Ethanol is an organic chemical substance and a renewable fuel made from various plant materials collectively referred to as biomass. While second-generation (2G) ethanol plants use extra biomass and agricultural waste, first-generation (1G) ethanol is produced from raw materials like cereals, sugarcane juice, and molasses. When ethanol is added to gasoline, carbon dioxide emissions are decreased. The increase in auto fuel volume and consequent decrease in dependence on foreign oil helps India get closer to its goal of energy security.
