Can I just add to that, Mr. Chair?
I think this goes back to the question of whether technology is moving along or the price of oil is driving this. It is, indeed, both. Technology has advanced enormously in the last twenty years, as has the amount of research being done. I did say, in response to the question of whether we have looked at nuclear, that we have looked at it. I should be clear that the research was not done by the federal government.
We have seen emission intensity levels come down. We have seen use of water come down. We've seen a decrease in the cost, which has made it more economical to proceed with some of this work. So technology is moving ahead, and there's an enormous amount of technological research, much of it being done in Devon by Dr. Hamza and his group, but also all over the world. The question is whether the research and technological improvements can keep up with the growth of this resource. That's the challenge we're facing.
