Current situation of biogas technology developed for rural applications has been investigated concurrently with rural energy use patterns to assess the feasibility of the technology. Fuel wood and wooden charcoal were mainly used as domestic cooking fuels with the shares of 56.8 % and 37.8 % of the total consumption respectively. Lighting was made by electricity and kerozene, whilst agricultural activities used diesel as a major fuel followed by gasolene, LPG and electricity respectively. Four types of digestor:Fixed-Dome Gas Holder, Single Walled Floating Gas Holder, Double Walled Floating Gas Holder and others were used to generate biogas mainly from cow and pig manures, and then utilized as a domestic cooking fuel. The Fixed-Dome type was found to operate most efficiently with less maintenance requirement, compared to others. By average, the users' attitude indicated positive acceptance in the technology, except for some areas where the collection of feed materials was difficult. The use of biogas other than as a domestic cooking fuel, such as for an agricultural purpose should be developed and promoted to help accelerate rural energy independence.
