The World's First Floating Wind Farm Is Already Changing Green Energy
In September 2012, 19 pilot whales, a minke whale and a large sei whale beached on the coast of Scotland opposite an area where air guns were being used by ships surveying the ocean floor, as a prelude to installing offshore wind farms. “A second pod of 24 pilot whales was spotted in shallow water by Cellardyke around the same time, but [it] returned to sea without beaching,” the article noted.
Offshore turbines were also associated with “many” stillborn baby seals washing up onshore near the UK’s Scroby Sands wind farm in June 2005. “It’s hard not to conclude the wind farm is responsible,” the author concluded.
Many more similar deaths may well have been caused by wind farms at sea. The scientific and environmental literature abounds in warnings about risks to marine mammals from man-made noise.
Modern 8-megawatt offshore turbines are 656 feet (200 meters) above the waves; their rotating blades sweep across a 538-foot (164-meter) diameter. Those enormous blades create powerful pulsating infrasound and exact a toll on many species of marine birds, and even on bats that are attracted to the turbines as far as 9 miles (14 km) offshore.
In a February 2005 letter, the Massachusetts Audubon Society estimated that the proposed Cape Cod wind project alone would kill up to 6,600 marine birds each year, including the roseate tern, which is on the endangered list.
Do we really want to add marine mammals to the slaughter of birds and bats, by expanding this intermittent, harmful, enormously expensive and heavily subsidized energy source in marine habitats?
In addition, having forests of these enormous turbines off our coasts will greatly increase the risk of collisions for surface vessels, especially in storms or dense fog, as well as for submarines. It will also impair radar and sonar detection of hostile ships and low-flying aircraft, including potential terrorists, and make coastal waters more dangerous for Coast Guard helicopters and other rescue operations.
The offshore wind industry makes no sense from an economic, environmental, defense or shipping perspective. To exempt these enormous installations from endangered species and other laws that are applied with a heavy hand to all other industries – and even to the U.S. and Royal Navy – is irresponsible, and even criminal.
