In Mecklenburg-Western Pomerania, a developer who builds a new wind farm must offer at least 20 percent of the project company to its neighbors. People who live within five kilometers may buy shares, and so may the nearby municipalities. The stated purpose of the law is to improve acceptance of new wind turbines. A developer challenged the law. In a decision of 23 March 2022 the Federal Constitutional Court found it almost entirely compatible with the Basic Law. The court accepted the legislature’s premise that acceptance of wind farms is especially high when they are run by a local company unter bürgerschaftlicher und kommunaler Mitverantwortung, with shared responsibility of citizens and municipalities.
