Gradually increasing biogas and biomethane consumption to 20% by 2030 and replacing natural gas use can help India reduce its dependence on the fossil fuel and cut import bills by nearly US$29 billion, a new report by the Institute for Energy Economics and Financial Analysis (IEEFA) finds. The report adds that increasing biogas projects will be multi-pronged environmental solution as it helps manage waste, reduce greenhouse gas (GHG) emissions and increase renewable energy production.
