I'll comment on that.
A number of the studies we're undertaking now are with our largest urban centres, the City of Vancouver and the City of Surrey, and they are really taking a holistic approach to how they're doing their community planning. I don't think it needs to take 100 years, but I think some of our leading communities are taking a long view and doing their design charrettes looking out much further into the future to plan for and design for their renewable energy options.
We believe it can work in large urban centres. Most of our projects on the renewable energy mapping and design charrettes now are with large centres.
