  1. Ethanol: A good replacement for Gasoline? By: Christopher Joyce Jan. 2006 http://www.npr.org/templates/story/story.php?storyId=5173420

  2. Ethanol • With gas prices skyrocketing lately, many corporations are doing research for alternative fuels. • About 1 in 40 cars in the US can run on a mix of ethanol called E85 which is 85% ethanol and 15% gasoline. • Ethanol is an alcohol made from distilling the sugars in crops – primarily corn in the U.S.

  3. Why Ethanol? • Ethanol is being marketed as an alternative fuel due to the high prices and limited supply of oil whereas there is a hypothetically limitless supply of ethanol. • The US also would like to reduce its dependence on foreign oil. • Ethanol greatly reduces CO (Carbon Monoxide) emissions.

  4. The Debate • Critics say that there is more energy used in producing ethanol than is gained from it. • Even if all of the U.S.’s current corn supply was recruited for making ethanol, that would only produce less than 10% of the amount necessary for our transportation needs. • The environmental consequences of ramping up pesticides to produce large-scale biofuel crops also must be considered.

  5. Analysis Price D1 D0 S0 • The demand for ethanol as a replacement will decrease the demand for gasoline, causing gas prices to drop. P0 P1 Q1 Q0 Quantity
