Birds have been a problem for wind power. Wind turbines, whatever their other merits, have the tendency to kill birds, and possibly bats. This has been a longstanding problem, particularly because those areas best for wind power are often important for birds, particularly those species that tend to ride on wind currents.
The bird problem has meant that environmental organizations have been inconsistent advocates of wind power, endorsing the such carbon-free power in the abstract, but often opposing particular wind power development proposals. I wrote about this problem over twenty years ago in The Weekly Standard, and it has not gone away.
New research suggests that one solution to the bird problem is rather simple: Painting one blade black dramatically reduces bird kills by wind turbines–70 percent in one location under study. This is an important development because the effect appears quite large, and it’s a relatively inexpensive fix. Assuming this research pans out, there is a cheap way to address the biggest environmental drawback of wind power, and that’s a big deal.
