Natural gas is a better transportation fuel than gasoline, so if that's the case, it's cheaper, it's cleaner and it's a domestic resource.

Natural gas is the best transportation fuel. It's better than gasoline or diesel. It's cleaner, it's cheaper, and it's domestic. Natural gas is 97 percent domestic fuel, North America.

Natural gas is better distributed than any other fuel in the United States. It's down every street and up every alley. There's a pipeline.

The cheapest natural gas in the world is in the United States.

I don't care whether you use natural gas, ethanol, the battery. You can use anything, just so it's American.

You can't invest in natural gas on a daily basis. It's too volatile. But if you think of natural gas as a long-term holding, then you push your profit horizon out. A long-term time horizon would be at least two years.
