As I said, the RFS opens the marketplace and it provides options for consumers. The energy market today is not an open market, so the RFS would lead, from our perspective, to opening the marketplace. It provides more options for consumers. There are more competitive options and more competitiveness in the marketplace.
I think that's the primary role of the RFS, and that's why I said that to stimulate innovation we need to continue to open the marketplace. We have an opportunity to increase the RFS, given that we can have more biofuel in our current fleet of cars.
Ethanol, in the last two or three years, has been cheaper than gasoline, so it provides a competitive option for consumers.
I think in the infrastructure we need more options. We need to open the marketplace by having more options at the pumps. This is really to provide options to customers. It's really in that sense that I think regulations can play a role in our market and stimulate innovation.
The reason we have Enerkem today is that it's been driven by the demand that the RFS has created in both Canada and the U.S. Without opening that market, I don't think you would have stimulated innovation as much as you have today.
