Most German states have no interest in wind power minimum-distance rules
Bavaria is the only German state that made use of a law to set its own minimum distance for wind turbines from residential buildings, the German government has said in an answer to a parliamentary inquiry by the Free Democrats (FDP). The government says there is no indication that a minimum distance leads to greater acceptance of wind power among citizens, and says the visibility of turbines and involvement of citizens in the planning stages play a much greater role. The government says the states’ general construction regulations and the German immission protection law (BImschG) are sufficient to ensure “reasonable” distances.
