I think the biggest change has more to do with the price of crude globally than it does with one government or another. Going into the last campaign Liberals, Conservatives, and NDP had virtually identical policies for our sector, so there's been a fairly strong consensus around some of these issues in Canada, and I think there's a very strong consensus in the United States. It may have been the only issue that Senator Kerry and President Bush actually were competing to agree on during the last campaign.
There's a political consensus, but I think there's been a shift in the economics of our industry vis-à-vis the economics of petroleum as crude. Our costs of production are tied to agricultural commodities, which have been very stable; if anything, commodity price is declining slightly over time. Crude oil, the feedstock for our gasoline and diesel fuel, has obviously had a major shift in price. How bullish you are on our industry depends on where you think crude oil prices are going to be ten years from now. Some people think they're going to be double what they are right now; some people think they'll be $35 a barrel.
To the countries that are more pessimistic in terms of what the price of oil is going to be, investing in renewables seems like a very good idea. If you are a net energy importer like the United States or China or Brazil, there are urgent national security and energy security reasons for you to invest heavily in this industry.
Globally speaking, I think that's the biggest change in terms of why we are seeing our industry in such a dramatic growth period.
