E85 gas vs. regular gas - Essay Example Today, E85 is produced from pole to pole and has a strategic role in energy policies of many countries (Kraemer, 2006, p. 128). This paper is to give a general overview of all pros and cons of ethanol use in America specifically. According to the Energy Policy Act of 2005, U.S. fuel suppliers, in the period of 2006-2012, have to increase the amount of added into fuel ethanol from 15 to 28 billion liters. Nowadays, for comparison, the United States consumes annually about 545 billion liters of regular gasoline. However, as a result of the Congress legislative initiatives, more than two trillion miles have been on traveled over, in last 25 years, on fuel mixed with ethanol. Most automobile companies increase production of flexible-fuel vehicles. As a consequence, most modern cars have automated fuel control systems allowing regulating air - fuel ratio sufficiently enough for simultaneous use of E85 and regular gasoline. For example, Ford, a leader in production of environmentally frien dly vehicles, has a range of Flexible Fuel - vehicles that run on E85, pure gasoline, pure ethanol E100 or any mixture of gasoline and ethanol (Focus, C-MAX, Mondeo, Galaxy, S-MAX, F-150, Ford Sedans Crown Victoria, Mercury Grand Marquis, Lincoln Town Car, Escape Hybrid E85) (Byrge & Kliesen, 2008, p. 5). Global interest in alternative (renewable) fuels was imposed, first of all, by different national environmental programs. It is known that the use of renewable fuels in a given region can reduce: †¢ Greenhouse gas emission - by 14 – 19% (9, 5 million tons of Ð ¡ÃÅ¾2 in 2008); †¢ Consumption of petroleum products - by 73 - 75 %; †¢ Use of fossil fuels - by 13 - 35 %. In addition to the environmental aspect, use of ethanol - gasoline mixes (E85) has the following advantages compared to regular gasoline: higher octane number, which means lower wear and increased life of a car engine; reduced vehicles’ service charges; lower cost of E85 at retail; product ion of ethanol supports national economy (agriculture mainly, processing industry and transportation inter alia) (Dale & Pimentel, 2008, p .22). But it’s totally wrong to consider that the use of ethanol has only advantages. Indeed, ethanol allows reducing pollution to some extent, since less carbon monoxide (CO) is emitted during its use. But, because of the high Reid Vapor Pressure, acetaldehyde and nitrogen oxides (NOx) are released, which produce more smog (Cunningham, 2007, p. 280). Companies, that manufacture and operate pipe lines, refuse to add pure 100% ethanol or ethanol containing fuels into their pines because of corrosion. So, starting from 2006, there is a constant shortage of rail-tanks for ethanol transportation. More and more fossil fuels (such as diesel and gasolin
