Three Gorges Dam

"The Three Gorges Dam is a Chinese hydroelectric river dam that spans the Yangtze River in Sandouping, Yichang, Hubei, China. The total electric generating capacity of the dam will reach 22,500 megawatts, at which point it will be the largest hydro-electric power station in the world by capacity. This is the biggest project that has been undertaken in China since the Great Wall and the Grand Canal. Several generators are yet to be installed; the dam is not expected to become fully operational until about 2011. As with many dams, there is a debate over costs and benefits. Although there are potential economic benefits such as flood control and hydroelectric power, there are also concerns about the relocation of over 1,500,000 people who have been or will be displaced by the rising waters; siltation that could limit the dam's useful life; loss of numerous valuable archaeological and cultural sites; and significant adverse effects upon animal life." -Wikipedia More info: http://en.wikipedia.org/wiki/Three_Gorges_Dam
