In 2016, Rwanda began extracting methane gas from Lake Kivu, an innovative project designed to reduce the risk of a deadly spontaneous gas release while providing clean and renewable power to an energy-strapped region. Based on qualitative research in Rwanda from 2016 to 2019, Doughty, Uwizeye, and Uwimana use the Kivu methane extraction project to ask, How do we balance urgent electrification needs with responsible energy policies that respond to environmental risks, particularly in post-conflict contexts? Analyzing the Kivu methane projects as “green extractive humanitarianism” provides cautions within the promises of sustainability and “green capitalism.”
