The Three Gorges Dam is the world's largest power producing facility, and the world's largest hydroelectric dam. There were many reasons for building the dam and this article will investigate some of these. The Three gorges dam was built across the Yangtze River to control the amount of water allowed through.

The Itaipu dam and the hydroelectric plant are on the Paraná River. The construction of the dam began in February 1971 and cost $19.6bn. The first unit began generating power in May 1984 and the second generating unit started operating the same year. Itaipu has 20 generating units, each with a capacity of 700MW.

The country's installed power generating capacity of 334.4 gigawatt (GW, or 1,000 megawatts) as of January 2018 is the world's fifth-largest. Over the last five years, India put up 99.21 GW of additional capacity. Of this, 91.73 GW came from thermal sources, 5.48 GW from hydro, and 2 GW from nuclear sources.
