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.

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.

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

Compared to coal, which generates almost half the electricity in the United States, natural gas is indeed a cleaner, less polluting fuel. But compared to, say, solar, it's filthy. And of course there is nothing renewable about natural gas.
