Huge controversy surrounded the construction between 1994 and 2006 of what was the worlds largest hydroelectric dam, the Three Gorges Dam. Spanning Chinas 1.4-mile wide Yangtze River in the Hubei province with twenty-six state-of- the-art turbines, the dam has been heralded by the Chinese state as a symbol of Chinas modernisation and engineering prowess. It supports Chinas economic development by supplying over ten percent of its electricity. However, over 1.3 million people were deliberately displaced as part of the Gorges flooding project that created the dams 660km-long reservoir. Hundreds of archaeological sites, initially above and below ground level, were lost under the reservoirs water. Questions remain as to whether the dam  as a source of renewable energy  benefits the surrounding environment, or depletes it by causing, for example, landslides and the death of fish species in the Yangtze.Supporters argue that the Dams deepening of the river has made the Yangtze easier for large ships to navigate and has reduced the risk of flooding downstream. As the only other viable Chinese energy source continues to be non-renewable coal power, the hydroelectric power generated by the dam may be the lesser of two evils.
