Yes, and just to reinforce that, I think we do have a significant dilemma in front of us. On the one hand, we want abundant, cheap energy. We get blasted, too, for high gasoline prices anytime they go up. And we also want a clean environment.
To be honest, the only way to square that circle is with technology and innovation. In other words, it can't be the case that we just continue to produce and use energy the same way in the future as we have in the past. I think you do see those signs of innovation starting to come on to the market. I mean, ten years ago, hybrid vehicles were felt to be a dream, and now they really are penetrating the transportation market.
On the oil sands, I mentioned CO2 capture, which we're actively working on. We're also part of a consortium looking at deep geothermal energy. This is dry rock geothermal energy that would actually be emissions-free energy, and not just for the development of the oil sands; imagine it for central heat and power for our communities. This is drilling at tremendous depths, in the order of 5,000 metres to 7,000 metres. Again, it's very exciting as an opportunity, and we want to aggressively pursue that.
We're looking for the kinds of policies and partnerships with governments that are going to help encourage the investment that's needed to get there. It's not going to be done through punitive regulation and hitting us over the head harder. That's not going to be the motivator. It has to be a collaborative effort, a joint effort, and one where we really roll up our sleeves to make this happen.
