Roy Willis, president and CEO of the�Propane Education & Research Council, says schools that switch to propane-powered buses will see huge savings in their transportation budgets. He explains that a federal tax incentive used to promote the use of alternative fuels provides a 50-cent-per-gallon relief when using propane. On top of that, he states that just switching from diesel to propane will save schools roughly 50 percent in fuel costs, and 40 percent if switching from gasoline to propane.

Aside from the monetary benefits, Willis states that propane is mostly manufactured within the United States — which, he notes, provides a stable market for the fuel. And research is also ongoing to find renewable ways to produce the alternative fuel.
