Do households use improved cook stoves? What are the benefits? An Ethiopian case study
About 40% of the human population, or about 2.8 billion people, find commercial fuels like electricity and gas inaccessible, too expensive or too irregularly supplied to use for cooking and heating (Smith et al., 2013; IEA, 2012). Instead, they rely on solid fuels like coal, fuelwood, dung and charcoal that are combusted inside their homes.
