I understand that. I think there's research out there and I'm afraid I don't have it at my fingertips, but there is research out there that shows that's a bit of a misnomer in some cases, though not in all cases. We know that the energy it requires to produce the new product is significant, and quite frankly in Ontario the efficiency of the energy that's provided to run that device has in fact become a lot better. They've shortened that gap as well.
I think the advantage of replacing something because it's more energy efficient definitely is a factor, but not nearly as much as the cost of a repair to that device.
