There is some work being done on energy efficiency standards, but I would say it doesn't go fast enough.
To answer your question, and also to come back to one of the previous comments, if we were having this discussion when I first went to one of these meetings in 1994, I would have asked, “Do we do this or that?” To echo Isabelle, at the moment we have to do energy efficiency and carbon pricing and investments in public transit. We have to do all of these things. It's not whether we do this or that. We need them all, and energy efficiency is one of the cheapest and easiest reductions.
Some of the proposals include aiming for a net-zero building code by 2025. A building built after 2025 has to produce as much energy as it uses. You can only do that with significant improvements in energy efficiency, but also by having wind and solar installations, etc.
We need that whole package, and efficiency is a big part of it. If I replace my incandescent bulb with an LED that does the same job and uses 5% of the electricity, I can still read my book. I'm happy and I'm using so much less energy that it's a lot easier to get it from clean sources.
Those are the kinds of investments we need to make. We need to help turn over that capital stock, and we really need tough codes and standards to ensure that anything new that's coming out into the marketplace is the very top of efficiency.
