Abstract
Biomass energy source has been the major source of cooking energy for major segment of Ethiopian population for thousands of years. To investigate household energy consumption pattern of biomass energy sources and the biomass energy quality and safety of technology (wood-stoves) in respect to climatecal, socio-economical and environmental benefits in the wolaita zone. A community based cross-sectional study was conducted employing both quantitative and qualitative approaches on systematically selected 138 households for quantitative and purposively selected 110 people for qualitative parts. Descriptive statistical method and qualitative analysis were used as methodological tools. Moreover, one way analysis of variance (ANOVA) was fitted to assess possible associations and its strength was measured using odds ratio at 95percentCI.The study indicated that 99.93perrcent of households still use biomass energy for cooking. More than 15 percent of households collect tree biomass from their own homestead forests while 79 percent of households acquire their biomass energy through purchase from neighbors’ market and remaining 6 percent of household both collect and purchase. Testing reveals that quantity of firewood consumption by high income households was significantly higher than that of medium income and low income category households. Those who were less knowledgeable about negative health and environmental effects of traditional utilization of biomass energy sources were 5.11 and 3.58 times more likely to utilize them compared with those who were knowledgeable. The most outstanding finding of this study was that households use traditional biomass energy for cooking mainly due to lack of the knowledge and their beliefs about food prepared using biomass energy. Although 13% households were using improved cooking stoves (ICS), mass motivation and subsidized ICS can increase their uses. Therefore, mechanisms should be planned to promote modern energy and to teach the public about health, and environmental as well as climate effects of traditional way of utilization of biomass based renewable energy source. Along with reforestation programs government may take initiative for climate compatible development from ICS programs on household energy markets as part of the Clean Development Mechanism (CDM).
