Ethanol fuel, made from plants such as corn and sugar cane, has been advocated by some people as an alternative to gasoline in the United States. However, many critics argue that ethanol is not a good replacement for gasoline for several reasons.
First, the increased use of ethanol fuel would not help to solve one of the biggest environmental problems caused by gasoline use: global warming. Like gasoline, ethanol releases carbon dioxide into the atmosphere when it is burned for fuel and carbon dioxide is greenhouse gas: it helps trap heat in the atmosphere. Thus, ethanol offers no environmental advantage over gasoline.
Second, the production of significant amounts of ethanol would dramatically reduce the amount of plants available for uses other than fuel. For example, much of the corn now grown in the United States is used to feed farm animals such as cows and chickens. It is estimated that if ethanol were used to satisfy just 10 percent of the fuel needs in the United States, more than 60 percent of the corn currently grown in the united stated would have to be used to produce ethanol. If most of the corn were used to produce ethanol, a substantial source of food for animals would disappear.
Third, ethanol fuel will never be able to compete with gasoline on price. Although the prices of ethanol and gasoline for the consumer are currently about the same, this is only because of the help in the form of tax subsidies given to ethanol producers by the United States government. These tax subsidies have cost the United States government over $11 billion in the past 30 years. If the United States government were to stop helping producers in this way, the price of ethanol would increase greatly.
The reading passage and the lecture offer opposing views regarding the use of ethanol as an alternative to gasoline. While the author of the article presents three drawbacks of using ethanol as an alternative fuel, the professor in the lecture is of the opinion that the reasons in the article are unconvincing.
To begin with, the author argues that an increase in use of ethanol as fuel would add more carbon dioxide to the atmosphere, and thus would exacerbate the global warming problem. However, the professor claims that growing process of corns, to be used for ethanol production, would reduce carbon dioxide from the atmosphere. He mentions that those plants will absorb carbon dioxide, which is a nutrient for them, from the atmosphere; no added carbon dioxide would be released by introduction of use of ethanol as a fuel.
Secondly, the writer of the article suggests that foods for animals would vanish as corn and sugar cane plants would be used for ethanol production. In the article, it is said that cows and chickens live on corns, and using those plants for ethanol production would not leave sufficient foods needed for those animals. But the lecturer mentions that ethanol is produced from cellulose rich part of corns which are usually not used as food for animals. Thus increased use of those plants for ethanol production is not going to create food scarcity for those animals.
Finally, the lecturer argues against the idea of the passage that price of ethanol fuel would increase in future, which is going to frustrate the plan to use it as an alternative to gasoline. He believes that increase in plants production would eventually reduce the cost of ethanol fuel. According to him, price of ethanol would drop by 30% for three times of production as it is now of corns or such other plants.
