Ethanol is being increasingly used in our transport fuels, especially gasoline as an additive. It is most commonly produced from biomass such as sugarcane, corn, switchgrass, etc. An increase in oil price in the international market has made ethanol addition an attractive option. This has had profound impact on agriculture of these crops. Due to their demand, the cultivated area under these crops has been increasing. And because of their commercial application, more and more crops are being diverted to biofuel production from food production. This has raised ethical and social concerns: should the food crops be used for commercial applications instead of food applications? A positive aspect of use of ethanol in fuels is the decrease in consumption of fossil fuels, even though ethical and social concerns are there.

Hope this helps.
