Thanks to all of you for coming before us today. It's been very interesting.
I'm going to start with you, Ms. Hayter and Mr. Boyce. We had a witness here last week from Loblaws, and unfortunately I ran out of time when questioning him. He was talking about the big building/big box environment and how that could play into this energy efficiency world.
You mentioned smart grids and things like that, which could work. I know an electrical engineer, and he has told me that he's done work between American utilities and Walmart, for instance, to help integrate renewable energy into the system. When the sun goes behind a cloud in Tucson, a signal can be sent to Walmart to cut back on their air conditioning. I think he said that Walmart actually got a cheque from the utility for helping them to deal with that sort of situation.
Is that the kind of thing we can look forward to in the future with the large building environment especially?
