In response to your first comment, yes, there is a gap between support levels for wind energy in Canada and in the United States. In Canada, support is 1¢ per kilowatt-hour production payment incentive. In the U.S. there's a 1.9¢ production tax credit. That does make the U.S. a more attractive market, I think, from an international investor perspective. I think we've seen a bit of the impact of that, for example, in terms of where some of the manufacturing investments are going in North America at this time.
There's no doubt that having a price on emissions will indeed have an impact. Obviously I can't, off the top of my head, provide you with “this much equals this”. But from our perspective, if you're looking at offsetting, for example, coal-fired generation, which is close to a tonne per megawatt-hour, the economics can change fairly significantly with a form of pricing on emissions.
