What Was the 1979 Energy Crisis?

The 1979 energy crisis, the second of two oil-price shocks in the '70s, resulted in a widespread panic about potential gasoline shortages, and far higher prices for both crude oil and refined products. Oil output declined by only 7% or less, but the short-term supply disruption led to a spike in prices, panic buying, and long lines at gas stations. 

Several states passed state-mandated gasoline rationing, including California, New York, Pennsylvania, Texas, and New Jersey. In these populous states, consumers could only purchase gas every other day, based on whether the last digit of their license plate numbers was even or odd. 

Understanding the 1979 Energy Crisis

The 1979 energy crisis occurred when the global supply of crude oil declined notably in the aftermath of the Iranian Revolution, which started in early 1978 and ended in early 1979 with the fall of Shah Mohammad Reza Pahlavi, the state’s monarch. In 12 months, prices almost doubled to $39.50 per barrel.

Key Takeaways

  • The energy crisis of 1979 was one of two oil price shocks during the 1970s—the other was in 1973.
  • Higher prices and concerns about supplies led to panic buying in the gasoline market.
  • Crude oil prices nearly doubled to almost $40 per barrel in twelve months.
  • The energy crisis of 1979 led to the development of smaller, more fuel-efficient vehicles.
  • OPEC's market share fell sharply and utility companies moved towards alternative energy sources.

Short-run disruptions in the global supply of gasoline and diesel fuel were particularly acute in the spring and early summer of 1979. In the U.S., the gasoline shortage also led to fears that heating oil might be in short supply through the 1979-1980 winter. This prospect was especially concerning for New England states, where demand for home heating oil was the highest.

It would be erroneous, however, to blame the crisis solely on the fall of the Shah. Notably, the U.S. faced more-acute pain from the crisis than other developed countries in Europe, which also depended on oil from Iran and other Middle East countries. Part of the reason behind the crisis had to do with fiscal policy decisions in the U.S.

In early 1979, the U.S. government regulated oil prices.  The regulators ordered refiners to restrict the supply of gasoline in the early days of the crisis to build inventories. The constrained supply directly contributed to higher prices at the pump. Another factor was unintended supply restriction after the Department of Energy’s (DOE) decided to make a handful of large U.S. refiners sell crude to smaller refiners who could not find a ready supply of oil. Because smaller refiners had limited production capabilities, the decision further delayed gasoline supply.

Monetary policy leading up to the crisis also seemingly played a role to a degree because the Federal Open Market Committee (FOMC) was reluctant to raise target interest rates too quickly. That, in turn, contributed to rising inflation late in the decade, and the jump in inflation was accompanied by higher prices for energy and a range of other consumer products and services.

Benefits from the 1979 Energy Crisis

Amid the crisis, politicians actively encouraged consumers to conserve energy and limit unnecessary travel. In subsequent years, the 1979 crisis led to the sale of more compact and subcompact vehicles in the U.S. These smaller vehicles had smaller engines and provided better fuel economy.

Meanwhile, utility companies worldwide sought alternatives to crude oil generators. Alternatives included nuclear power plants, and governments spent billions on the research and development of other fuel sources. As a result of the combined efforts, daily worldwide oil consumption declined in the six years following the crisis. Meanwhile, the Organization of Petroleum Exporting Countries (OPEC) global market share fell to 29% in 1985, down from 50% in 1979.
