Going Green - Vocabulary

Biodiesel - A domestic, renewable fuel for diesel engines derived from natural oils like soybean. It also reduces emissions of global-warming gases. Adding just 20% biodiesel to a petroleum-diesel blend cuts particulate matter by 31%, carbon monoxide by 21% and total hydrocarbons by 47%. Of course, using 100% biodiesel reduces emissions even more.
