Abstract: . . .  fuel can also be replaced by biodiesel made from vegetable oils! In the United States, this fuel is now being produced from soybean oil. However, any veg- etable oil—corn, cottonseed, peanut, sunflower, or canola— could be used to produce biodiesel. Researchers are also developing algae that produce oils, which can be converted to biodiesel. The most commonly used biofuel in the United States is ethanol, which is produced from corn and other grains. A blend of gasoline and ethanol is already used . . .

For example, the water below the dam is often colder than what would normally flow down the river, so fish some- times die. The water level of the river below the dam can be higher or lower than its natural state, which affects the plants that grow along the riverbanks.
