I can start.
The objectives are certainly ambitious. We met people from 23 countries last week here in Ottawa. We talked about our collective challenges. Each of us feels the pressure of achieving the objectives and recognizes that it is imperative to do so.
The federal government's challenge is to work in partnership with the provinces because it recognizes that we will all have to meet our commitments when it comes to meeting the 2030 targets and those beyond. We are actually thinking about the targets that will follow that date.
The challenge is very real. There are uncertain factors, both upwards and downwards. The example of the fall in the cost of photovoltaic units was given earlier, this result being well above expectations in recent years. The same is true in the wind energy sector. Ten years ago, who would have said that costs would be so low, as was recently observed in Alberta or elsewhere in the country?
There are going to be some surprises on the upside, which are great, and other cases where we probably will have to struggle a bit more to get there. In the case of energy efficiency, I would submit that this is probably among the lowest, if not the lowest, cost solution we have. One of our principal challenges in developing these technologies is to make sure that they are affordable and that we go from availability to action and adoption. The collective challenge for us and our provincial colleagues is how to incentivize, how to bring along our firms and households to make the right investment decisions in retrofitting a house. In many cases, even though it may to their advantage to take action, they fail to do so out of procrastination or lack of tools. In my humble view, our principal challenge over the next 10 or 15 years will be to find the right solutions and act on them.
