What is Bioethanol?

From Christine & Scott Gable, for About.com

Definition: Bioethanol is ethanol (alcohol) that is derived exclusively from the fermentation of plant starches. Though ethanol can be extracted as a by-product from a chemical reaction with ethylene and other petroleum products, these sources are not considered renewable.

Chemically, bioethanol is identical to ethanol and can be represented by either the formula C2H6O or C2H5OH.
Also Known As: ethanol
Examples: Bioethanol can be fermented from sugar cane, switchgrass, grains and agricultural waste.
