###Input: To help reduce consumption, in 1974 a national maximum speed limit of 55 mph (about 88 km/h) was imposed through the Emergency Highway Energy Conservation Act. Development of the Strategic Petroleum Reserve began in 1975, and in 1977 the cabinet-level Department of Energy was created, followed by the National Energy Act of 1978.[citation needed] On November 28, 1995, Bill Clinton signed the National Highway Designation Act, ending the federal 55 mph (89 km/h) speed limit, allowing states to restore their prior maximum speed limit.

The energy crisis led to greater interest in renewable energy, nuclear power and domestic fossil fuels. There is criticism that American energy policies since the crisis have been dominated by crisis-mentality thinking, promoting expensive quick fixes and single-shot solutions that ignore market and technology realities. Instead of providing stable rules that support basic research while leaving plenty of scope for entrepreneurship and innovation, congresses and presidents have repeatedly backed policies which promise solutions that are politically expedient, but whose prospects are doubtful.

In 2004, declassified documents revealed that the U.S. was so distraught by the rise in oil prices and being challenged by under-developed countries that they briefly considered military action to forcibly seize Middle Eastern oilfields in late 1973. Although no explicit plan was mentioned, a conversation between U.S. Secretary of Defense James Schlesinger and British Ambassador to the United States Lord Cromer revealed Schlesinger had told him that "it was no longer obvious to him that the U.S. could not use force." British Prime Minister Edward Heath was so worried by this prospect that he ordered a British intelligence estimate of U.S. intentions, which concluded America "might consider it could not tolerate a situation in which the U.S. and its allies were at the mercy of a small group of unreasonable countries," and that they would prefer a rapid operation to seize oilfields in Saudi Arabia and Kuwait, and possibly Abu Dhabi in military action was decided upon. Although the Soviet response to such an act would likely not involve force, intelligence warned "the American occupation would need to last 10 years as the West developed alternative energy sources, and would result in the ‘total alienation’ of the Arabs and much of the rest of the Third World."

Although lacking historical connections to the Middle East, Japan was the country most dependent on Arab oil. 71% of its imported oil came from the Middle East in 1970. On November 7, 1973, the Saudi and Kuwaiti governments declared Japan a "nonfriendly" country to encourage it to change its noninvolvement policy. It received a 5% production cut in December, causing a panic. On November 22, Japan issued a statement "asserting that Israel should withdraw from all of the 1967 territories, advocating Palestinian self-determination, and threatening to reconsider its policy toward Israel if Israel refused to accept these preconditions". By December 25, Japan was considered an Arab-friendly state.

The USSR's invasion of Afghanistan was only one sign of insecurity in the region, also marked by increased American weapons sales, technology, and outright military presence. Saudi Arabia and Iran became increasingly dependent on American security assurances to manage both external and internal threats, including increased military competition between them over increased oil revenues. Both states were competing for preeminence in the Persian Gulf and using increased revenues to fund expanded militaries. By 1979, Saudi arms purchases from the US exceeded five times Israel's. Another motive for the large scale purchase of arms from the US by Saudi Arabia was the failure of the Shah during January 1979 to maintain control of Iran, a non-Arabic but largely Shiite Muslim nation, which fell to a theocratic Islamist government under the Ayatollah Ruhollah Khomeini in the wake of the 1979 Iranian Revolution. Saudi Arabia, on the other hand, is an Arab, largely Sunni Muslim nation headed by a near absolutist monarchy. In the wake of the Iranian revolution the Saudis were forced to deal with the prospect of internal destabilization via the radicalism of Islamism, a reality which would quickly be revealed in the seizure of the Grand Mosque in Mecca by Wahhabi extremists during November 1979 and a Shiite revolt in the oil rich Al-Hasa region of Saudi Arabia in December of the same year. In November 2010, Wikileaks leaked confidential diplomatic cables pertaining to the United States and its allies which revealed that the late Saudi King Abdullah urged the United States to attack Iran in order to destroy its potential nuclear weapons program, describing Iran as "a snake whose head should be cut off without any procrastination."
