Sisters School District recently purchased its first green-energy bus, fueled by propane gas. There is another bus on the way this month.
Propane is the world’s most popular clean-burning alternative fuel, reducing harmful emissions with 20% less nitrogen oxide, 60% less carbon monoxide and up to 24% fewer greenhouse-gas emissions, making it safer for the driver, the students, and the community.
The power and torque register about the same as a diesel-powered vehicle.
“The emissions are almost zero,” says driver Susan Waltosz. “Its just water coming out of the exhaust pipe! It’s so much quieter. You don’t have the rumble like you do with a diesel engine, and this bus turns on a dime.”
The tank size is similar in the propane bus as with its diesel counterparts: 100 gallons. The new Bluebird gets slightly lower mileage, at five versus six miles to the gallon on the diesel engines, but the new propane bus is a money-saver.
Running the same route as a diesel bus did last school year, the new propane bus will save the district pretty close to $5,000 (based on the secured rate for propane and a rebate from the EPA).
