The impact of global warming has drastically affected the ecosystem and also the life on earth. The main causes of global warming are the pollutant gases which are released into the atmosphere by different sources. The major one being the automobile industries followed by different wastes that are generated on a daily basis. So the gases released during the combustion or burning of wastes are responsible for global warming. The present paper gives a complete idea of the emerging technology for the production of clean and green energy in the form of biogas. Biogas is a sustainable energy constituting methane to a major amount along with some other gases. Among greenhouse gases, methane stands in the second place after Carbon dioxide and together constitutes 92% of the total global warming. The use of conventional fuels has caused a drastic change in the environment which can be reduced using Non- conventional fuels. Biogas can fulfil the need to a great extent. Biogas has the capability of replacing the present conventional energy sources as it is clean and eco-friendly. A famous saying, “With the use of biogas we can see the light at the end of the tunnel”. This paper also reviews different stages of anaerobic digestion, properties of biogas, impact on the environment and the production rate through various techniques and utilizing different feedstocks. It also depicts the economic impact of biogas on society and ecosystem.
