Oil Prices: Cause and Effect








Why is crude oil so expensive? Why does it matter?

The price of crude didn't rise from $12 in early 1999 to nearly $60
because the world suddenly ran out of oil. On the contrary, the
world supply of petroleum has risen 10 percent since then,
according to the International Energy Agency (IEA), from 65.8
million barrels a day in 1999 to 72.5 million in 2004. Cambridge
Energy Research Associates estimates global oil production
capacity will increase at least twice that rapidly over the next five
years -- by as much as 16 million barrels a day by 2010.

 Oil prices did not quintuple after 1999 because Americans
suddenly switched from mini-cars to SUVs. On the contrary, if all passenger cars, pickups and
SUVs were replaced with bicycles, the United States would still import a lot of oil.

 We import nearly 58 percent of all petroleum, yet only 45 percent of each barrel is used to 
produce gasoline, and a significant portion of that gasoline is used in delivery vans and taxis.
Commuter and leisure driving accounts for little more than 40 percent of the oil we consume -- 
far less than the amount we import. The rest of each barrel of crude is used for heating oil 
and diesel fuel for trucks, busses, farm machinery and ships (23 percent), petrochemicals 
(17 percent), jet fuel (9 percent), asphalt (4 percent) and propane (4 percent).

U.S. industries use petroleum to produce the synthetic fiber used in textile mills making
carpeting and fabric from polyester and nylon. U.S. tire plants use petroleum to make synthetic 
rubber. Other U.S. industries use petroleum to produce plastic, drugs, detergent, deodorant, 
fertilizer, pesticides, paint, eyeglasses, heart valves, crayons, bubble gum and Vaseline.

When the cost of oil goes up, production costs are increased and profits reduced for industries 
that depend on oil. Producer costs -- not consumer gasoline costs -- are the reason high oil
prices threaten to shrink industrial production of goods directly affected and also of energy-
intensive products such as aluminum and paper. This threat affects all new and old industrial 
economies, whether those nations import or export oil. The United States may be least
vulnerable because of superior energy efficiency and a larger service sector.
