The Itapu Dam is the world's largest hydroelectric dam. There are 18 turbines and each turbine can generate enough power for a city of 300,000 people. All of Paraguay's and all of South Brazil's power comes from the dam. It was constructed in 1979 and has been called one of the Seven Modern Engineering Wonders of the World.
It created a huge lake behind the wall of the dam that at 1350 sq. km. is so wide you cannot see across it. It also wiped out the Sete Quedas waterfalls that were even more impressive than the Foz Do Iguacu, they were the world's largest waterfalls and it destroyed countless species of wildlife.
