An environmental activist holds two signs; "Mit 10H und blockade von Stromtrassenbau wird's verdammt schwer..." (English: "With 10H and a blockade of power line construction, it's going to be damn difficult") and "Hahahahahahahaha 10H is ein Witz" (English: 10H is a joke"). On January 20, 2022 the leader of the Green party Buendnis 90 / Die Gruenen, Vice Chancellor and Minister for Economy and Climate Protection Robert Habeck visited the Bavarian Minister President in the Bavarian State Chancellery in Munich, Germany. In front of it, environmental activists protested for wind energy and against the 10H-rule. The 10H-rule says that the distance between a wind turbine and houses has to be 10 times the height.
