Abstract: The purpose of this paper is to investigate the association between hydroelectric energy consumption and CO2 emissions in the USA from 1980:1 to 2019:8 by using the wavelet transform model. This research revealed that (a) in the short runs (at higher frequencies), hydro energy uses intensified CO2 emissions for the periods 1990:01–1992:12, 1994:01–1994:12, and 2002:07–2007:11, and (b) during the longer periods (at lower frequencies), however, hydro energy consumption diminished CO2 emissions for the periods 1983:01–2001:12 and 2011:01–2017:03.
