Painted black, wind turbines kill less

Between the climate emergency and the erosion of biodiversity, the solutions provided can sometimes be contradictory. So if wind turbines guarantee carbon-free energy, they are not without causing problems for birds and bats. “Wind turbines pose two types of difficulties ,” explains Kévin Barré, a researcher at Concarneau at the Center for Ecology and Conservation Sciences. Some birds are killed in flight by the blades. It is the most visible, but not necessarily the most detrimental, because there are also indirect consequences linked to the loss of habitats or the stress of animals. "

In an article published in the journal Ecology and Evolution, Norwegian researchers propose a solution to limit the direct impacts. By painting one of the three blades black, they reduced sea eagle mortality by 70%. According to the authors, the alternation of white and black in the rotation makes the wind turbines more visible to raptors. "Those are
