A dip in gas prices in December has been offset with an increase this month. The Iowa Office of Energy Independence says the state’s monthly survey showed the price of ethanol blended gasoline in Iowa was $2.64 a gallon which is 56% higher than the January 2009 price of $1.82 a gallon.

The average price for diesel in the most recent survey was $2.87 a gallon, which is 23% higher than the January 2009 price of $2.34. State analysts say there’s been an increase in demand in Iowa and the rest of the U.S. with the cold weather, and prices have also increased with positive signs of recovery in the economy.
