where most projects are based. The Brazilian Wind Energy Association and the government have set a goal of achieving 20 GW of wind energy capacity by 2020 from the current 5 GW (2014). The industry hopes the auction will help kick-start the wind-energy sector, which already accounts for 70% of the total in all of Latin America. According to Brazil's Energy Master-plan 2016-2026 (PDE2016-2026), Brazil is expected to install 18,5GW of additional wind power generation, 84% in the North-East and 14% in the South. Brazil started focusing on developing alternative sources of energy, mainly sugarcane ethanol, after the oil shocks in the 1970s. Brazil's large

Total energy matrix and Electric energy matrix

The main characteristic of the Brazilian energy matrix is that it is much more renewable than that of the world. While in 2019 the world matrix was only 14% made up of renewable energy, Brazil's was at 45%. Petroleum and oil products made up 34.3% of the matrix; sugar cane derivatives, 18%; hydraulic energy, 12.4%; natural gas, 12.2%; firewood and charcoal, 8.8%; varied renewable energies, 7%; mineral coal, 5.3%; nuclear, 1.4%, and other non-renewable energies, 0.6%.Matriz Energética e Elétrica

, the dam provides over 75% of Paraguay's electric power needs, and meets more than 20% of Brazil's total electricity demand. The river runs along the border of the two countries, and during the initial diplomatic talks for the dam construction both countries were suffering from droughts. The original goal was therefore to provide better management and utilization of water resources for the irrigation of crops. Argentina was also later incorporated in some of the governmental planning and agreements because it is directly affected, being downstream, by the regulation of the water on the river. If the dam were to completely open the water flow, areas as far south as

could potentially flood. Construction of the dam started in 1975, and the first generator was opened in 1983. It is estimated that 10,000 locals were displaced by the construction of the dam, and around 40,000 people were hired to help with the construction of the project. Many environmental concerns were overlooked when constructing the dam, due to the trade-off considering the production of such a large amount of energy without carbon emissions, and no immediate harmful byproducts, such as with nuclear energy.
