Over the past three years, ABB’s wind power business has grown on average over 50 percent a year, but historically there have been difficulties associated with wind farms, such as the amount of space they occupy, the importance of their siting (without obstructions such as trees or hills), their noise and the threat to birds and bats. An obvious but only recent solution is to site the wind farm offshore, such as the Borkum-2 wind park, which is situated in the North Sea over 100 kilometers off the coast of Germany.
