Controversial Three Gorges dam has problems, admits China

(May 19, 2011) The world’s largest hydroelectric project was designed to tame the flood-prone Yangtze River and to generate clean energy. But the water is becoming polluted, and regular landslides are making life near the dam dangerous. Three Gorges dam is “a classic case in which government officials exaggerated the benefits and underestimated the risks,” says Patricia Adams of Probe International.

Anatomy of a dam failure

(April 27, 2011) In the world of engineering, standards are the foundation on which everything else rests. An investigation following a catastrophic explosion at Russia’s largest hydropower station in the summer of 2009 revealed poor management and technical flaws to be at the root of the dam’s failure. A repaired turbine almost at the end of its life span, taken offline again because it still didn’t work, was forced back into service in an emergency: a move that would cost 75 people their lives. This Popular Mechanics investigation asks whether the United States, a country with hundreds of hydro plants in operation, might also be at risk of a Russian-style dam disaster. U.S. experts say not likely: the two countries are separated philosophically when it comes to safety and human life.
