The October 1973 Arab-Israeli war heightened geopolitical risk in a region central to global oil supply, setting the stage for producer retaliation against U.S. support for Israel.
The Organization of Arab Petroleum Exporting Countries (OAPEC) declared an embargo and coordinated supply cuts, triggering the first major 1970s U.S. energy crisis and driving sharp price increases and shortages.
In response to the crisis, President Nixon announced “Project Independence,” framing energy self-sufficiency as a national goal (often described as targeting independence by 1980).
Congress and President Nixon authorized the Trans-Alaska oil pipeline, a major domestic supply strategy intended to reduce vulnerability to import disruptions (though oil would not flow until later in the decade).
President Nixon signed the Emergency Petroleum Allocation Act (EPAA), authorizing federal allocation and price controls over petroleum products as an emergency response to the 1973 oil crisis.
Nixon created the Federal Energy Office to manage petroleum allocation and price controls amid shortages, appointing William Simon as administrator—an early step in building a more permanent federal energy bureaucracy.
After roughly five months, Arab oil producers agreed to lift the embargo on the United States, ending the immediate cutoff while leaving behind lasting price and policy effects.
The Federal Energy Administration (FEA) replaced the Federal Energy Office, institutionalizing federal authority to administer fuel allocation, pricing, and related emergency energy measures.
President Ford signed the Energy Reorganization Act, abolishing the Atomic Energy Commission and creating the Nuclear Regulatory Commission (NRC) and the Energy Research and Development Administration (ERDA).
Major oil-consuming countries created the International Energy Agency under the Agreement on an International Energy Program, aiming to coordinate responses to future supply disruptions (including oil-sharing mechanisms).
President Ford signed EPCA, which (among other provisions) authorized the Strategic Petroleum Reserve and created fuel-economy standards (CAFE), anchoring a long-term U.S. policy response to the 1970s shocks.
Amid severe winter shortages, President Carter proclaimed a natural gas emergency under the Emergency Natural Gas Act framework, highlighting that U.S. energy insecurity extended beyond oil.
Carter unveiled a comprehensive National Energy Plan emphasizing conservation, fuel switching, and institutional reform—an agenda that would drive major legislation and the creation of a cabinet-level energy department.
Carter signed the act creating the Department of Energy by reorganizing federal energy functions, aiming to improve coordination during shortages and support a coherent national energy policy.
The Department of Energy began operations as a cabinet-level department, consolidating disparate programs and giving the federal government a central institution for energy policy, R&D, and related security responsibilities.
Carter signed a package of major statutes (including PURPA, NGPA, NECPA, the Energy Tax Act, and the Fuel Use Act), reshaping electricity regulation, natural-gas pricing policy, conservation programs, and tax incentives.
The Shah’s departure from Iran preceded major disruptions in Iranian oil exports; the resulting global supply shortfall contributed to the 1979 “second oil shock,” again pressuring U.S. energy policy.
A partial core meltdown at Three Mile Island intensified public and regulatory scrutiny of nuclear power, influencing the political feasibility and oversight of nuclear expansion during the energy-security era.
With shortages worsening, Carter announced gradual decontrol of oil prices and proposed a windfall profits tax—an effort to encourage domestic production while addressing consumer and inflation concerns.
Carter formally proclaimed a national energy supply shortage and imposed federal conservation measures such as temperature restrictions in nonresidential buildings, reflecting the crisis-driven turn to demand restraint.
In a nationally televised address, Carter called for a large, long-term push to produce synthetic fuels from coal and oil shale, a centerpiece of the late-1970s strategy to reduce reliance on imported petroleum.
Carter signed the Energy Security Act, including the United States Synthetic Fuels Corporation Act, to accelerate alternative liquid-fuel production and other measures aimed at insulating the U.S. from future oil shocks.
