Where are hydropower plants located in the world?
China, Brazil, Canada, the United States, and Russia are the five largest producers of hydropower. The world’s largest hydroelectric plant in terms of installed capacity is Three Gorges (Sanxia) on China’s Yangtze River, which is 1.4 miles (2.3 kilometers) wide and 607 feet (185 meters) high.
Where is the best location for hydroelectric power?
The best location for a hydroelectric station should be along the path of a river. It should be at least at the river canyon or at the place where the river narrows. This enables the collection of the water or the diversion of the river.

Why isn’t hydropower used more?
Hydropower fell out of favor in the ’90s because of the harm it can cause to communities and ecosystems. However, a recent push from the World Bank for more hydro projects worldwide, especially in developing countries, could lead to a resurgence of hydropower plants, the Washington Post reports.

Why hydroelectric power is bad?
Hydropower can impact water quality and flow. Hydropower plants can cause low dissolved oxygen levels in the water, a problem that is harmful to riparian (riverbank) habitats and is addressed using various aeration techniques, which oxygenate the water.
