Researchers found that painting a single blade black on a white wind turbine reduces bird deaths by around 70%. The step makes blades more visible as they spin, even though they sometimes reach speeds of more than 150 miles an hour.
βBecause of this high speed the rotor blades become blurred, both for humans as for birds. This effect is called motion smear. The rationale behind painting one of three rotor blades black is to reduce this motion smear effect, making the rotor blades more visible.βΒ
