Are Wind Turbines Killing Whales?

Acoustic pollution harms humans on land and whales in the ocean.

“Between January 9 and February 4 this year, 29 sperm whales got stranded and died on English, German and Dutch beaches. Environmentalists and the news media offered multiple explanations – except the most obvious and likely one: offshore wind farms.

Indeed, that area has the world’s biggest concentration of offshore wind turbines, and there is ample evidence that their acoustic pollution can interfere with whale communication and navigation.”

“researchers at the University of St. Andrews have found that the noise made by offshore wind farms can interfere with a whale’s sonar, and can in tragic cases see them driven onto beaches where they often die,” a UK Daily Mail article observed.

It is certainly possible that permanent damage to the cetaceans’ middle and inner ears, and thus to their built-in sonar, can result from large air guns used during seismic surveys and from violent bursts of noise associated with pilings being rammed into the rock bed. Wind promoters themselves admit that their pile-driving can be heard up to 50 miles (80 kilometers) underwater, and can be harmful to whales that happen to be nearby. But unless these injuries cause external bleeding, they are very difficult to detect.”
