European researchers test black wind turbine blades to reduce bird deaths

Researchers in Europe are investigating whether painting wind turbine blades black could reduce bird collisions, a leading cause of avian mortality from renewable energy infrastructure. According to DW Planet A, while the black coloring may improve blade visibility to birds, the science remains complex — some studies suggest birds avoid darker objects, while others show no significant effect depending on species and lighting conditions. Wind energy expansion across Europe has intensified pressure to solve bird mortality without compromising renewable energy targets.
