Offshore wind energy deployment can significantly contribute to increasing the share of renewable energy in Europe's energy mix. However, competing uses of the sea, costs, grid integration and other barriers are important challenges to the development of offshore wind. Windspeed aimed to assist in overcoming these obstacles by developing a roadmap defining a realistic target and a development pathway up to 2030 or offshore wind energy in the Central and Southern North Sea (Belgium, Denmark, Germany, the Netherlands, Norway and the UK). The roadmap identified barriers and potential surplus conditions in the North-European electricity grid along with policy recommendations on how to tackle these.
