In a April 7 letter from API President Red Cavaney, API explains to Congress the factors contributing to higher gasoline prices. These factors include continued geopolitical concerns in key oil-producing regions; the lingering impact of last summer’s hurricanes on refinery and oil and natural gas production and the challenges presented by the end of the oxygenate mandate. “The only short-term answer to our energy situation is for government to join with the industry to encourage the wise and responsible use of energy by all consumers,” Cavaney wrote in his letter.
