Abstract: Hydropower plants correspond 16% of the global renewable energy mix and it reaches up to 63% in Brazil [1]. Hydroelectric power industry impacts on freshwater availability can be significant if one considers the increased local evaporative losses caused by the construction of dams [2]. The water footprint (WF) is the volume of freshwater used to produce a certain product and can be used to estimate water consumption for energy supply [3]. In this work we evaluate the water footprint of major Brazilian hydropower plants for the period of 1999 to 2020.
