Itaipu Dam  

Itaipu Dam is the most powerful hydroelectric dam. It was built in 1984. This dam is located on the border of Brazil and Paraguay. Parana River is the main source of energy to run this dam. This river is one of the largest rivers in the world. The term ‘Itaipu’ means ‘the sounding stone’. It was named after a small island very close to where the dam is located. The deal between Brazil and Paraguay to build the dam was signed on July 22, 1966, but the construction did not start till 1971. In 1994, the Itaipu Dam was selected as one of the seven wonders of the modern world.
