Yes, I think we're seeing a bit of a trend here. One of our early witnesses talked about the various types of home energy improvements or renovations and whether or not they were actually effective.
A lot of these are promised amounts. You even talked about the possible future benefits with higher prices of fossil fuels, as I believe you mentioned. A lot of this seems not to be based on “here was the bill before and here was the bill after” and what human activity changed in the sense of, “Well, now I can afford it, so I'm turning up my heat a little bit more and my savings are a little bit less,” versus somebody who's trying to be more frugal.
How do we go about getting better data to prove whether or not...? It's not to say that these technologies don't work but to say that the cost savings for individuals actually can be borne out, and we can say with confidence that on a yearly average you'll be saving this many dollars, especially when folks are trying to consider, as our last witness talked about, the potential of moving from 100 amps to 200 amps, where a heat pump being trenched in costs tens of thousands of dollars. I feel that it requires certainty for the individuals who are hearing these potentially big numbers.
Over time, the ROI is going to be good, but if they're going to do an analysis of their own home, with tens of thousands of dollars above and beyond the installation regardless of rebates for a heat pump, for example, how do we do a better job of having actual math showing whether this is going to be cost-effective for people participating in the program or just doing it of their own free will?
