摘要

The study shows the current energy consumption pattern and Green House Gases emission. The study is focused to analyze the status of Biogas as a Renewable Energy Technology (RET) and its role in reducing the consumption of traditional energy resources and GHGs emission. The total energy consumption among the sampled households was found to be 7225.72 GJ per year with 14.06 GJ per capita per year. Fuelwood was found to be the dominant energy resource which comprises 93.73% of the total energy and rest 6.27% of energy was supplied by other sources like electricity, kerosene, solar and LPG. The per capita biomass fuel consumption was 13.18 GJ per year, whereas non-biomass fuel consumption was 0.868 GJ. The per capita Greenhouse Gases (GHGs) emission was found to be of 1209.11 kg CO2e per year of the study area. The annual GHGs reduction was found 7.62 tCO2e per biogas plant i.e. GHGs emission of 205.62 tCO2e per year was reduced from the 27 biogas plants available in the sampled households and the study showed that the possibility of another 57 biogas plants of size 6 m~3 which can reduce another 433.20 tCO2e per year of GHGs emission. The study showed that the use of biogas saved 46.67% of fuelwood and if all the 84 potential biogas plants were constructed from the dung produced annually, the amount of fuelwood saved would be 217.32 tons per year per household. The simple payback period of the biogas plant was found to be 3.06 years excluding the subsidy given by the Government of Nepal. Therefore, the RET used in the study area had either reduced or substituted fuelwood as an energy source. The reduction on GHGs emission by the installation of biogas and high potentiality of biogas on the basis of livestock clearly indicates biogas as a suitable RET in reducing GHGs emission with efficient energy use.
