There's nothing specific that I understand with respect to the oil sands, but I'm not an expert in that sort of financial aspect.
There is the accelerated capital cost allowance. Other people have suggested it's a subsidy, but as I stated earlier, it's simply a timing issue with respect to tax, and at a high price right now, the producers in actual fact, with the accelerated capital cost allowance, are being subjected to the tax and moving from the 1% to 25% royalty rate very quickly. That's why you're getting those very high numbers of government revenue—as a result of tax exposure.
I'm just trying to think. In the mining business, there is the flow-through share issue with respect to exploration. It doesn't affect the producers; it lines up future projects. It's only available to those who are in the non-producing side of the business, so it's not something that works for the producers—although I suppose in the long run you can say it does. But again, the draw to the treasury is quite minimal.
I think there's a different issue of incentives in trying to incent investment in alternative energy sources. That's quite a reasonable public policy. I'm not quite as pessimistic as Monsieur Ouellet about the timeframe in which we will see transitions to alternative energy sources in a significant way in the economy.
We're going to have coal and oil for a long time to come. The question is, are we going to have the clean coal technologies and the sequestration results that we need so as not to significantly damage or have an effect on climate. I think that's one of the real public challenges we face, because those will remain the primary energy sources.
We still need—and I don't mean to take away at all—to continue to develop wind and solar and address those issues of how we integrate them into the grids, etc. We're doing that in the mining business. We have some of our northern operations looking at wind farms to reduce the use of diesel fuel for remotely located mines. We want to take advantage of these new technologies as well, to reduce our carbon draw.
