Sugarcane Ethanol
Some forms of biomass are better ethanol producers than corn. Brazil, for example, uses sugarcane. Experts point out that an acre of sugarcane produces about 700 gallons of ethanol, while an acre of corn produces only 350 gallons.
In an effort to reduce their dependence on foreign oil, Brazil requires that all motor vehicle fuels contain a blend of at least 24 percent ethanol. Brazil's use of ethanol has greatly reduced the amount of petroleum they import.
