In 2022, China was the leading country in terms of hydroelectricity generation worldwide with approximately 1,303 terawatt hours generated from hydro sources. In comparison, Russia's hydropower facilities generated some 197.41 terawatt hours of energy that year.
Much of Brazil’s hydropower potential arises from the northern Amazon River basin. However, the majority of the country’s population lives along the eastern coast as well as the southern parts of the River. The distance and separation of the majority of the country’s hydroelectric resources and its demand has caused some reliability issues. For example, the 2014 drought led to many blackouts in various regions across the nation. A Belo Monte dam along the Xingu River was completed in 2019 and will be the second-largest hydroelectric dam in Brazil. Currently, the Itaipu Dam, located between Brazil and Paraguay along the Paraná River, is the second-largest dam in the world and has a generating capacity of 14,000 megawatts. However, the construction of large new hydroelectric power plants can create environmental impacts that alter important ecosystems, such as altering the primary flow of water systems.
