Yes, there is a lot of evidence. Thank you very much for that question. It's an important one.
There is a lot of evidence that the programs are stimulating the uptake of emerging technologies and encouraging the integration of efficient technologies and renewable and other emergent technologies. I'll give you a couple of examples.
The home retrofit program has provided incentives to more than 1,000 domestic hot water systems in the residential sector and more than 7,000 heat pump systems, which provide both heating and air-conditioning. These are quite expensive technologies for the homeowner to adopt. The grant was very helpful, and I don't think we would have seen such penetration levels of those technologies without the incentive.
In other areas, we certainly see an impact on technologies. For example in the industrial sector, we have 19 benchmarking studies in different sectors of the economy that give information to the industrial plant managers and decision-makers about better technologies to put in their plants in order to bring the plants up to a benchmark efficiency level. We have evaluations of those to show that they're effective.
