The 1973 oil crisis had a lasting impact on global energy policies, leading to increased investment in alternative energy sources, improved energy efficiency, and the establishment of strategic petroleum reserves. Countries worldwide sought to reduce their vulnerability to future oil supply disruptions.

On December 22, 1975, President Gerald Ford signed the Energy Policy and Conservation Act into law. This act aimed to reduce U.S. dependence on foreign oil by promoting energy conservation, improving energy efficiency, and establishing a strategic petroleum reserve.

The first International Energy Conference was held in Washington, D.C., in November 1974. It brought together representatives from major oil-consuming countries to discuss strategies for energy conservation, alternative energy sources, and reducing dependency on oil imports.

In June 1974, the International Energy Agency (IEA) was established in response to the oil crisis. The IEA aimed to promote energy security among its member countries through collective response measures and to coordinate energy policies globally.

The oil embargo officially ended on March 18, 1974, after negotiations and diplomatic efforts led by U.S. Secretary of State Henry Kissinger. The embargo's end was facilitated by promises of U.S. support for a peace settlement between Israel and its Arab neighbors.

In response to the energy crisis, the United States extended Daylight Saving Time from January 6, 1974, to October 27, 1974. This measure aimed to reduce energy consumption by making better use of daylight during the evening hours.

On December 25, 1973, Arab oil ministers met in Kuwait to discuss the ongoing embargo. They decided to continue the embargo and further reduce oil production, maintaining pressure on Western countries to change their policies regarding the Middle East conflict.

President Richard Nixon addressed the nation on November 7, 1973, outlining a series of measures to combat the energy crisis. He proposed Project Independence, aiming for U.S. energy self-sufficiency by 1980, and called for energy conservation and increased domestic production.

On October 17, 1973, the Organization of Arab Petroleum Exporting Countries (OAPEC) announced an oil embargo against nations perceived as supporting Israel during the Yom Kippur War. This decision led to a sharp increase in oil prices and marked the beginning of the 1973 oil crisis.

The Yom Kippur War began on October 6, 1973, when Egypt and Syria launched a surprise attack on Israel on the Jewish holy day of Yom Kippur. This conflict set the stage for the oil crisis as Arab oil-producing nations used oil as a political weapon against countries supporting Israel.
