Brazil has begun the process of identifying new sites for new nuclear power plants. The first step was the recent signing of a cooperation agreement between the federal Ministry of Mines and Energy and the Centre for Electric Energy Research (acronymed to Cepel, in Portuguese). Brazil has one of the lowest carbon electricity generation systems in the world. This is the result of its very heavy dependence on hydroelectricity, which stood at 80% for many years. But by 2018 this figure had declined to 65%, entirely as a result of changes in rainfall patterns. Brazil thus needs to diversify its generation capacity while retaining its low level of carbon emissions.
