Perhaps I could add to that.
On the green resources mapping, I know we tend to focus on electricity, and looking for opportunities to generate electricity is slightly different. But if we look at these systems, when we talk about these things we're talking about integrating them with solar, with geo-exchange. Every piece of ground has some green potential to it.
I think that's the idea behind this. The whole country has those capabilities to various degrees, right across the board. You can map that together with opportunities that require electric generation. That is a slightly different piece of it, but it's about knitting them all together to come up with a solution.
You mentioned the oil sands. When you look at the full cycle of greenhouse gas emissions, from production to end use, and start measuring things that way and looking across, then you start to optimize the decisions, I believe.
