By Ana Karine Pereira* Electricity currently plays a very important role in Brazil’s energy matrix, equivalent, in 2010, to 17.2% of the country’s total energy supply (PDE 2019). The principal sources of electricity are hydroelectric dams, which were responsible, in 2005, for 83.4% of all electricity generated (Souza, 2008). The large role of electricity, particularly hydroelectricity, in the country’s energy matrix is explained by government planning, which in the last few decades, has emphasized this energy source. Despite the fact that the government has expanded the number of hydroelectric dams in the past few decades, Brazil still uses only 30% of its hydroelectric potential, which means that this source of energy will continue to be a priority in plans to expand national energy supplies. The problem is that most of this unused potential is located in the Amazon, which has turned the region into the country’s new energy frontier.
