Twelve hours of power outages daily from the national grid in the current season and up to sixteen hours in the lean
period is the state of commercial energy in Nepal. Women in rural areas spend a considerable amount of their time in the
collection of firewood, where it is mostly used for cooking. With ever increasing population in the developing world and
depleting fossil fuel reserve, this dependence shows a rising trend. In this paper various benefits related to the use of renewable
energy are minutely analyzed. Time spent in the collection of fire wood before and after the construction of plant, distance
travelled in the collection of firewood before and after, time saved and firewood saved are some of the variables which try to
assess the benefits of a biogas plant. These results are based on the data of a socio-economic survey of 400 households, where
information about a typical middleclass Nepalese family using biogas and inhabiting in rural areas, its economic, social
background and the resulting change are collected. This survey was conducted during September – December 2010 in three
different rural settings of Nepal. The questionnaire for this survey was carefully pretested and refined. All the possible sources
of error were identified and carefully eliminated
