At Gerbach, there is the world's most powerful wind turbine, an Enercon E-126 with axis height of 135 metres and rotor diameter of 127 metres with a generation capacity of 7.5 MW. At the end of 2013, a rotor blade came loose and crashed to the ground. This was caused by several cracked bolts on the rotor blade attachment. In May 2014, the turbine was put back into operation after being repaired.
