It's super attractive from a financial perspective. We need to make sure that Canadians act on it. We have a number of seven- and eight-year technologies out there that could be implemented very effectively and be attractive for folks to use. But we have to keep it simple, because people have their lives to live; they have kids to drive to soccer games, and energy efficiency is not the central focus of their life.
Third is to consider those who are out of range, as you have suggested, where the payback is too long to make it attractive from a financial perspective. We need to shave those costs and work relentlessly to do R and D and demo projects to bring down the cost so they become attractive. If people have an evolved conscience and are willing to pay extra money, that's terrific, but most Canadians will have to see a return in their pockets.
