Natural gas is a bridge fuel. But it's not a bridge - it's a gangplank. It's either a bridge in space or a bridge in time. The bridge in time we don't need. We have renewable technology right now.
What I want is natural gas to be a bridge to a cleaner energy future, not a dam against a cleaner energy future, not a dead end. To get this right, to get the most out of it, we not only have to make sure we exploit natural gas in a clean way - it's a challenge - but we also have to make sure that we are instilling and implementing all the incentives to win solar, nuclear energy efficiency that will make them continually competitive with natural gas in the future.
Relative to oil, however, natural gas is very cheap and very attractive. And I think that natural gas in emerging markets is very attractive. There is very little natural gas infrastructure in places such as China, where there is tremendous demand for natural gas.
Today, natural gas now outstrips coal as the leading provider of electricity in America. If this is as big as people believe it is, natural gas will soon be powering trucks and marine ships. Maybe even standard commercial cars that people use at home through compressed natural gas, other gas to liquids. The potential is there for more energy independence by America and a reliance on cleaner fuel - natural gas emits half as much as coal, in terms of carbon emissions. That's a real bounty.
We are, however, producing a lot of natural gas, which serves as a bridge to more renewable fuels. And I think that's an important transition.
We've recognized that natural gas would be the fastest-growing of the conventional fuels: oil, natural gas, coal. And so, we see the important role that natural gas will play globally and, more importantly, the important role it will play in the U.S. in terms of meeting future energy demand.
I was very bearish on natural gas for many years, pretty much from 2006 on. There was a tremendous natural gas bubble in the United States.
There's no question that natural gas is a lot better than coal or oil, in the sense that natural gas produces less carbon per unit of energy produced.
We do have serious energy needs for the country, we are aware that natural gas is especially in demand because of its air quality benefits: 90 percent of new power plants have been natural gas-powered.
Because America is the Saudi Arabia of natural gas. We have the world's largest reserves of natural gas, and the world's most sophisticated production and storage facilities, by a wide margin.
When you frack a well, you're exploding methane up into the atmosphere. So, Barack Obama, by supporting natural gas, and also talking about climate change is literally burning his own inaugural address. And he's doing it with natural gas.
Natural gas emits only half the carbon dioxide of coal when burned, but if methane leaks when oil companies extract it from the ground in a sloppy manner - methane is far more potent a greenhouse gas than carbon dioxide - it can wipe out all the advantages of natural gas over coal.
We are importing Russian natural gas which is not produced in an environmentally conscious manner. If the states that are blocking the pipelines were truly concerned about the environment, they would look to where the natural gas would be coming from.
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.
Natural gas is a very flexible source of energy that can help us bridge the gap between our current high-carbon economy and our zero-carbon future.
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.
