The myth of US 'energy independence'

In This Article:

With gasoline prices now topping $4 per gallon on average, a lot of American drivers feel like the U.S. energy economy is going backwards. Didn’t we used to be energy independent? How can gas prices get so high if the United States is the world’s biggest oil producer? What happened to the fracking revolution? And why do U.S. gas prices depend on oil supply from Russia, on the other side of the world?

The short answer is that America benefits greatly from domestic oil and gas production—but the nation is also dependent on foreign energy in ways no president can undo. In terms of all energy, combined—fossil fuels, nuclear power, renewables and so on—the United States began producing more than it consumes in 2012, as the first chart below shows. If you consider “energy independence” to be a net surplus of primary energy, from all sources, then sure, the United States is energy independent.

But fuels are not typically interchangeable. You can't run a car on nuclear power or switch your home heating source if one type of fuel gets more expensive. So it doesn’t make much sense, from a consumer perspective, to talk about all energy in the aggregate. Yet some analysts and politicians, including Presidents Obama and Trump, have boasted about energy independence as if a surplus of one type of energy can offset a shortfall of another type. Usually, it can't.

The United States is not oil-independent

With regard to oil, the main component in gasoline, the U.S. consumes more than it produces, and has for decades. Flatly stated, the United States is not oil-independent, and hasn’t been since the early days of oil production. There has been a big increase in U.S. oil output since 2008, due largely to the advent of hydraulic fracturing, or fracking. Fracking has downsides, including possible environmental damage from toxic chemicals used in the process and intrusive drilling operations in areas where there had never been oil or gas operations before. Still, it has catapulted the United States into pole position as the world's top oil producer.

U.S. oil production in 2019, the most recent peak, was 140% more than in 2008. That surge in domestic output has narrowed the gap between the amount of oil we produce and consume—but the gap was huge to start with and Americans still burn 38% more oil than U.S. drillers produce. The second chart above shows the difference over time.

As with oil, natural gas production has soared during the last decade, since fracking helps tap natural gas deposits, too. U.S. production of natural gas first exceeded consumption in 2017, and the gap has widened since then. In mathematical terms, you could say we're natural-gas independent, because we produce more than we consume. The third chart above shows that.
