I will perhaps make two points. The first one is that carbon capture and storage is associated with a transformation in Canada's energy system. When you look at the energy system, you're going to look at the exploration production as being the very front end, the refining, marketing, and distribution as the middle piece, and then you're going to look at the end use.
Carbon capture and storage is the transformational piece that takes us from where we are today with our energy supply of that three-pronged fork, if you will, to some other lower carbon energy future on the supply side. Then, when we start to look at some of the other technologies you're talking about--the consumption end, the user end--we have to have technologies that work there and also in the middle portion as well. Carbon capture and storage is the single largest opportunity on the supply side to make significant long-term reductions as we move to that lower carbon future.
