Before the virtual general meeting of the energy company Uniper, Greenpeace activists protest with a motorised paraglider against the planned coal-fired power station Datteln 4 on 20 May 2020. Uniper wants to put the coal-fired power station into operation in summer 2020. During the half-hour flight around the power plant, the climate protection activists demanded on a 12 square meter banner: "Uniper - Stop Datteln 4!".
