The Unknown Fuel – Three out of four Americans do not know about this alternative non-toxic fuel.

Pumped up about cleaner fuel

More drivers are learning about alternative biodiesel

Biodiesel is all around us — in our ferries, buses, garbage trucks, passenger cars, tractors, Army trucks, sailboats and more — yet surveys show that only one in four people knows about this alternative, non-toxic fuel made from vegetable oil.

But biodiesel is poised for liftoff, and more people are discovering its benefits. About 30 million gallons of biodiesel was produced and used in the United States last year — a sixfold increase in just five years.

The fuel runs in diesel engines but emits 78 percent less carbon dioxide, nearly 50 percent fewer particulates and 80 percent to 90 percent less of compounds linked to cancer than diesel, and fewer greenhouse gases than gasoline. (Engines using it do emit more nitrogen oxide, a smog-forming component.)

For the first time, an American company has made a car — the 2005 Jeep Liberty — designed to run on a 5 percent blend of biodiesel (B5). John Deere said it will start shipping all of its tractors and combines to customers filled with B2, a 2 percent biodiesel blend.
