Actually, I'm a strong supporter of comprehensive tax reform.

About 75% of the price of gas is really dictated by crude oil. At the heart of the issue is increasing demand over a period of many years around the world. World crude oil consumption now is close to 90 million barrels a day. Most of the growth in demand is coming from China and the developing world.

If you look around the world, the countries with the best environmental practices are the wealthiest. There's a reason for that. If you're worried about where your next meal is going to come from or shelter over your head, your focus is on those things.

Chinese growth will either be strong or very strong. They have a voracious demand for energy that will only continue to grow. What they're doing... is looking at all forms of energy. They're going ahead very strongly with coal, nuclear, oil, natural gas.

What I see are people who want affordable energy. They want strong environmental standards - they want a lot of things - but first and foremost they want affordable energy. And if you want affordable energy, you want oil, gas and coal.
