Thank you, Mr. Chair, and thank you to all the witnesses today for the really interesting testimony already.
I want to pick up on something that my colleague was just mentioning. There's a wide understanding out there that we're going to need biofuels and hydrogen to decarbonize some of the hardest to evade areas, such as freight shipping and others. One area that it's a little less clear on is buildings, where in much of our country we have existing infrastructure to deliver natural gas. Actually, this is one of our largest sources of emissions.
My question is maybe first for Dr. Jaccard and then Dr. Layzell.
In your opinion, are we better placed to introduce low-carbon fuels into this existing infrastructure, or are we better placed to electrify if we're focused on measures that are both most economically palatable to the consumer and that will create jobs along the way?
