Careers in Biofuels
In 2010, there were about 250 million registered vehicles on U.S. highways.[1] Most of these vehicles have engines that use oil-based fuel, such as gasoline or diesel. Even hybrid-electric cars use gasoline to power their internal combustion engines, although they use less fuel than traditional automobiles.[2]
The use of oil-based fuels has both economic and environmental impacts. Both consumers and businesses are affected by fluctuations in oil prices. Fuel prices have been trending upward, with the annual average price of a gallon of gas increasing by about 170 percent between 2002 and 2012.[3] And vehicles powered by oil-based fuels release emissions that are harmful to the environment, including greenhouse gases (GHGs).
