Ever since the oil shocks of the 1970s, the idea of energy independence, which in its grandest incarnation meant freedom from the world’s oil-rich trouble spots, has been a dream for Democrats and Republicans alike. It once seemed utterly unattainable — until the advent of fracking, which unleashed a torrent of oil. By early 2019, America was the world’s largest producer of crude oil, surpassing both Saudi Arabia and Russia. And President Trump reveled in the rhetoric: We hadn’t merely achieved independence, his administration said, but rather “energy dominance.”

Then came Covid-19, and, on March 8, the sudden and vicious end to the truce between Saudi Arabia and Russia, under which both countries limited production to prop up prices. On March 9, the price of oil plunged by almost a third, its steepest one-day drop in almost 30 years.

As a result, the stocks that make up the S.&P. 500 energy sector fell 20 percent, marking the sector’s largest drop on record. There were rumblings that shale companies would seek a federal lifeline. Whiting Petroleum, whose stock once traded for $150 a share, filed for bankruptcy. Tens of thousands of Texans are being laid off in the Permian Basin and other parts of the state, and the whole industry is bracing for worse.

On the surface, it appears that two unforeseeable and random shocks are threatening our dream.

In reality, the dream was always an illusion, and its collapse was already underway. That’s because oil fracking has never been financially viable. America’s energy independence was built on an industry that is the very definition of dependent — dependent on investors to keeping pouring billions upon billions in capital into money-losing companies to fund their drilling. Investors were willing to do this only as long as oil prices, which are not under America’s control, were high — and when they believed that one day, profits would materialize.
