Ethanol Pump, courtesy of Warren Gretz, DOE/NRELEthanol, a renewable alternative to petroleum-based transportation fuels, is a type of alcohol produced by fermenting and distilling simple sugars from biological sources. While ethanol can be made from sugarcane, sugar beets, wheat, barley, potatoes, and many other crops, over 90 percent of U.S.-produced ethanol is currently made from corn.

Newer manufacturing processes allow ethanol to be made from cellulosic feedstocks, such as agricultural waste, forest residue and municipal solid waste. While not yet widely commercialized, these processes are currently the subject of intensive scientific research and speculation.

Many farmers are already selling corn for ethanol production, while others are part-owners in ethanol plants. As cellulose-based ethanol becomes a reality, new markets will emerge for crop residues as well as energy crops like switchgrass. Many challenges will also emerge for truly sustainable ethanol production, including protecting soil and water quality and preserving opportunities for local ownership.
