In Africa, Kenya included, the dependence on natural regeneration compounded with increased use due to population pressure and wood fuel depletion is a major concern in the region. This led to the introduction of the firewood conservation stove to reduce consumption of firewood which is the man insource of domestic energy in Kenya. Although the intervention is in place, sustainable wood energy has not yet been achieved. Therefore there is need to assess the contribution of the intervention measure in enhancing sustainable wood energy use The main objective of the study was to assess the contribution of the firewood conservation stove in sustainable use of wood fuel energy in Embu north Sub County, Embu County, Kenya. The specific objectives are; to assess the level of awareness on the stove in Embu North Sub County, Evaluate how the cost of the stove influenced its impact in sustainable use of woodfuel, finally to assess the level of utilization of the stove and the effect of this to sustainable wood fuel use in the study area.
