It's the political cure-all for high gas prices: Drill here, drill now. But more U.S. drilling has not changed how deeply the gas pump drills into your wallet, math and history show.
A statistical analysis of 36 years of monthly, inflation-adjusted gasoline prices and U.S. domestic oil production by The Associated Press shows no statistical correlation between how much oil comes out of U.S. wells and the price at the pump.
If more domestic oil drilling worked as politicians say, you'd now be paying about $2 a gallon for gasoline. Instead, you're paying the highest prices ever for March.
Political rhetoric about the blame over gas prices and the power to change them — whether Republican claims now or Democrats' charges four years ago — is not supported by cold, hard figures. And that's especially true about oil drilling in the U.S. More oil production in the United States does not mean consistently lower prices at the pump.
Sometimes prices increase as American drilling ramps up. That's what has happened in the past three years. Since February 2009, U.S. oil production has increased 15 percent when seasonally adjusted. Prices in those three years went from $2.07 per gallon to $3.58. It was a case of drilling more and paying much more.
That's because oil is a global commodity and U.S. production has only a tiny influence on supply. Factors far beyond the control of a nation or a president dictate the price of gasoline.
