Why is energy not a concern for brazil?

Brazil has the perfect geography for hydroelectric production

Today, the main energy sources in Brazil are generated by hydropower, oil, mineral coal and biofuels. Some others sources are used on a smaller scale, such as natural gas and nuclear power.

Brazil is the largest energy consumer in South America. It is the most important oil and gas producer in the region and the world's largest ethanol fuel producer. The government agencies responsible for energy policy are the Ministry of Mines and Energy (MME), the National Council for Energy Policy (CNPE), the National Agency of Petroleum, Natural Gas and Biofuels (ANP) and the National Agency of Electricity (ANEEL).State-owned companies Petrobras and Eletrobras are the major players in Brazil's energy sector, as well as Latin America's.

i think the answer is true : ))
