When it comes to the affordability gap with respect to energy efficiency, there's not much of a difference in terms of high-price markets versus low-price markets, because we're really talking about additional costs of construction. What's driving prices in the larger urban centres is land prices and those kinds of things.
Still, when you add more costs to the price of a home, no matter where you are, especially in energy efficiency, it is more.... The usual argument with regard to energy efficiency is about whether the energy efficiency savings will offset those mortgage costs. To a certain degree, they do. When you hit the right levels and when you make the right smart investments, that is exactly what happens. It's a question of how fast you can go with the right technology so that you're not creating this affordability gap where something is still too expensive and the energy savings don't pay for it yet. Our message is, let's get there and let's work together.
To your point about how we get there, as Mr. Diamond was saying in terms of this de-risking side of things, that's huge on a builder's side too. There is actually an excellent program out of the Department of Natural Resources Canada. It's the LEEP program, the leading energy efficiency program. It has changed its acronym a couple of times. Basically, that whole program is about looking at emerging technologies and getting builders together and de-risking those technologies by allowing them to go out, try them out in their local areas and figure out what works and what doesn't. They come back and give an assessment not only to Natural Resources but to other builders in the area, as well as giving feedback to the manufacturers on what worked and what didn't work and how you can improve it.
That's the kind of thing we need to be working on to help evolve the technologies, de-risk them and get them into the marketplace so that we don't have those barriers in front of us.
