We're starting to figure out how much more natural gas there is out there than people estimated. An absolute revolution in technology in the past few years has been in this shale gas development... Nuclear has taken it on the chin in the last month or two, but nuclear isn't going anywhere.
I think the long-term view is that we've had problems with the [nuclear] technology from the '50s, '60s, and '70s. There's different technology today, and I think it's going to be around. And don't count out oil. There is a lot of oil out there. There is a lot of oil yet to be found. And there's a lot of oil that's going to stay in the system for many decades to come. And when you look at it in the year 2031, I think that you'll see perhaps up to 10% of the world running on what we consider alternative energy, alternative fuels, things like that. But I think that the main base of energy and of power to run things is going to be what we have today, natural gas, oil, and coal, with nuclear.
And lots and lots and lots of different technology in how it's produced, how it's distributed, how people use it, efficiency, conservation, things like that.
