There’s a TakePart article that came out a while back that deals with offshore wind farms. But there’s something they fail to touch on — as do many articles on wind farms in general: the potential ongoing damage done by infrasound.
I’m certainly no expert on the subject, but for those less familiar with it… One of the problems with large wind turbines is the infrasound they generate during operation (in addition to the sound impact during the construction phase).
I’m a strong proponent of renewable energy, including wind, but all factors of impact need to be studied before any installation is implemented. What effect will the infrasound generated by multiple wind turbines have on cetaceans, and other marine life? I Googled a bit and found that one study — by the Woods Hole Oceanographic Institution — is taking place now: http://www.whoi.edu/
Land-based animals — including humans — are affected by infrasound from wind farms. The ocean carries low frequency sounds much more efficiently, and much father than the atmosphere. Some kinds of marine life use low-frequency sound to communicate, so their hearing is acute in that range. The ongoing use of active sonar technologies by the US Navy has been shown to injure and even cause the death of cetaceans. Die-offs and beachings of whales and bottlenose dolphins have been increasing.
Will we start to see a more rapid die-off rate once wind farms are installed offshore? Do we have to wait until that starts happening — after the damage is being done, and after countless millions of dollars are committed — to find alternatives? Or will we perform the due diligence needed in every instance of large-scale construction of facilities like these?
