That is a description of one type of hybrid system that I mentioned in my presentation. Yes, I think those should be explored.
I also think—and I just want to build on something Allan said—that a federally coordinated approach might make sense, but we also need to recognize that the energy mix across provinces varies significantly. Where it might make sense to lower carbon emissions by promoting heat pumps in Ontario, British Columbia or Quebec, it would not make sense in Alberta, because you might be shifting people from natural gas, which is quite efficient, to oil- or coal-generated electricity as a fuel type for the heat pumps. We do have to have some variability based on the energy mix.
The other point I would make is about the commodity prices. The solace, of course, is that natural gas is currently at historic lows, but I think natural gas as a carbon-emitting source or fuel, relative to others, also has to be analyzed in terms of the impact of the carbon tax. The pricing will not remain where it is forever. In fact, the government has said that we have to change the pricing of these types of fuels, which will then create incentives for people to switch to other fuel types.
