Oceans of Opportunity Harnessing Europe’s largest domestic energy resource A report by the European Wind Energy Association Oceans of opportunity Europe’s offshore wind potential is enormous and able to power Europe seven times over. Huge developer interest Over 100 GW of offshore wind projects are already in various stages of planning. If realised, these projects would produce 10% of the EU’s electricity whilst avoiding 200 million tonnes of CO2 emissions each year. Repeating the onshore success EWEA has a target of 40 GW of offshore wind in the EU by 2020, implying an average annual market growth of 28% over the coming 12 years. The EU market for onshore wind grew by an average 32% per year in the 12-year period from 1992-2004 – what the wind energy industry Oceans of Opportunity has achieved on land can be repeated at sea. Building the offshore grid EWEA’s proposed offshore grid builds on the 11 offshore grids currently operating and 21 offshore grids currently being considered by the grid operators in the Baltic and North Seas to give Europe a truly pan-European electricity super highway. Realising the potential Strong political support and action from Europe’s policy-makers will allow a new, multi-billion euro industry to be built.

Offshore wind power provides the answer to Europe’s However, the wind energy sector has a proven track energy and climate dilemma – exploiting an abundant record onshore with which to boost its confidence, energy resource which does not emit greenhouse and will be significantly longer lived than the oil and gases, reduces dependence on increasingly costly gas sector. fuel imports, creates thousands of jobs and provides large quantities of indigenous affordable electricity.
