Helios is an EH interview series about new research in the energy humanities and the creative processes that bring it to life. In this fifth installment, Nicholas Carby-Denning interviews University of Toronto political scientists Teresa Kramarz and Donald Kingsbury about their book Populist Moments and Extractivist States in Venezuela and Ecuador: The People's Oil? (Palgrave Macmillan, 2021). Although this conversation took place in late 2022, its exploration of energy and populist politics continues to resonate in late 2024.
