The number of countries using wind energy for electricity generation increased in the first half of 2011 to 86, according to international non-profit association WWEA. The total capacity of wind turbine installations across the world is now over 200 GW, with annual generation of over 430 Twh. This is equal to 2.5% of global electricity consumption.
