Yes, and it's very similar to what was presented earlier about the home incentives and low-interest or no-interest loans that could drive some activity in this area. I think the same thing applies to the commercial environment. If you want to generate greater activity in energy efficiency, incentives are really good. Actually, no-interest or very low-interest loans would also help in this area to generate interest.
We're at a point in the built environment where the bulk of the buildings that exist today need to be dealt with in some form of renewal. That renewal could actually be a real opportunity to improve the efficiency of the operations of those buildings, particularly in the commercial area.
I think there are some real opportunities to bridge that renewal investment with energy efficiency investments to come up with buildings that will operate more effectively for what's going on in the interior—for the people or the processes inside—while reducing the waste of energy.
