When plans for Neart na Gaoithe started being developed in 2008, Siemens AG’s 3.6 megawatt turbine was the most popular among developers. Now manufacturers are working on machines that could be four times bigger, helping companies like Dong Energy A/S build projects cheaply enough to make money at market prices. The collapse in oil prices has also helped lower offshore wind costs, by making the sea vessels needed to install projects cheaper to hire.
I’ve haven’t seen a satisfactory solution for the problem of wind turbines impact on migratory bird populations regardless of the fact offshore turbines help create artificial reefs for sea life. However, the economies of scale that can be gained from going offshore has altered the wind turbine sector beyond recognition.
