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 and lecture are both about the fuel, Ethanol. The author feels that ethanol can never be a good alternative to gasoline and he had three reasons for his support. However, the professor contradicts all the claims made by the author. He is of the opinion that these explanations are faulty.
To begin with, the writer mentions that, the increased use of ethanol would not help to solve global warming. In the article, it is said that Ethanol, when used as fuel releases carbon dioxide and thereby traps heat. The professor refutes this by proposing that, ethanol is from plants like corn and these plants use carbon dioxide for photosynthesis. So growing plants for ethanol will reduce the amount of this gas from the atmosphere that is compelling.
Secondly, the author suggests that the production of ethanol decreases the number of plants available for uses as a potential source of food for animals and humans. On the other hand, the professor's stand is that the ethanol can be made from cellulose - which is the substance seen in the cell wall of plants. He ensures that this part of plant is not eaten by animals and thereby the animal feed will not reduce.
Finally, the reading posits that Ethanol can never be able to compete with gasoline on price. On the contrary, the professor argues that, if the ethanol production increase, it will in turn drops the price of ethanol. Consequently, more ethanol will be available to use.
