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.
Recently, there has been a ton of debates about the pros and cons of using ethanol as a source of energy and a good replacement for gasoline. More specifically, according to the passage, the writer puts forth the idea that there are three conundrums of using ethanol as a fuel. In the listening, the lecturer is quick to point out there are some serious flaws in the writer's claims. The professor believes that ethanol is a good alternative for gasoline and not one of the reasons in the reading passage is convincing, and addresses, in detail the trouble with each point made in the reading text.
First and foremost, the author of the reading states that ethanol releases carbon dioxide in the atmosphere and does not have any environmental advantage. Some professionals in the same field, however, stand in firm opposition to this claim. In listening, such as the professor states that producing ethanol would remove carbon dioxide from the atmosphere. She goes on to say that ethanol is made of plants that would absorb carbon dioxide from the air as apart of its nutrition.
One group of scholars, represented by the writer, thinks that ethanol's production process would decline noticeably the amount of corn available as a source of food for animals. Of course, though, not all experts in this field believe this is right. Again, the speaker specifically addresses this point when he states that ethanol is produced from cellulose which is not eaten by animals.
Finally, the author wraps his argument by positing that ethanol price is high compared to the price of gasoline. Not surprisingly, the lecturer takes this issue with his claim by contending that in the future the demand for ethanol will increase. Thus, the production rate of ethanol will climb and eventually, its price will drop remarkably.
