Americans started thinking differently about U.S. dependence on imported oil 40 years ago this Sunday. Decades later, the U.S. is in the midst of a homegrown energy boom.
The oil embargo began in 1973. The United States had long taken cheap and plentiful oil for granted when Saudi Arabia shocked the country by suddenly cutting off all direct oil shipments in retaliation for U.S. support of Israel. Other Arab countries followed suit.
Prices soared. Gasoline lines stretched for blocks. Richard Nixon became the first of many U.S. presidents to call for energy independence.
