From the U.S. Energy Information Administration:
Across the country, retail prices for regular grade gasoline moved in tighter ranges in 2013 than in previous years. Changes in retail gasoline prices can be attributed to factors that include crude oil prices, refinery outages, inventory levels, and seasonal fuel-specification changes. Lower crude oil prices led to lower gasoline prices in 2013, with an average retail price of regular gasoline of $3.50 per gallon (gal) for the year, 11 cents per gallon lower than in 2012. Two regions in the country registered average retail pump prices below $3 per gallon for several weeks at a time during 2013. However, the weekly U.S. average price did not drop below $3/gal for the third calendar year in a row, reaching a low of $3.19/gal on November 11, and a high of $3.78/gal on February 25.
Rising crude oil production in the United States contributed to relatively stable global crude oil prices in 2013, at around the same annual average levels of the previous two years. West Texas Intermediate (WTI) spot prices averaged $98 per barrel (bbl) in 2013, up 4% from 2012 and the highest annual average since 2008. New pipeline and railroad infrastructure alleviated transportation constraints that had put downward pressure on WTI prices. The North Sea Brent spot price averaged $109/bbl, down 3% from 2012. Brent prices came under downward pressure as rising U.S. light sweet crude oil production reduced the need for U.S. imports, thereby increasing supplies of Brent-quality crude oil available to the global market.
