Scientists studying impact of painting wind turbine blade black to reduce bird collisions
The Oregon State researchers, working with federal, industry and nonprofit partners, and funded in part by the Oregon Legislature(Link is external), are building on recent research in Norway that found a nearly 72% decline in bird collisions with turbine blades when one blade was painted black.
[There are typically three blades on a wind turbine.]
From Deutsche Welle:
According to an overview of median estimates of annual bird deaths by the US Fish & Wildlife Service, the main culprits in the US are cats (2.4 billion), collisions with glass buildings (about 600 million) and collisions with vehicles (about 215 million). Collisions with land-based wind turbines are toward the bottom of the list with about 234,000 deaths a year, well after collisions with electrical lines, communication towers or poison.
Wind power makes up about 10% of total electricity in the U.S., 28% in Germany, and 58% in Denmark.
