The national average retail price of a gallon of diesel fell 1.6 cents from last week to $3.309 for the week ending Monday, Dec. 17. The new price is still 70.3 cents higher than the same week last year, according to the U.S. Department of Energy. The average price now has been above $3 for a record 13 consecutive weeks.
Prices fell in all regions tracked by DOE except for the New England region, where prices increased 1.1 cents, to $3.581, which was the nation’s most expensive diesel. The cheapest diesel was on the Gulf Coast, where prices fell 0.5 cents to $3.245.
The largest decrease, 7.8 cents, was in the Rocky Mountain region, where prices fell to $3.319. The second-largest decrease, 2.5 cents, was on the West Coast, where week-over-week prices fell to $3.415. The smallest decrease, 0.3 cents, was in the Central Atlantic region, where prices fell to $3.511.
Tight supply, growing demand worldwide and “heightened geopolitical risks” are to blame for the high prices of diesel and gasoline, said DOE’s Energy Information Administration.
