Edited by Michael ArndtWith many states clamouring for more green energy, windmills are among the most cost-effective options.

A National Academy of Sciences study estimates the toll of bird deaths from U.S. wind farms is in the tens of thousands per year, a tiny fraction of the hundreds of millions of birds killed by house cats and man-made menaces such as pesticides, cars, and power lines. The Audubon Society now says ordinary power plants pose a bigger threat to bird life than do windmills.
