New and efficient technologies for extracting oil and natural gas are increasing the supply of both fuels from North America. A few years ago, a business genius named George P. Mitchell helped offer such a gift. As Daniel Yergin writes in “The Quest,” his gripping history of energy innovation, Mitchell fought through waves of skepticism and opposition to extract natural gas from shale. The method he and his team used to release the trapped gas, called fracking, has paid off in the most immense way. In 2000, shale gas represented just 1 percent of American natural gas supplies. Today, it is 30 percent and rising.
John Rowe, the chief executive of the utility Exelon, which derives almost all its power from nuclear plants, says that shale gas is one of the most important energy revolutions of his lifetime. It’s a cliché word, Yergin told me, but the fracking innovation is game-changing. It transforms the energy marketplace.
The U.S. now seems to possess a 100-year supply of natural gas, which is the cleanest of the fossil fuels. This cleaner, cheaper energy source is already replacing dirtier coal-fired plants. It could serve as the ideal bridge, Amy Jaffe of Rice University says, until renewable sources like wind and solar mature.
Already shale gas has produced more than half a million new jobs, not only in traditional areas like Texas but also in economically wounded places like western Pennsylvania and, soon, Ohio. If current trends continue, there are hundreds of thousands of new jobs to come.
Chemical companies rely heavily on natural gas, and the abundance of this new source has induced companies like Dow Chemical to invest in the U.S. rather than abroad. The French company Vallourec is building a $650 million plant in Youngstown, Ohio, to make steel tubes for the wells. States like Pennsylvania, Ohio and New York will reap billions in additional revenue. Consumers also benefit. Today, natural gas prices are less than half of what they were three years ago, lowering electricity prices. Meanwhile, America is less reliant on foreign suppliers.
All of this is tremendously good news, but, of course, nothing is that simple. The U.S. is polarized between “drill, baby, drill” conservatives, who seem suspicious of most regulation, and some environmentalists, who seem to regard fossil fuels as morally corrupt and imagine we can switch to wind and solar overnight.
The shale gas revolution challenges the coal industry, renders new nuclear plants uneconomic and changes the economics for the renewable energy companies, which are now much further from viability. So forces have gathered against shale gas, with predictable results.
The clashes between the industry and the environmentalists are now becoming brutal and totalistic, dehumanizing each side. Not-in-my-backyard activists are organizing to prevent exploration. Environmentalists and their publicists wax apocalyptic.
Like every energy source, fracking has its dangers. The process involves injecting large amounts of water and chemicals deep underground. If done right, this should not contaminate freshwater supplies, but rogue companies have screwed up and there have been instances of contamination.
The wells, which are sometimes beneath residential areas, are serviced by big trucks that damage the roads and alter the atmosphere in neighborhoods. A few sloppy companies could discredit the whole sector.
These problems are real, but not insurmountable. An exhaustive study from the Massachusetts Institute of Technology concluded, “With 20,000 shale wells drilled in the last 10 years, the environmental record of shale-gas development is for the most part a good one.” In other words, the inherent risks can be managed if there is a reasonable regulatory regime, and if the general public has a balanced and realistic sense of the costs and benefits.
This kind of balance is exactly what our political system doesn’t deliver. So far, the Obama administration has done a good job of trying to promote fracking while investigating the downsides. But the general public seems to be largely uninterested in the breakthrough (even though it could have a major impact on the 21st-century economy). The discussion is dominated by vested interests and the extremes. It’s becoming another weapon in the political wars, with Republicans swinging behind fracking and Democrats being pressured to come out against. Especially in the Northeast, the gas companies are demonized as Satan in corporate form.
A few weeks ago, I sat around with John Rowe, one of the most trusted people in the energy business, and listened to him talk enthusiastically about this windfall. He has no vested interest in this; indeed, his company might be hurt. But he knows how much shale gas could mean to America. It would be a crime if we squandered this blessing.
