[From introduction] The report estimates that between 20 GW and 40 GW of offshore wind energy capacity will be operating in the European Union by 2020. A fully developed European offshore wind resource could deliver a capacity of several hundred GW to supply our future energy demands. Developing less than 5% of the North Sea surface area would enable offshore wind to supply roughly one-quarter of the EU’s current electricity needs. [WSJ Environmental Capital]
