Black Paint on Wind Turbine Blades May Prevent Flying Wildlife Deaths


Wind Turbines Versus Flying Wildlife

Health Editor’s Note: Wind turbines are a source of renewable energy and many countries have come to rely on this non-fossil fuel burning form of energy. A big draw back to wind turbines is that collisions with wind turbines yearly cause thousands of deaths to flying wildlife. Powerlines also cause deaths to birds. Placing these turbines far from migratory paths would go a long way towards avoiding harming wildlife. 

Painting at least one of the blades black seems to allow the birds to see the spinning turbines and help them to avoid hitting the blades. The black blade solution will not work at night and some birds do not ‘see’ the black blades or interpret them as things of avoidance. It would be great if there could be a solid solution to having both wind turbines and not harming flying wildlife in the process…..Carol

  1. Some effort might also be made to drill or notch the blades so they put out ultrasonic sound waves. This is an old trick, and you can still buy a device that affixes to the bumper of your truck to avoid hitting deer.

  2. The jet engine manufacturers have applied the black & white paints on the fan spinner to make the fan blades visible to ramp workers perhaps birds alike. This method that goes as far back as 1930’s made the spinning propellers of incoming aircraft more visible thus to avoid. Strips of black & white on a turning propeller or its spinner stand out at least during the day time better than black paint only.
