This research analyzes the most current approaches to hydroelectricity in current Geography textbooks, endorsed by the Ministry of Education for Secondary Education. For this purpose, the following works were selected: Magnoli (2012); Araújo et al. (2015); Moreira and Sene (2012); Lozano et al. (2012). In them are identified discourses on the uses and appropriations of waters of watersheds, in particular in the Amazon. It also recognizes the pluracy of uses in basin environments, as a reality in the Amazon regional dynamics concerning the territory-territory relationship (Haesbaert, 2010) and indicates which electricity generating sources are identified as the most promising substitutes for hydroelectricity. The beginning of the investigations is destined to telematicized (Yin, 2005) and documentary research, both linked to the literature review. Interviews were conducted with teachers from the public network of Maranhão and Pará, areas historically influenced by the construction of large riverbanks. These procedures provided support for the indication of opportunities for improvement of the didactic forms examined at the close of the discussions.
