Yes, but first of all this is just the generation; it doesn't detail the emissions. There is an aspect in here that talks about carbon sequestration and what the effects would be if it were to be included in this.
In the triple E scenario, as I said, we put together what we thought was an aggressive policy package of different things that have been tried and used around the world, to help us do our modelling. In there is a carbon tax that's progressive over time and is included in this scenario.
All that is to say that when we do it again we'll probably have a little different configuration of the pie, and it may also be a little smaller.
One thing to note, though, is that we have a very strong momentum in this country and in the economy with respect to a hydrocarbon-based energy system. We have a lot of hydrocarbons, we use them, there's a significant investment made already in plants that are operating, and it would be difficult to change it.
