My comment was on wind energy. Generally speaking, the subsidies to the other sectors have been much larger, both in Canada and in the United States, for the last 20 or 30 years. Generally speaking, I wouldn't say it's policy; it's economics and the lack of incentives.
Quebec is in an absolutely special situation with 30,000 megawatts, with reservoirs. The proposal for 15,000 megawatts that I mentioned was on territory where wind has been mapped by Environment Canada and some other private companies in the areas right around the reservoirs. What Quebec has as an advantage over lots of other places is that we have a grid and we have reservoirs that can take the wind when it blows and take the water when it's not blowing, so it is complementary. If you just leave it at that, it doesn't add to the total power, but that's the second step in the process. It's only in Quebec that it's policy rather than economics. The economics aspect is there right now.
I'll just add that Marylène Dussault can speak about the question of the environmental impact of the tar sands; she just can't talk about this particular study.
