PENNSYLVANIA — Pennsylvania’s average gas prices have remained more or less stagnant over the past week, hovering about 20 cents higher than they were a year ago. The higher gas prices in the latter half of the summer have been driven by a decision to cut oil production by the Organization of the Petroleum Exporting Countries through the end of 2023. Lower refinery utilization rates have also led to slightly higher prices in the Midwest and other regions. The higher costs for gasoline were a significant factor behind the stubbornly high inflation rate in August.
States that have seen the largest increase in gas prices over the past week include Nevada, California, and Arizona, according to AAA.
