Detailed explanation-1: -Ethanol is a domestically produced alternative fuel most commonly made from corn. It is also made from cellulosic feedstocks, such as crop residues and wood-though this is not as common. U.S. ethanol plants are concentrated in the Midwest because of the proximity to corn production.

Detailed explanation-2: -Biofuels are used mainly for transportation. There are two types of biofuels: bioethanol and biodiesel. Bioethanol, the principal fuel used as substitute for petrol for road transport vehicles, is mainly produced by the sugar fermentation process of cellulose (starch), which is mostly derived from maize and sugar cane.

Detailed explanation-3: -The two most common types of biofuels in use today are ethanol and biodiesel, both of which represent the first generation of biofuel technology. The Bioenergy Technologies Office (BETO) is collaborating with industry to develop next-generation biofuels made from wastes, cellulosic biomass, and algae-based resources.

Detailed explanation-4: -Corn grain makes a good biofuel feedstock due to its starch content and relative easy conversion to ethanol. Infrastructure to plant, harvest and store corn in mass quantities benefits the corn ethanol industry.
