Do hydroelectrics promote deforestation in the Brazilian Amazon?
Deforestation, habitat destruction
The risks that hydroelectric dams represent are underestimated for the rainforests around the
world. It is believed that hydroelectric dams deforest beyond the limits of their installation, but the
extent of these impacts is uncertain and therefore neglected in environmental licensing. In 2024 it is
estimated that Brazil will consume 790.4 TWh in the year, 66% more than consumption in 2015,
whose consumption was 524.6TWh. To meet this demand, the preferred option has been to expand
the main form of energy production in the country: hydroelectric dams. The Legal Amazon is the
new frontier of expansion of the exploitation of this source. Here we quantify the deforestation
induced by hydroelectric plants and investigate the long-term aspects that can contribute to this
impact.
