Environmentally conscious Susan has been told that a new electric car will only generate 6 grams of greenhouse gases (GHG) per kilometre but that a standard internal combustion car is double that at 12 grams per kilometre. However, tt nature ofelectric cars is such that the new technology and electric batteries generate 30,000 lbs. of GHG to manufacture and another 10,000 lbs. to recycle. Astandard car generates only 14,000 lbs. of GHG to manufacture, and recycling established technology is only 1,000 lbs.

"They're healthier, they're cleaner burning, and they're much quieter than the diesel option," said a school administrator. Propane-powered buses also reduce greenhouse gasses by 22% compared to gasoline-powered buses and 6% compared to diesel ones. But they come at a premium$103,000 for a propane model, $15,000 more than the diesel equivalent. The propane bus operating cost (above and beyond fuel cost) is 30 cents/kilometre, compared to 40 cents for the diesel. Diesel fuel costs about $2/Iitre, about $1 more than propane. Bus mileage is 12 kpl for the propane model vs. '10 kpl for diesel. The life of a school bus in the district averages 9 years, and each bus travels an average of 30,000 kilometres per year because the district is so large and rural.
