendous force. But wind turbines have rarely been built in these regions up to now. The risk of ice formation on the rotor blades is just too high. But now, an energy-efficient ...
