Most of it is hydropower. But most good hydropower sites are already tapped, so we shouldn't expect this source growth to keep pace in the future. So, to keep these numbers good, it's necessary to crank up the deployment of solar panels and wind turbines a lot.
Also solve the deforestation problem for good, otherwise Brazil will shoot its own feet by causing deforestation-induced droughts to decrease available hydropower.
