To be a modern Republican in good standing, you have to believe — or pretend to believe — in two miracle cures for whatever ails the economy: more tax cuts for the rich and more drilling for oil. And with prices at the pump on the rise, so is the chant of “Drill, baby, drill.” More and more, Republicans are telling us that gasoline would be cheap and jobs plentiful if only we would stop protecting the environment and let energy companies do whatever they want.

Thus Mitt Romney claims that gasoline prices are high not because of saber-rattling over Iran, but because President Obama won’t allow unrestricted drilling in the Gulf of Mexico and the Arctic National Wildlife Refuge. Meanwhile, Stephen Moore of The Wall Street Journal tells readers that America as a whole could have a jobs boom, just like North Dakota, if only the environmentalists would get out of the way.

The irony here is that these claims come just as events are confirming what everyone who did the math already knew, namely, that U.S. energy policy has very little effect either on oil prices or on overall U.S. employment. For the truth is that we’re already having a hydrocarbon boom, with U.S. oil and gas production rising and U.S. fuel imports dropping. If there were any truth to drill-here-drill-now, this boom should have yielded substantially lower gasoline prices and lots of new jobs. Predictably, however, it has done neither.

Why the hydrocarbon boom? It’s all about the fracking. The combination of horizontal drilling with hydraulic fracturing of shale and other low-permeability rocks has opened up large reserves of oil and natural gas to production. As a result, U.S. oil production has risen significantly over the past three years, reversing a decline over decades, while natural gas production has exploded.
