Hi Klaire, You have asked an interesting question, which I will try to answer. I will assume that by fuel you mean ethanol, which can be used to produce gasohol. Gasohol in the United States is usually 90% gasoline and 10% ethanol. In some countries higher percentages of ethanol are used. To make ethanol, you need a vegtable that has a lot of sugar or something that can be broken down to sugar, usually starch. In the Unitied States corn has been the vegetable most often used to produce fuel. Some research has also been done using potatoes to produce ethanol. Other vegetables and/or grains with a high starch content could be used, but at the present time they are more valuable as foods. I hope this answers your questions. Sincerely, Al Bushway Professor of Food Science
