Thank you, Madam Chair.
I think it was Mr. DesRosiers who spoke earlier about the 2030 target and the fact that 75% of our housing stock is already there. We're speaking about retrofits, as Mr. Fast said. Some people will do energy retrofits because they're environmentalists and it's the right thing to do and the technology is there, but I think I'm safe in saying that the masses want a return on investment. With domestic solar panels, there was no really great return. With photovoltaic, there was no return based on cost. It's a chicken and egg thing.
Do you think that's where we can help, that it's the direction we should be looking at, to help the return on investment, to provide incentives to people to make these energy retrofits? If 75% of our housing stock is already built, and we need to hit those targets, unless you're seeing additional ways to accomplish those goals, the prices aren't going to come down that drastically, as they did with PV. PV prices came down probably 60% of 70% in the last eight or 10 years. Is that going to happen in this chicken and egg scenario? Do you see the costs of all of those energy retrofit technologies coming down? I'm looking at Frank, but do any of you have a comment on that?
