A bit of CCP of which I'm not to swift. Some information. A rather long
read but some very good information about Ethanol Ethanol has a positive energy balance, meaning the ethanol yields more energy than it takes to produce it. It is an efficient fuel made through an efficient process. It takes less than 35,000 BTUs of energy to turn corn into ethanol, while the ethanol offers at least 77,000 BTUs of energy. Ethanol's energy balance is clearly positive. Research studies from a variety of sources have found ethanol to have a positive net energy balance. The most recent, by the U.S. Department of Agriculture, shows that ethanol provides an average net energy gain of at least 77%. One faulty, outdated study shows ethanol's net energy balance to be negative. That research uses fundamentally flawed, decades old data that is not valid considering today's efficiencies in agriculture and in ethanol production. brings the overall price down. The U.S. ethanol industry provides more than 4 billion gallons of fuel to our nation's supply each year. Especially when refining capacity is tight, a larger fuel supply means less price volatility. Removing ethanol from our nation's supply would mean we'd immediately need to find 3% more fuel – that would cause dramatic spikes in fuel prices. Ethanol's impact on air quality Using ethanol-blended fuel has a positive impact on air quality. Ethanol is an oxygenate, and that oxygen helps the fuel burn more cleanly and more completely - a cleaner fuel for cleaner air. Many areas of the country have used ethanol in order to meet EPA clean air standards with great results. Ethanol reduces the emissions of carbon monoxide, volatile organic compounds, and toxic air emissions. Ethanol's role in energy independence Ethanol is an American-made fuel that helps our country to be more energy independent. U.S. ethanol production provides more than 4 billion gallons of fuel for our country – fuel produced at home from renewable resources, fuel that doesn't need to be imported. Ethanol is not the only answer to America's energy needs, but it is part of the overall solution. Energy independence means having choices, and ethanol is one of those choices that can be made right here in the U.S. from renewable resources. Ethanol's impact on the economy Ethanol has a tremendously positive impact on our nation's economy. It creates jobs and increases revenues; increases farm income and reduces farm program payments; and decreases the amount of energy we import. The combination of reduced farm program payments and increased tax revenues adds at least $1.30 to the U.S. Treasury for every gallon of ethanol produced. This figure even takes into consideration the ethanol incentive program. (AUS Consultants, Inc.) Ethanol has a tremendously positive impact on the local economies around the plants themselves. Local people are employed; local crops are purchased to make the ethanol; and local tax bases are significantly expanded. An average-sized ethanol plant employs about 40 people with good-paying, high-skill jobs and provides spin-off jobs through local providers of goods and services for the plant. week's time. The Renewable Fuels Standard (RFS) The Renewable Fuels Standard (RFS) is a policy that would require an increasing amount of renewable fuels to be used each year. The RFS in the recently passed federal energy bill would slate 7.5 billion gallons of ethanol to be used in the U.S. by 2012. In 2004, the U.S. used 3.4 billion gallons of ethanol. The RFS would streamline the current patchwork of fuel regulations we have across this country. States, regions – and in some cases cities – have different fuel requirements, and the RFS would allow renewable fuels to be used where they make the most sense instead of forcing the production of all these "boutique" fuels. * * * * http://community.webtv.net/tassail/ThomPage |

OK, but how many BTUs did it take to grow the corn? Don't forget the fuel to plow, disk, plant and harvest the corn then the fuel for the silo heaters needed to dry it for shipment then shipping costs to collect the corn and take it to the distillery. One faulty, outdated study shows ethanol's net energy balance to be negative. That research uses fundamentally flawed, decades old data that is not valid considering today's efficiencies in agriculture and in ethanol production. brings the overall price down. Let's see the numbers. Removing ethanol from our nation's supply would mean we'd immediately need to find 3% more fuel - that would cause dramatic spikes in fuel prices. I was told that back in the 1970s so I tried "gasahol" - 10% methanol. My cars ran, albiet with less power, but I got almost exactly 10% less miles per gallon. That says the alchohol wasn't burning at all, that it was just an expensive filler, like mixing sawdust into hamburger. I used the first tank of the new ethanol-blended gas last week and got 15MPG instead of the usual 18-20. Ethanol's impact on air quality Using ethanol-blended fuel has a positive impact on air quality. Ethanol is an oxygenate, and that oxygen helps the fuel burn more cleanly and more completely - a cleaner fuel for cleaner air. Many areas of the country have used ethanol in order to meet EPA clean air standards with great results. Ethanol reduces the emissions of carbon monoxide, volatile organic compounds, and toxic air emissions. BS! Adding a small quantity any oxygenate to gasoline reduces the unburned hydrocarbons, but raises the cost of the gas and reduces mileage. We could also reduce unburned hydrocarbons plus improve mileage by raising compression ratios again. But that'd cause more nitric acid in the air. And thats why the law says engines must burn unleaded gas - because it forced manufacturers to lower compression ratios. And that in turn necessitated expensive and now ubiquitous catalitic converters and MTBE. Ethanol is an American-made fuel that helps our country to be more energy independent. That's great! Now all we have to do is get EPA to require that all new cars have 14:1 compression suitable for burning ethanol efficiently. Or course we'll have watering eyes and rotting drapes but less hyrocarbons. Otherwise, ........ |

