Thank you, Mr. Egan, for that.
What's key to it all, and you brought it up earlier in your testimony, is that instead of adding a whole bunch of new infrastructure.... We talked about electrification and how good that can be in certain sectors, but, as you said, it's very costly, and we're not there yet.
I think what you brought up that was so critical to this conversation—and customers might disagree—is that natural gas is already a delivery mechanism that's affordable—we had this discussion with Fortis last week—but amongst all the energy forms, it's fairly low in terms of delivery.
You brought up existing infrastructure. I think that's the key to making this affordable. We already have pipes in the ground that go to people's homes to feed their furnaces and whatever else is used by natural gas, and I think that's the key to it all. This doesn't need to be remade overnight. We can use our existing infrastructure for many years. Our goal is to add 50% renewables by 2030. Certainly this enables us to metre up and dial it up as we go, rather than just bringing on a whole entire new system.
I don't know who to ask, Mr. Egan, whether it's you or Mr. Smillie, but with regard to the time to spool up for renewable natural gas for, let's say, the natural gas sector as opposed to spooling up the renewables in other sectors, timeline-wise what are we looking at, if you want to do a comparison?
