Well, if we look at the example of some of the specific areas where this would apply, we're talking about regions of the country that rely heavily on thermal resources for their electricity generation. We are talking about investments already in existing plants that are running and have been running for quite some time. In a number of those regions we don't have alternatives to the thermal generation that is currently there. The technology to be able to convert electricity generation to something that does, on a large scale, capture carbon is not yet economic. We do not yet have demonstration projects that are doing it on that scale. We are attempting to do so, but we're not yet at that point.
