The average national price for gasoline has held steady to start 2021, maintaining a price of $2.25 for the last 12 days, AAA said.

While the national gas price average is nine cents more than last month, January gas prices are already 33 cents cheaper than this time last year, AAA found. That is the largest year-over-year difference at the beginning of January since 2015.

Meanwhile, U.S. gasoline demand, as recorded by the Energy Information Administration (EIA), was at the lowest level for the last week of December in 23 years (since 1998) – at 8.1 million barrels per day.

“Holiday road travel was down at least 25%. With fewer people on the road, the majority of states saw little change at the pump from the last week of 2020 to the first few days of 2021,” said Jeanette Casselano McGee, AAA spokesperson.

At $2.17, 2020 saw the lowest annual national gas price average since 2016.

Following are the nation’s top 10 year-over-year decreases: Arizona (down 60 cents), Utah (down 53 cents), West Virginia (down 48 cents), Alaska (down 48 cents), Idaho (down 46 cents), Wyoming (down 43 cents), Colorado (down 42 cents), Oregon (down 42 cents), Connecticut (down 42 cents) and Vermont (down 41 cents).

Meanwhile, the nation’s top 10 least expensive markets are Mississippi ($1.92), Texas ($1.93), Missouri ($1.95), Louisiana ($1.96), Oklahoma ($1.98), Arkansas ($1.99), South Carolina ($2.01), Kansas ($2.01), Alabama ($2.02) and Tennessee ($2.04).
