"Offshore wind energy critics often cite the risk of collision with birds as an argument against the use of wind power. But a new study conducted by European energy company Vattenfall shows that offshore wind turbines at one UK wind farm are much less dangerous to birds than previously thought, a step towards debunking common claims that turbines are a major contributor to bird mortality.
Vattenfall’s study looked at seabird behavior over a period of two years at the Aberdeen Offshore Wind Farm located in the North Sea on the east coast of Scotland. The company describes the study as most comprehensive and technologically advanced in the field to date, using radar and cameras to monitor how birds behaved.
What did the study find? Not a single collision between a bird and a blade was recorded. In fact, seabirds actually deliberately avoid wind turbine rotor blades offshore. "
