Brazil’s electricity matrix is predominantly renewable, with hydro installed capacity totaling 68% of the
total supply, while biomass, wind, SHPPs and solar account for 16%. In the next years, it is expected that
other sources will grow, mainly wind and solar, reaching 12% and 3% respectively of total installed
