Thanks Cowpie. I stand corrected. What I should have said was: From a 42 gallon barrel of crude oil everything that is made from that same barrel of crude oil totals 44.2 gallons. http://www.txoga.org/ Regarding the corn crop - I will not doubt your numbers. I will however point out that for every acre that is used for the production of corn, that is one acre that is NOT used for another food crop. You mentioned a 20% figure for human consumption. So we really do not require more corn for human consumption, but what about other crops for human consumption that are not being planted because of the subsidies for corn? This results in food prices going up. The fact remains that E85 production could not exist if it were not heavily subsidized by the US Government and produces a product that is 30% less efficient than gasoline. I submit that it would be better money spent for the Keystone pipeline, new refineries and incentives for diesel power plant production than to continue to subsidize an industry that produces product that harms millions of engines and has caused price increases in our food supply due to the large amounts of arable land that is required for mass production. Not to mention the pollution that results from the production of this product - which is something the "greenies" were touting ethanol would reduce in the early days. Also you cannot avoid the uncomfortable fact that the energy required to produce this product exceeds the energy it produces. How can this be a good thing? It is unsustainable.
