Rural Ethiopian communities predominantly rely on traditional biomass fuels for home cooking, leading to poor air quality and associated health issues. A longitudinal study employing a mixed-methods approach including baseline surveys, follow-up interviews, and air quality measurements over five years. Intervention groups receive solar cookers, control groups continue with traditional cooking methods. Solar cooker use was associated with a significant reduction in household particulate matter (PM2. 5) levels by up to 40% compared to baseline conditions, leading to an estimated 10% decrease in respiratory symptoms among intervention households over the study period. The transition from traditional biomass fuels to solar cookers demonstrated substantial health benefits and environmental improvements in rural Ethiopian communities. Policy makers should incentivize renewable energy adoption in rural areas, particularly focusing on improved access to solar technology for sustainable development goals. Treatment effect was estimated with logit (pᵢ) =₀+^ Xᵢ, and uncertainty reported using confidence-interval based inference.
