 | | Fuel alcohols can be produced from a variety of crops, such as sugarcane, sugar beets, maize, barley, potatoes, cassava, sunflower, eucalyptus, etc. Two countries have developed significant bio-alcohol programmes: Brazil (ethanol from sugarcane) and Russia (methanol from eucalyptus). |
 | | Alcohol can also be obtained synthetically, via ethene or acetylene, from calcium carbide, coal, oil gas, and other sources. |
 | | Namely, the total fuel energy expended in producing the alcohol — including fertilizing, farming, harvesting, transportation, fermentation, distillation, and distribution, as well as the fuel used in building the farm and fuel plant equipment — should not exceed the energy contents of the product. |
