No 7 Hydroelectricity

China has the world's biggest hydropower producer, the Three Gorges Dam project blocking the mighty Yangtze River at Yichang in Hubei province.

According to the nation's 12th Five-Year Plan (2011-15), China will become the world’s largest generator of hydroelectricity by the end of 2015.
