This is Dick Rosenblum again. I think Connie mentioned some of the numbers in the webcast about how fast it's grown, but as an overview: It has been roughly doubling every year for the last several years, with a slowdown, to some extent, this year. And the exact numbers are actually in the slides and the webcast. The question of how high could it go and how fast is really, to some extent, unknowable for the following reason. It really depends on the economics of both our utility generation. For instance, if the cost of our generation, because we could get LNG in, goes down, the economics shift. If federal credits or state credits change over time, the economics can shift. If the rate structure changes, the economics can shift. So it's really interactive to a great many things, all of which are in flux and somewhat speculative. Having said that, if you think about rooftop solar, and I don't mean to be trivial, but just to break it down to a logical chain, first, you need a rooftop. So if you're a -- an apartment dweller or a condo dweller or a renter, for instance, you probably don't have the ability to put something on the roof. Second, you need the financial wherewithal to be -- to be creditworthy enough to support the investment whether it's leased or bought. And third, you need the desire to put it on your roof. To some extent, that would depend on the age of the roof and the type of occupancy you have. For instance, if you're a vacation occupant and only here a few weeks a year or a month a year, you probably don't have the desire to do that. So there are limiting factors that are pretty clear, and at some point, those dominate the trend.
