How different would the U.S. be if it were not energy dependent upon the Middle Eastern nations? It is estimated that the United States used over â€Å"18.6 million barrels per day (MMbd) of petroleum products during 2012†. (â€Å"How dependent are we on foreign oil?†) The U.S.’s dependence on oil has caused major difficulties regarding its military and economic status. However, biochemists in the U.S. have discovered new ways to decrease the U.S.’s dependence on foreign oil. By fermenting and distilling the sugars of corn, biochemists can create an organic compound called bioethanol (or denatured ethanol) that, when mixed with conventional gasoline, can be able to operate cars. Environmentalists have stated that ethanol may be more detrimental to the atmosphere than traditional gasoline. In addition, carmakers have noted that the use of ethanol may cause problems in cars’ engines. Does the benefit of America being energy dependent outweigh the speculated detrimental consequences of using ethanol? Ethanol is usually combined with traditional gasoline to create â€Å"gasohol† or gasoline and alcohol. â€Å"In fact, one-third of gasoline sold in the US is mixed with ethanol.† (Giametta) Adding ethanol lowers carbon dioxide emissions, according to the U.S. Department of Energy. Carbon emissions occur when the fuel combustion of the car is not fully completed. An incomplete combustion may yield carbon, carbon monoxide, and other chemicals. Ethanol is thirty percent oxygen. Adding oxygen yields a more complete fuel combustion; therefore, it would lower the amount of carbon emissions. There are two types of ethanol gas that can operate regular, unmodified cars: E10 and E15. E10 has a concentration of ninety percent gasoline and ten percent ethanol, while ... ...uction can get rid of waste and make fuel. [Also] From farm to car, cellulosic ethanol releases less greenhouse gas than gasoline (86 percent less) and corn ethanol (52 percent less than gasoline).†(Nasr) Cellulosic ethanol shows promising benefits, but it also has its own share of consequences. It, like corn ethanol, will significantly decrease a car’s mpg. Growing the biomass needed to create the ethanol is another matter at hand. Will the U.S. have enough land to grow enough plant biomass to satisfy the demand? Cellulosic ethanol emits greenhouse gases as well, so in reality, it doesn’t particularly solve the problem of greenhouse gases. Hopefully, in the near future, we will be able to mass produce an alternative fuel without any detrimental consequences, but until that time arrives, I believe that corn ethanol isn’t worth the financial and environmental risks.
