While gasoline prices increased during the final days of 2013, the US Energy Information Administration is predicting the prices will fall slightly through 2014, in spite of the predictable seasonal increase during the summer. The agency is posting an annual average price for the coming year of $3.43 per gallon. Meanwhile, Spokesperson Amerine Woodyard says prices rose slightly over the last week throughout the US. She says the U.S. average retail price for regular gasoline rose to $3.33 a gallon on Monday — that’s up 6¢ from a week ago, based on the weekly price survey by the U.S. Energy Information Administration. Pump prices were highest in the New England region at 3.55 a gallon and lowest in the Rocky Mountain States at 3.10 a gallon. Here in Wyoming, the average price is $3.11 per gallon for unleaded regular according to AAA Auto Club’s Fuel Gauge Report which was within a tenth of a cent of Idaho’s statewide average. The average of the prices surveyed in Jackson Hole by Motor Trend is currently $3.23 per gallon and a penny more in Teton Valley, Idaho.
