After weeks of declining gas prices, Americans are again paying more at the pump with retailers charging an average of more than $2 per gallon in all but one state, AAA said Tuesday.

The nationwide average price of self-serve regular gasoline had dropped to a season low of $2.122 per gallon on Dec. 4, according to AAA's daily, online Fuel Gauge Report (www.aaafuelgaugereport.com), before reversing course and rising 5.8 cents to $2.18 per gallon as of today.
Energy demand created by cold winter temperatures and the approaching holidays were cited by AAA as primary reasons for the higher prices.
Today's nationwide average price compares to an average price of $1.866 per gallon recorded one year ago, the nation's largest travel organization said.
The highest statewide average price is in Hawaii at $2.64 per gallon. Motorists in Alaska are paying the next highest price at $2.503 per gallon. New Yorkers are paying an average $2.36 per gallon; the third highest state average price.
The lowest statewide average gasoline prices in the nation are in Utah at $1.998 per gallon, followed by South Carolina at $2.055 per gallon.

Self-serve premium averages $2.398 per gallon, down from $2.558 per gallon one month ago and up from $2.054 one year ago.

AAA's Fuel Gauge Report is based on data from Oil Price Information Service, the nation's most comprehensive source of petroleum pricing information.
AAA purchases the data and makes it available free on the Internet as a public service. Average daily prices for the nation, all 50 states and more than 250 localities are available for all grades of gasoline, making the site the most current and complete public source of fuel price information.
