We definitely think that's an important category for the reasons you mention. It isn't just because doing renewables is a good thing; it's actually because doing them is profitable and drives productivity benefits.
For the electricity grids, we're looking at clean tech in innovation. We just don't know why in Canada we're not a powerhouse on clean tech, in everything from how we use our existing energy resources.... I think we see that with some of the Canadian energy companies, such as COSIA and what it's trying to do. We think a lot more can be done on that front. We're looking, for example, at solar for greenhouses for food in the Prairies. Infrastructure is going to be required to build the greenhouses that would allow for more crops. That's not just good for the environment; it's good for productivity growth, and it is a renewable resource. Water systems are another very important category. I could go on.
