There are a whole bunch of renewable fuels out there. I don't pretend to have a comprehensive comparison of the timelines for each, but one of the things about renewable natural gas is that, in many applications, it's available now. We've actually been using it for a number of years in different provinces, including yours, Mr. Zimmer. As you may know.... Well, you had Fortis two weeks ago, and they talked to you about this. There is a renewable natural gas option available.
The question, therefore, is not whether there is a technological hurdle per se. The question is this: Is there market demand, and will that trigger more supply and more technological innovation that will deliver more supply?
How does that compare to other renewables? I think a key point is to look at the full value cost when you're doing that. For any other renewable option, ask yourself this: Is there an existing delivery system in place? Is that delivery system already capable of taking on the fuels? Are significant expansions required? Are backup fuels required, etc.? You need to look at that kind of comprehensive analysis in order to make the assessment you're talking about.
We haven't done that comprehensive comparison, but I will tell you that we did make an aspirational commitment as an industry to 5% RNG in our systems by 2025 and 10% by 2030. We did that a number of years ago, and that's triggered all sorts of activity by our industry across the country. Our utilities are working—as the ones who spoke to you two weeks ago indicated—within their own regulatory frameworks to make sure that as much of that product can come to market as quickly as possible.
