On that note, when you look at our ability to mobilize capacity, based on what our benchmarks are...and you've talked about how much carbon we're trying to eliminate, I guess, and certainly curtail, and how much we're putting into the atmosphere.
A couple of examples have been cited in terms of what European countries are doing. I was actually with Mr. Mills at a conference on energy last year in February in Washington. It seems to me that when you look at what all the countries around the world are doing, Canada has some comparative advantages in terms of technology.
From your experience and from what you've seen in terms of proven technology on the shelf that we could be not only using here but also, it seems to me, exporting abroad, which technologies can you point to that have been proven successful in curtailing the amount of carbon we're putting into the atmosphere? And which ones are most promising in terms of potential, that are maybe not refined but that look like they could have a lot of potential if we put more resources into them?
