Wind is probably the most powerful natural force in the world - and therefore also a powerful source of climate-friendly energy. The principle: gusts of wind set the three rotor blades in motion, which in turn drive a generator whose electricity is fed directly into the grid. Today's wind turbines often reach over 100 meters into the sky, and depending on the diameter of the rotors, total heights of 200 meters can occur.
Over the past two decades, wind power has developed into the most cost-effective renewable energy source. In addition to the number of wind turbines, the performance of the individual turbines has increased massively. Whereas in the 1990s turbines with an output of 600 KW were standard, today's top turbines are 7.5 MW. Most of the wind energy produced today still comes from onshore wind farms, but more and more powerful offshore wind farms are being connected to the grid. They have a higher acceptance among the population and a better wind yield, because on the open sea the winds blow stronger and more evenly.
