Renewable energy wind turbines as electricity sources possess extreme environmental problems not found in its renewable energy rival–solar photovoltaic. These problems are due to rotation during operation of 130-foot or more long, thirteen-ton turbine blades with tip speeds of 200 miles per hour.
An unavoidable problem of wind turbines is killing flying creatures. The Committee For A Constructive Tomorrow (CFACT) has produced a video “Eagle lawsuit ruffles wind industry feathers” that is shown at the following url:

The video records an eagle being killed by a wind turbine. It appears the eagle went back for a second look at the turbine and a blade struck the fatal blow. Possibly the eagle thought the turbine was a bigger bird.
A companion article by CFACT is “Wind turbines kill up to 39 million birds a year” by wildlife expert Jim Wiegand. This article is found at the following url:

Details of studies on bird fatalities caused by wind turbines are cited in this article.
It has been long known wind turbines are devastating to bat populations. A U. S. Geological Survey Report “Bat Fatalities at Wind Turbines: Investigating the Causes and Consequences”< www.fort.usgs.gov/BatsWindmills/ > mentions thousands of bats are killed annually at wind turbine sites around the world. Besides being minced by turbine blade rotations, bats are subject to deaths by other means as explained by the August 26, 2008 Scientific American article “On a Wing and Low Air: The Surprising Way Wind Turbines Kill Bats”.
The article is found at the following url: < www.scientificamerican.com/article.cfm?id=wind-turbines-kill-bats >
Bats are killed by pressure pulses causing burst blood vessels in their lungs. Due to these deaths being caused by remote features of wind turbine operations and bats very small body weights, bat carcasses may be located large distances from offending wind turbines and never found. As nocturnal creatures, bats are particularly vulnerable to wind turbines because their operations are frequently late at night when demand for electricity is at its lowest. Continue reading, here….
