Well, there's no substitute for petroleum for transportation fuel. As far as we can see into the rest of the century, motor vehicles will be fuelled largely by petroleum products.
As I mentioned earlier, we cannot control the global price of crude oil. It's often established by events outside our control, but we often say in this industry that the best cure for high prices is high prices, because they tend to bring on more supply and to induce energy conservation measures. Most of the time when prices have been high in the past—and we've just seen this in the last year—they have also tended to come down fairly quickly, because there's an immediate demand destruction caused by high crude oil prices and an immediate response from our industry, as best we can, to bring on new supplies.
I would ask you to tell your constituents that if they have some uneasiness with the development of Alberta's oil and gas reserves, particularly the oil sands, they should understand that allowing us to develop these sources of energy is the best hope we have in North America to ensure that we can be somewhat insulated in terms of security of supply, and also to be somewhat insulated in Quebec from prices of transportation fuels.
As I said, the best cure for high prices is often high prices, because they cause the demand destruction that brings down prices and they bring on new supply, which also has the same effect.
So if your constituents can be patient, they'll often find that if they wait a few months, prices will come down. It doesn't help our industry so much to have to live with that volatility, but there's often a corresponding period of lower prices to offset the high price spikes.
