The major purpose of this study was to examine the advantages and implications of biogas technology in the agriculture sector. Biogas is one of many biomass energy sources, which include anything that was once alive and that can generate energy (except for fossil fuels, which are not renewable). To talk of biogas is to talk of agriculture, since biogas generation starts with agricultural waste produce, such as cow dung, husk, straw etc. and ends with agricultural produce, use of slurry on crops. Slurry is one of the most environmentally sound organic fertilizers in use today. The information collected in this study by reviewing literatures. Renewable energy sources have a large potential to contribute to the sustainable development of specific territories by providing them with a wide variety of socioeconomic benefits, including personal/household impacts, health impacts, social, economic and environmental impacts. Biogas as an adaptive and cost-effective energy system, integrate livestock into the farming system.
