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.

First, the oil and gas business pays its fair share of taxes. Despite the current debate on energy taxes, few businesses pay more in taxes than oil and gas companies. The worldwide effective tax rate for our industry in 2010 was 40 percent. That's higher than the U.S. statutory rate of 35 percent and the rate for manufacturers of 26.5 percent.

Historically, the United States has had a wonderful energy policy. We're blessed with a diversity of resources. We have oil. We have gas. We have coal. We have nuclear. And renewables. And as a result, one of our biggest competitive advantages has been affordable energy. You need a strong economy and you need affordable energy to fuel that economy.

Price creates incentive, and energy will be developed if there's demand for it at the price you can develop it.

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.

Natural gas will displace coal in power generation. Getting natural gas into the transportation fleet is harder. It works best for vehicles that work from centralized fueling facilities like trucking fleets or buses and cabs. That is happening. Before it can make big inroads beyond that, infrastructure is going to need to be developed.
