The "common wisdom" is that Jimmy Carter was to blame for the gas crises in the 70s. Many use them as examples that Democrats can't be trusted on economic issues. But it's not that simple. Jimmy Carter got a bad rap!
There were two "oil shocks" in the 70s.
The first was the increase in the price in the fall of 1973. This was a result of Nixon devaluing the dollar and abandoning the gold guarantee. See the Chronology below.
The second was in the summer of 1979. It was the result of individually logical actions that were collectively irrational.
John Sterman, in Business Dynamics, Systems Thinking for a Complex World, includes an assignment Challenge (p. 212) on the oil shock in the summer of 1979. He explains what caused the long gas lines in the Instructors Manual, p. 82:
So, where did the gas go in 1979? The total inventory of gas in the system remained nearly constant. But the actions of nervous drivers moved the gas from below ground tanks at the corner gas stations to above ground rolling storage [in vehicle gas tanks].
The fear of shortages was a self-fulfilling prophesy that created artificial, speculative demand that caused lines and price increases. OPEC and President Carter were blamed, but we did it to ourselves.
So when many panicked and felt they had to top off their gas tanks, others saw the long lines and panicked, too. The extra volume of gas required to completely fill all the gas tanks of all the cars exceeds 2.5 days of supply in the supply line to gas stations.
The crisis should ease once the average car is nearly full ... [and] once deliveries ... are accelerated, every customer should be able to buy what they need.
Rationing schemes such as odd/even license plate rules or maximum purchase rules (e.g., 5 gal max.) ... [only reinforce perceptions] that the shortage is real and cause drivers to top off more often ... strengthening the positive loops and intensifying the shortage.
A much more effective policy is a minimum purchase of 10 gallons. You would have to pay for 10 gals whether your tank took it or not. ... Implementing such a counterintuitive policy would require great political courage on the part of government officials, but education about the dynamics of these self-fulfilling hoarding crises would help build public support. At the very least, policymakers should avoid imposing rationing schemes that only worsen the problem.

Chronology leading to the oil shock in 1973
The U.S. started the chain of events when Nixon devalued the dollar relative to the gold and finally abandoned the gold guarantee. The Oil Shock came when OPEC raised the price of oil to compensate. The increased price of oil rippled through the economy, causing inflation. The Fed raised interest rates to "fight inflation" causing the recession of the 80s and increasing the value of the dollar relative to foreign currencies (the Dollar Shock). This made imports less expensive and caused the Trade Shock; it was cheaper to manufacture products abroad and import them. Deregulation was another response to reduce costs (The Deregulation Shock); subtly and systematically, this resulted in a corporate culture where national interest was of decreasing consideration in business decisions. Hence our increasing economic and defense vulnerability.
A chronology of the 70s taken from Secrets of the Temple by William Greider (a great book):
August 15, 1971 President Nixon dismantled the Bretton Woods agreement. It had made the U.S. dollar the stable benchmark for all currencies (gold was $35/ounce).
December 1971 Nixon devalued the dollar by 7.9% (gold at $38/ounce).
Early 1973 The U.S. devalued the dollar by 11% (gold at $42/ounce).
March 1973 The gold guarantee was permanently abandoned.
Fall 1973 OPEC quadrupled the price of crude oil. William Greider wrote in Secrets of the Temple:
In the fall of 1973, six months after the dollar was permanently floated, OPEC quadrupled the price of crude oil. The OPEC price escalation was a direct and logical response to Nixons fateful decision. Oil trades worldwide in dollars and if the U.S. was going to permit a free fall in the dollars value, that meant the oil-producing nations would received less and less real value for their commodity. The dollar had already lost one-third of its value in only half a dozen years and seemed headed toward even steeper decline. In substantial measure, Saudi Arabia and the other OPEC nations were grabbing back what they had already lost and tacking extra dollars on the price to protect themselves against future U.S. inflation. The Wall Street Journal observed: OPEC got all the credit for what the U.S. had mainly done to itself. [WSJ, 1/30/86] The abrupt run-up of oil prices fed instant inflation into the price of everything else. Poorer nations that could not pay the bills borrowed heavily the recycling of petrodollars by major banks. Banks collected the deposits of revenue-rich OPEC governments and lent the money to developing nations so they could avoid bankruptcy and keep their economies growing.
1974 75 Recession. Unemployment peaked at 9.1%. Industrial production down ~15%. But when growth of the economy resumed, so did inflation. There was high inflation and high unemployment
both were not supposed to happen at once.
December 1978 buy now, pay cheaper inflation spiral in progress
79Q1 Inflation at 11%
Summer 1979 Gas lines, panic buying and topping off of gas tanks
Sep. 1979, late Fed tightened money, but vote split was 4-3, made markets nervous
skeptical that Volcker would halt inflation
Fall 1979 Speculation frenzy in gold and silver was rampant. Farmers encouraged to be leveraged in purchasing machinery and land. Speculators buying homes creating artificial demand. Builders see other builders constructing homes
the me, too syndrome. Volcker called this the froth of inflationary expectations.
