After weeks of declines, the national average price of a gallon of diesel rose 7.3 cents for the week ended March 23 to $2.09. The price is $1.88 less than a year ago.
Since its record high of $4.764 announced July 14, the weekly national average has dropped $2.67, off 56 percent from the peak price. Before last week, the fuel price had declined steadily for several weeks as demand has weakened during the economic downturn.
For the latest week, average prices increased in all regions tracked by the U.S. Department of Energy except for New England, which remained the most expensive region at $2.40. The Midwest and Rocky Mountain regions have the cheapest prices.
