The project aims to construct energy efficient cook stoves for rural communities in the former Siaya district in Nyanza Province, Kenya. The efficient cook stove is a biomass rocket stove designed for burning wood and consisting of two cooking units that can be separately fired. The stove is fixed and installed in households and reduces firewood consumption by approximately 40-50%. The efficient cook stoves are constructed using locally available materials, such as mud, bricks and sawdust. Local artisans are identified in the villages and trained in stove construction and household mobilization. An innovative village based group savings and loan scheme will be integrated to enhance affordability and access to stoves.
