Well, I think if you look at natural gas in particular, the reason that the United States has significantly reduced greenhouse gas emissions on path towards those Kyoto goals of 1990 emissions rates, and it’s because of natural gas, because we have switched over a considerable portion of our electricity generation from coal to natural gas. And so we’re the only industrialized country that has seen significant drop in greenhouse gases, and it’s because of natural gas. So it’s definitely easy to square those two together, because the more natural gas we produce domestically, we can export it overseas, we can use it here at home, and it’s clean burning, and it reduces greenhouse gas emissions.
