Greenpeace activists project a message onto the 180-meter-high cooling tower of the Datteln 4 coal-fired power plant, using an animated light show to protest against the commissioning of the coal-fired station planned for this summer. The protest against Datteln 4 is also growing in Finland. The Finnish state-owned company Fortum just increased its share in the German Datteln operator Uniper to 70.5 percent. Uniper operates its power plant park with almost 90 percent fossil fuels.
