Household energy consumption regularly constitutes 90% of total energy use in most developing countries through the world. Woody biomass accounts 87% of the total annual biomass energy use globally. It has been estimated numerically that about 2.5 billion people in the developing countries solely depends on a biomass energy sources to meet their household energy demand. Most of rural Africa countries use traditional biomass energy sources for their household cooking and lighting. In 2017 statistics of international energy agency (IEA) data indicates that 45.3% of Africa energy consumption is from biomass and agricultural residues. The analyses of improved energy saving appliances were conducted and the constraints and opportunity related to household energy sources and use is also performed in the Wolaita zone. In sample survey, sample size determination was an important step in the process of statistical analysis and according to data obtained from Housing Development Section of the Wolaita zone, 110 households were used in the analysis of household energy consumption; which is sufficiently enough according to the sample size calculated above. This survey study shown that the traditional biomass energy sources were the principal energy source having the highest percentage share (96 %) of sampled households for Injera baking, 96 percent for Wot, 91 percent for tea and 93 percent for coffee. In fact, the contribution of modern energy source is minimal except slightly in the preparation of tea that is by using kerosene stove habitually called as Butagas makes sizeable use as shown in fig.2 above. Further analysis indicated that wood is used as the principal biomass energy source for Injera baking share 93 percent of households, followed by zero percent dry cow dung. A zero percent of the sample households also use electrical energy for Injera baking. It is further indicated that charcoal is also the principal energy source for wot cooking; tea preparation and coffee making and is share 72, 60 and 57 percent of households energy supply respectively. While the pattern for tea reveals that slight difference exist between the traditional biomass and modern energy sources especially with that of kerosene.
