The consumption pattern of household energy shows that multiple fuel use is common inrnsample households and both traditional biomass fuels (fuelwood, charcoal, BLT and sawdust)rnand modem fuels (electricity and kerosene) are consumed for domestic purposes inrnAsella town.rnTraditional fuels are important energy sources in terms of both expenditure and heatrnvalue i.e., they accounts 61.39% of the total expenditure and 86.32% of the totalrnconsumption in terms of heat value while modem fuels accounts 38.61% of the totalrnexpenditure and 13.68% of the total consumption.rnThe amount of monthly expenditure on different types of household energy vanesrndepending upon the type of energy sources used which mainly determined by householdrnincome. Thus , total consumption of traditional fuels decreases with increasingrnhousehold income while the consumption of modem fuels increase with IncreasIngrnIncome.rnThe correlation between total expenditure on household energy and household size isrn+0.3156 while with household income it is +0.6010. It means it is the economic status ofrnthe households which determines the expenditure rather than household size.rnThe supply of biomass fuels on one market day and one non-market day indicates thatrnfuel wood, charcoal, BLT, tree roots and dung were supplied by different means ofrntransport: human labor (women's, men and children) and pack animals (donkeys andrnhorses).Acacia and erica arborea were the dominant tree species supplied for charcoal whilerneucalyptus, erica arborea, hagenia abyssincia and hypericum revolutun were supplied forrnfuelwood.rnThe distance-woodfuel supply relationship for the town indicates that charcoal andrnfuel wood were supplied from supply sources located at different distance. Thus,rnfuel wood and charcoal were supplied from distance located at a radius of 12.2 km andrn19.7km respectively from the center ofthe town.rnThe supply of fuelwood and charcoal was a secondary occupation to supplement meansrnof earning income for farmers, housewives, students and also for peoples without anyrnpermanent job.rnVariation in the amount of wood fuel supply and price was found between summer seasonrn(June, July and August, 1999) and winter season (Dec., 1999,Jan., and Feb., 2000). Pricernof charcoal & fuel wood was lower in summer than in winter. Low price in summerrnseason was due to food shortage and climatic condition (failure of rainfall during springrnseason of 1999). As a results rural people were forced to supply more than the need ofrnurban consumers. High price in winter season was due to shortage of supply i.e.,rnsuppliers had other means of livelihood rather than the supply of woodfuel and they werernalso involved in harvesting activities.
