Groupe Robert set an excellent example by choosing natural gas for 150 of its trucks. The technology, however, isn't quite mature, so the return on investment isn't there yet. A natural gas-powered vehicle costs about $85,000 more. A company has to have substantial savings to make that kind of investment.
For our part, we are at the mercy of manufacturers. All we can do is buy what they want to sell us, and right now, that's diesel engines. However, the industry has made a real effort to reduce diesel use. There are what we call
side skirts on a trailer.
At the back, there are
the auxiliary power units.
There are also wide-tread tires. All of those mechanisms help reduce diesel consumption by up to 10% in some cases.
There are also the long combination vehicles I mentioned earlier. If that last 40-kilometre stretch of the highway were twinned, we would see more long combination vehicles, or double-trailers. Using a long combination vehicle is equivalent to taking one whole truck off the road.
Those are steps we are taking, but they have a price tag. In order for us to make an investment, there has to be a return. That said, if manufacturers start producing something other than diesel engines, there is no doubt someone will test it out and we'll see if it works.
