| Conventional gas delivers more energy than a gallon that contains ethanol, says the Kansas City Star. For instance: A gallon of ethanol has 76,000 British thermal units while conventional gasoline has 115,000 Btu. A blended gallon of gas that contains 10 percent ethanol gets 111,100 Btu. That amounts to a 3.4 percent reduction in energy, which over the course of a year of normal driving would take an additional 40 gallons of E-10 to go the same distance as conventional gas. If it's E-85, a blend containing 85 percent ethanol that can be used in specially equipped vehicles, the energy loss soars and more than offsets its lower cost, even though E-85 is about 60 cents per gallon less at retail than conventional gas: Mileage can suffer by about 25 percent with E-85, according to AAA. Over the course of a year, that amounts to an extra 300 gallons of E-85 to go the same distance as when using conventional gas. That means an average household, when the total cost of conventional gas and E-85 are compared, would spend nearly $100 more per year for E-85. To those that have the flex-fuel vehicles that can use the fuel, it's tempting to purchase E-85 because at first glance it appears to be a great deal compared with conventional gasoline. But at least for now, it isn't, says the Star. For example: AAA now calculates a price for E-85 to adjust for its energy content. The national average pump price for the fuel on April ... |
