The report shows that by 2020 most EU countries will have at least tripled their wind power capacity reaching a total installed wind farm capacity of 230 gigawatt (GW) by 2020 – providing 15.7% of EU electricity depending on demand. 190 GW would be onshore and 40GW offshore. By the end of 2010, 84 GW of wind energy capacity was operating in Europe, meeting 5.3% of EU power demand.
By 2030 EWEA expects 400 GW of wind to be operating in the EU providing 28.5% of EU electricity depending on demand. 250 GW would be onshore and 150 GW offshore. The report also shows that wind power could provide 50% of the EU electricity supply by 2050.
