A recent report published by the Worldwatch Institute indicates hydro-power consumption increased more than 5% between 2009 and 2010. The study found hydroelectricity accounted for a 3,427 TWh - or 16.1% - of global electrical consumption by the end of 2010. China led the world in hydropower production, producing 721 TWh in 2010 and having an installed capacity of 213 GW. In all, hydroelectricity accounts for about 17% of China's domestic electricity usage, and the country is planning to add 140 GW of hydropower by 2015. China's hydropower boom is one reason the Asia-Pacific region generated roughly 32% of the world's hydropower in 2010.
