It's a very good question. It's a very politically charged question because you're dealing with different regions within the country.
My view is that when we look at issues of energy use and climate change and these sorts of things, they go beyond provincial and national boundaries. If I save electricity, even in a region where that electricity is produced by hydroelectric power, that power doesn't disappear; that power is still being produced. That power can be sent to another region that is using coal fire.
I think the net effect all the way down will be that you will save fossil fuel and carbon emissions from it. I think that's why, as Thomas said, we can probably use an energy-intensity target and not get too hung up about how electricity here is produced differently from somewhere else. If we look at the whole country, there's a net benefit regardless of the region.
