A significant fact is that gasoline from petroleum has 115,400 MIDDLE EASTERN Thermal Units per gallon whereas alcohol (ethanol) has only 75,670 AMERICAN Thermal Units per gallon, or, alcohol has only .66 the energy of gasoline.
Oops! An INCONVENIENT TRUTH.
Where does much of that production energy come from? Oil. The American vs. Middle East comment is a myth.
Oops! An INCONVENIENT TRUTH.
There you go again Mr. Gore. This "fact" totally ignores that US gasoline comes primarily from North American Sources. BTW- Ethanol uses fertilizers that are petroleum based.
If the president was serious about this, we would have 50% of the auto's sold in the united sates converted to diesel and running on canola oil, and you could grown the rapeseed for the oil in less acres than is currently used for corn are close to that amount.
Metric system??
So if a plane in Europe crashes and it's reported that 110 people were killed then in the USA if the same plane crashed only 75 people would have been killed.

Your understanding of the energy balance (first law of thermodynamics) is severely limited or you didn't understand or read the article. Depending on the study, it takes anywhere from 70,000 MIDDLE EASTERN BTUS to 91,000 MIDDLE EASTERN BTUS to produce that 75,000 what you call american BTUs So in the worst case you're actually using more arab oil and in the other your getting a very marginal return. The papers I've read that show a 30+% increase do this by changing the way it's measured to include all of the by-products.
This is a bullsh.. way to measure it, since if you're producing it for fuel, then you're only entitled to measure the fuel output. The most optimistic studies based on the energy available show around a 6 - 7 pct net increase, and the less optimistic ones whow a 15% net decrease
