In terms of smart grid, the federal government is playing a role in certain areas through support, say, for Sustainable Development Technology Canada and some of the investments they have. As well, we work with the Standards Council of Canada in trying to harmonize standards per smart grid equipment.
There are a number of areas. NRCan is supporting it as well, recognizing that energy, in this case in electricity specifically, is with the provinces. It can be a bit of a challenge to bring everyone together, but I would say that the smart grid in general is an area where there is a lot of cooperation and a lot of movement, and where people are learning from each other.
The issue of the smart-zero or net-zero home usually means that they have some form of solar in there as well, which produces more than what they use in a year, but not every time they need electricity. It still needs a grid to support it and it's still at a cost well above what conventional programs or conventional generation can produce.
One of the challenges overall is that the price of electricity, the price of energy, notwithstanding what the manufacturers all think, is actually relatively cheap, which makes it more difficult sometimes for energy efficiency, although I would say that my experience is that all the manufacturers, all the industrial facilities, really put in a lot of effort to be efficient.
It tends to be when we get to some commercial buildings, although even they are moving.... But individual people and their houses and how energy efficient they are when it.... You know, to save a few kilowatt hours doesn't really cost that much. The average cost of electricity per day for a residential user is anywhere from $3 to $6 per day.
