The United States was a large producer of oil. In various states around
the country, oil is still being produced, but the volume of production has
dropped. In the 1970s, production peaked at nearly 10 million barrels
of oil per day making the United States one of the largest producers of
crude oil. Though new oil fi elds in Alaska and the Gulf of Mexico have
helped, the total production of domestic crude oil continues to decline
as oil wells become exhausted. The United States produces some 5.1
million barrels of oil per day, making it the third largest producer after
Russia and Saudi Arabia. (http://www.eia.doe.gov/neic/infosheets/

If the demand for crude oil was also decreasing at the same rate as
domestic oil production, then we would be fi ne. However, demand is
growing, and by 2025, it is anticipated that the U.S. daily consumption
of crude oil will top 20 million barrels of oil per day. The growth of car
ownership in the United States combined with the trend toward larger
gas guzzling cars and trucks has added to the problem. At the same
time, air travel continues to increase. Use of more effi cient rail travel is growing in certain parts of the country, but the rail infrastructure is not able to provide
an alternative to many people who want to travel.
