Diesel Prices Soar To Nearly Seven-Year High In US

Diesel prices across the United States hit the highest national average since December 2014 during the week ending Sept. 27, according to the Department of Energy’s weekly report.

The U.S.’ average price for a gallon of on-highway diesel now stands at $3.406, up 2.1 cents over the previous week. This week’s price is the highest since the week ending Dec. 15, 2014, when prices averaged $3.419 per gallon nationwide.

Fuel prices have been steadily increasing since near the end of 2020. Prices fell to $2.372 during the week ending Nov. 2, 2020, and have since increased by more than a dollar.

Only two regions – the Rocky Mountain and New England regions – saw a decrease during the same week, with prices falling by 2.4 cents in the Rocky Mountain region and by a tenth of a cent in New England.
