With respect to the first question, our electricity prices in Canada are among the very lowest in the world. We have very rich hydro resources that contribute to that.
With respect to the emerging technologies wind, biomass, what we call small hydro, and those sorts of things--and some of them are what I would call a little further out, such as photovoltaics, and on the technology side, fuel cells--the cost of these has fallen quite dramatically over the last 15 or 20 years or so. Wind is a terrific example of that. You can actually see the technology. The turbines are getting bigger, with a bigger sweep, and there's more technology being introduced for how the blades adjust to wind speed and that sort of thing. There have been advances in wind forecasting. It really depends quite a bit on the specific circumstances, but if you take the amount of energy that's produced from it, wind is quite often competitive. One of the big difficulties with wind--it's an intermittent source, as some of the other emerging technologies are--is integrating it into a grid so that it's reliable.
Even in that respect, advances are being made. That is one of the reasons we see this tremendous growth. Canada reflects what's really going on in the world. It seems we are getting fairly close to that point where it's competitive.
I was saying a little earlier that it also depends on the other sources available to you. Hydro and wind have great synergy. If you have a capability to store hydro, then when the wind is not blowing you can use hydro. It's a fairly simple example, but I think it also helps to improve those economics.