So if ethanol can be sold for 1/3 the per gallon cost of gasoline you're at least in a break even position replacing gasoline with ethanol. The numbers I've seen indicate 1.5 gallons of E85 (the highest useable concentration of EToH) roughly equal one gallon of gasoline. Max |

How much BTU's to tramp around the world trying to find oil. How many dry holes. How many BTU's setting Rigs, pumping. transporting crews, Tankers transporting crude thousands of miles over the worlds Oceans; traveling one way with empty tanks, land transport to Refineries. Seaman's pay, Roust-abouts pay, Shipping terminals cost and their payrolls. I don't think a Farmer and tractor running a disc plow and a harvester will even come close to that cost. You inadvertently explain why ethanol is not the miracle cure you claim it is. The farmer and tractor. Pesticides to keep the bugs at bay, you know, petrochemicals. Energy needed to convert the corn into ethanol, currently not a very efficient process. At the end of the day, it still requires 1.1 gallons of fossil fuel equivalents to produce 1 gallon of ethanol at this time. A simpler analogy, would you invest $110,000 for a return of $100,000 and think it was a good investment? John Cairns |

I think that's a slightly different issue. As I understand it, what you're saying is that it takes 1.5 gallons of ethanol to provide the same effective energy output as 1 gallon of gasoline--strictly an energy output issue. The numbers I was talking about related to inputs to and output of the ethanol itself, and suggested that one used about 2/3 of a gallon of petroleum products to produce 1 gallon of ethanol. The numbers I've seen, with respect to cellulosic ethanol production, are far less. I tried to relocate the website, but had no luck. Max |

... Hey Piasano!! What an asinine reply! Go to Naples. So how much BTU's to plant the dinosaurs and convert them to oil. How much BTU's to tramp around the world trying to find oil.

Obviously less than we get from the gasoline or we wouldn't be doing it. These are private funds from hardheaded businessmen who wouldn't be wasting their money. OTOH the gummymint is subsidizing Ethanol. So again, how much energy does it take to get a gallon of Ethanol, including the energy to grow the corn, Vs the energy that gallon produces in an engine designed for gasoline?? Plus; it is a renewable source!! Who and how are you going to use to plant new Dino. and where are you going to get them;---- What else; Oh yeah, had to go back to see what else; Compress Ratio & Nitric Acid! No one said to change engine Compression. That's all in your mind, Vito. Just the same as your Nitric Acid. If we burn Alky or Gasoline will there be a change in the Nitric emission? Yes! Unleaded gas will burn and produce energy at well under 10:1 compression. Back in 1970 EPA forced mfgr.s to lower compression ratios to those levels to reduce the NOx emissions. OTOH cousin Enzo and others used compression ratios of 14:1 and more to very effectively burn Ethanol in their racing engines. It don't burn worth a crap in todays US motors. ETHANOL FOR E85 AND AMERICAN FUEL INDEPENDENCE Fine with me if you make it burn efficiently enough to be economically viable. My sympathy is with the farmers not big oil - except when my taxes are being handed to some lunatics who want to spend more to produce less energy. But the tree huggers will squall when they find out that the new emission levels are rotting their cloths, burning eyes and killing fish, not to mention making even worse holes in the ozone layer. |

The numbers I was talking about related to inputs to and output of the ethanol itself, and suggested that one used about 2/3 of a gallon of petroleum products to produce 1 gallon of ethanol. OK, but then I must burn 1.5 gallons (50% more) Ethanol to go the same miles as a gollon of gas so 2/3 x 1.5 = 1, ie it takes the energy equivalent of 1 gallon of gas to get the same energy as one gallon of gas out of Ethanol. Kind of like buying a bushel of seed corn then working one's ass off to plant then harvest it and only get one bushel of corn back. |

Pleeeese Robert,
How much energy is consumed to discover, recover, transport, refine and sell oil ? The cost is now at a point to encourage new sources, the politic of the day is just the icing on the cake. The world consumes 1480 Barrels of oil per second. Capt. Suzy 35s5 NY |

1480 Barrels per second!
I do believe that would fall under the heading; ADDICTION! http://community.webtv.net/tassail/ThomPage |
