The embrace of new technologies to extract oil and natural gas at an unprecedented rate has transformed one of America’s enduring vulnerabilities into a strategic asset. Thanks largely to fracking — hydraulic fracturing of rock — the United States is now the largest producer of oil and gas combined in the world. America consumes large quantities of energy, so this expanded production has not yet made the country energy independent. But it has greatly decreased its dependence on foreign energy: About a decade ago, the United States imported nearly two-thirds of the oil it consumed; that percentage is now closer to one-fifth.
.. an improved trade balance and a stronger economy. The boom has also improved the country’s sources of soft power, in part by underscoring America’s enduring edge in innovation and ingenuity.
.. American producers of oil from shale rock have introduced a new business model to the scene: Small investments in exploration and production can bring oil to the market quickly. This weakens OPEC, by making it more difficult for its production cuts to result in sustained increases in oil prices. For the first time in more than a century, the market determines the price of oil with much less influence from any cartel, commission or band of big oil companies.
.. The energy boom has also weakened many of America’s competitors, particularly Russia, by both decreasing its revenues and reducing its ability to use its energy resources as a political cudgel.
.. The boom also expands opportunities for the United States to forge new partnerships. For instance, given China’s growing dependence, and America’s waning reliance, on Middle Eastern oil, Beijing may be more likely to work with the United States to stabilize that part of the world. Such changes put America in a stronger position to reinforce the international order.
.. Many non-energy policies of the Trump administration undermine the energy boom and all its potential advantages.
.. On climate, Mr. Trump’s pledge to withdraw the United States from the Paris agreement could also hurt the American energy boom. Natural gas stands to gain as the world takes strides to tackle climate change: As countries transition to more sustainable energy, they often move away from coal to natural gas. American natural gas exports could benefit from this transition — but not if countries like China and India also weaken their commitment to tackling climate change and drag their heels in curbing coal consumption.
.. Mr. Trump’s talk of retrenchment overseas has made friends and foes nervous about America’s willingness to continue to use its vast sea power to maintain open shipping lanes. Over half of the world’s oil supply and a growing percentage of the natural gas it consumes is transported through these waterways.
.. Mexico is by far the largest foreign consumer of American natural gas — a trend that will increase with recent Mexican electricity reforms. Yet President Trump’s talk about a border wall has spurred a revival in the presidential candidacy of Mexico’s own populist, Andrés Manuel López Obrador, who is committed to reversing these and other energy reforms. That would not only shrink the largest market for American natural gas but would also dull prospects of the United States, Canada and Mexico of reaching North American energy independence.
