Two-thirds of Brazilís energy comes from renewable sources, particularly hydroelectricity. Oil and natural gas are the main nonrenewable sources, followed by coal. Renewable resources are domestically produced, but Brazil also imports about 10 percent of its total energy needs, principally oil and coal.
Almost half of the hydroelectric capacity is located on major rivers in the Southeast, close to the highest concentrations of population and industry. Improved transmission technology and the construction of industries, such as metal smelting, that use large amounts of electricity have begun to tap into the considerable hydroelectric resources of the Amazon region. The biggest hydroelectric station is Itaipu, in Parana, which Brazil shares with Paraguay. Other large stations are Tucurui in the Amazon region, Paulo Afonso in Bahia, Itumbiara in Minas Gerais, and Ilha Solteira in Sao Paulo. In the South, burning coal supplies thermal power, and there are oil-fired power stations elsewhere. Brazil has taken some tentative steps in the production of nuclear power.
Wood and charcoal are still widely used in rural areas for cooking. They are also important commercial sources of energy, particularly in iron smelting and lime making. Sugarcane is also significant, both as a source of commercially distilled fuel for motor vehicles and as bagasse, the remains of crushed sugarcane stalks, which is used as fuel in sugar mills.
