Of course there are many ways you can do this. I've been a promoter of the biogas, for example, that's generated from manure and other organic waste that can produce electricity, but of course it's very uneconomic to do at the present time. The reason they can do it in Germany, Austria, and some of those countries is because they have a law that requires electricity distribution companies to pay a very high price for electricity that is generated by biogas, in the order of 0.25 euros per kilowatt-hour.
If we have a plant in Alberta, they're getting only 6¢ or 7¢ Canadian for a kilowatt-hour. If we had a policy that paid them to do this, I think you would see an awful lot more, and you could get the feedlots and so on that could generate their own electricity from their own manure waste. But it would be very expensive. We can do this; it's technically feasible, but it's very expensive, and I don't sense that there's any lobby group to try to push this kind of a policy on the government.
I think it would certainly be a lot more environmentally friendly than a biofuels policy based on the use of cereal grains and oilseeds, and I think it would certainly not have the impact of taking food grains out of the food chain. I think there would be a number of advantages for it, but it's very expensive.
