Just to recap, the numbers and the point about its being the largest fuel are taken from the National Energy Board's 2018 forecast from November, so they're not our numbers.
In terms of opportunities, we use almost no natural gas in transportation in Canada today. There's a real opportunity to bring together electricity, natural gas, hydrogen and other fuels in sort of a low-carbon strategy for transportation in Canada.
With regard to heavy duty vehicles, locomotives, marine shipping, that's where the sweet spot for natural gas is; it's with the larger engines. With regard to smaller vehicles—passenger vehicles, etc.—that's really where electricity has a strong role. Both fuels are developing technologies in those alternative spaces, but predominantly the thinking is that the passenger vehicles and the smaller vehicles are electric. The larger-horsepower, higher-end vehicles move to natural gas.
