On November 8, 1997, engineers diverted the Yangtze River to make way for the Three Gorges Dam in Hubei Province, China. The dam is the world’s largest power plant, capable of generating 98 million megawatt-hours of electricity every year. Building the dam took 16 years and cost $30 billion.
 
The Three Gorges Dam is one of the most controversial engineering projects in history. While the Chinese government stresses a need for power generated by the dam, its construction displaced more than a million people. The dam flooded archaeological sites and caused the probable extinction of the Yangtze River dolphin.
