Abstract
The rural population of Ethiopia entirely depends on biomass for everyday energy needs except for light. The traditional system, particularly during cooking, incurs among others huge energy loss that could have been used otherwise. The system has been recognized as having significant effect on natural resource degradation, harmful health hazards and negative economic consequences. As a result, the government has been encouraging the use of energy saving technologies. Mirt and Gonze stoves are the two most dominantly promoted technologies. Promotion and efficiency evaluations were conducted. The result of the evaluation confirmed that households that use Mirt and Gonze stoves can save more than 33% and 20% of wood biomass that could have been used if traditional open stove was used, respectively. The time efficiency, length of time the stoves gave energy to bake additional Injera for Mirt and Gonze was increased by 63% and 50%, respectively. Thus, Mirt and stoves are efficient than the traditional open stoves. Due to durability, farmers preferred Mirt stove over Gonze. Utilization of Mirt stove can save 15% of wood biomass over Gonze. Promotion of Mirt stove in rural Ethiopia is vital to enhance biomass energy efficiency.
