There's a pecking order in terms of emissions, from nuclear to heavy oil and coal. And in each area there are technologies that will help decarbonize or capture and store carbon. So we have to move into those areas. That's why Alcan is advocating that the government provide the right kind of environment for investments in carbon capture and storage and clean-coal technology.
But our advantage is only an advantage if you look at the full cost of what you use from your resources. For many years Alcan took the cost of its hydro-electricity and said, we have lots of it; we'll make aluminum, and if we're not terribly efficient at using that energy, we're still going to be profitable. Today we have a system in place where we can't do that. We can't do it with power. We can't do it with water. So we are really looking at full-cost pricing so that we can be much more efficient, as you raised, in how we use the resources.
We have reduced, for example, the use of water. We have lots of water in Canada. We've reduced the use of water by over 90% in our industrial processes. But we did that because we believe that water has a cost.
