The FUEL Lab at UNC-CH is involved in an impact evaluation of a for-profit renewable energy company in Rwanda that sells cooking energy in the form of fuel pellets and leases clean cookstoves to customers. Inyenyeri has a novel market-based strategy that has potential to be scaled country-wide. Our study is designed to evaluate the following impacts of adoption and use of fuel pellets and clean cookstoves: exposure of cooks and other household members to carbon monoxide, particulate matter 2.5, and polycyclic aromatic hydrocarbons; health outcomes including acute and chronic respiratory illness, chronic obstructive pulmonary disease, eye disease, and burns; and economic outcomes including consumption and expenditure patterns, time use, and school attendance. The study design is a household-level randomized controlled trial. We interview approximately 1,400 households at baseline and 24 months post intervention. For a sub-sample of 180 households we measure exposures, health indicators and outcomes, and household and intra-household economic and labor trends. A sub-study examines drivers and barriers to adoption and sustained use of the Inyenyeri household energy system. It involves qualitative and quantitative data collection, and objectively measured use of stoves using stove use monitors.
