• On October 17, 1973, the Organization of Petroleum Exporting Countries (OPEC), a group of the world’s 12 leading oil-exporting nations, decided to reduce the amount of oil available to the United States. This “oil weapon” was used in response to U.S. assistance to Israel during the 1973 Arab-Israeli war (also called the Yom Kippur War).

    In one year, the price of oil in the U.S. increased fourfold, largely due to the embargo. Gasoline was rationed and drivers faced long lines at gas stations. In an attempt to conserve energy, year-round daylight savings time was implemented for 1974. Homes and businesses reduced energy use by turning off unused machines and turning out lights. The embargo caused a surge of interest in solar power, wind power, and other alternative energy sources.

    In 1974, OPEC announced the end of the embargo, and oil consumption in the United States went back up.
