My viewpoint was, and still is, that the huge towers (260 feet high), gigantic blades (add another 150 feet), blinking strobe lights, permanent removal of wind-hindering vegetation, and highly visible road and transmission infrastructures are totally inappropriate for wild, undeveloped, scenic and highly visible settings. And I said I thought that opponents should focus on those issues, as well as the small return in electricity for the massive public price paid, aesthetically and otherwise, and should perhaps stay away from the issue of bird mortality caused by the rapidly spinning blades. The jury is still out on that, I said, and conventional wisdom is that vastly more birds are killed by high-rise windows and free-running cats......Well, so much for conventional wisdom.

Editor's Note This opinion piece was written in response to a letter received from Lisa Linowes that is available via the link below.

In your column, you state bird mortality is a subject that wind energy opponents should stand down from. However, there is good reason for us to continue to shed light on this problem. To our knowledge, no commercial scale wind facility in the United States has been subject to pre-construction avian risk assessments that included remote sensing (radar or acoustical).
