The Three Gorges Dam generates more electricity than any other hydroelectric dam in the world. About 50 million tons (45 million meteric tons) of coal would need to be burned to produce the same amount of electricity annually. The dam also helps control flooding.
However, the Three Gorges Dam has created a new reservoir that has flooded many towns and cities along the Yangtze River. As a result, about 1.3 million people have been displaced. The reservoir created by the damming of the river extends 370 miles (600 km) upriver, to Chongqing.
Historical sites, such as the Shibaozhai Temple and the many pagodas along the Yangtze River, attract large numbers of Chinese visitors and foreign tourists each year. The Shibaozhai Temple was built on the northern bank of the river in the 1700s. Tourists visit Shanghai to see places such as the Bund, City God Temple, and the Oriental Pearl Tower.
