All of Paraguay's electricity is generated by hydropower, making it one of the cleanest in the world. Paraguay has an installed electrical production capacity of 8,110 MW, producing 63 billion kWh/year in 2016; with domestic consumption of just 15 billion kWh, the excess production is sold to Brazil, Argentina, and Uruguay, making Paraguay the world's largest exporter of electric power. This production is from two large hydroelectric power projects along its borders, including the Itaipu Dam, the world's second largest generating station.
