Beyond their agreement about the need for the benign energy production of wind turbines, however, disagreements arise and we could be headed for gridlock. Perhaps the best example of this is to be seen in the headline over an otherwise reasonable newspaper statement by Elmer Marien, president of the Buffalo Audubon Society. It reads: "Keep Wind Turbines out of Migration Routes". Since birds migrate across broad fronts that cover all of North America, that order could effectively end wind power.



Indeed wind turbines can kill birds.



Today's windmills are giants. You can see ten in action in the Wyoming County Town of Wethersfield. Each 213-foot turbine tower there supports three 77-foot blades. Thus they reach a height of about 290 feet, still, however, well below the usual flight path of both day and night-flying bird migrants. Their blades turn at 28.5 revolutions per minute but, while they appear to be moving slowly, that is an illusion. Their tips swing at over 150 miles per hour and no bird could survive being hit by a blade at that speed
