Press release of the European Wind Energy Association (EWEA). 100 GW of wind power can generate electricity over a year to meet the total consumption of 57 million households, equivalent to the power production of 39 nuclear power plants. It took the European wind energy sector some twenty years to get the first 10 GW grid connected. It only needed 13 years to add an additional 90 GW. Half of the total European wind power capacity has been installed over the past six years.
