The construction of wind turbines as a cornerstone for the production of climate-friendly electricity is rapidly increasing all over the world – and everywhere this results in major challenges for bats, which die directly at the turbines or lose valuable habitats in their vicinity. A research team from Australia, Brazil, France, Germany, Kenya, Puerto Rico, Taiwan, the United Kingdom and the USA now analysed possible solutions to this green-green conflict on a global scale and identified the steps required to improve the balance between climate protection and biodiversity conservation.
