Thank you. I know you've also spent a lot of time studying efficiency programs in the United States, and perhaps also here in Canada, and I'm wondering whether you could talk about the programs that have been most successful in encouraging conservation of electrical consumption.
I know that carbon tax may be one way of encouraging conservation, but recognizing that it's a politically difficult issue, and given that you've spoken to it already, perhaps you could talk about some of the other measures you've studied that might encourage conservation.
