Gas prices soared to a seven-year high, reaching a nationwide average of $3.42 as of Tuesday, according to data from the American Automobile Association.
That’s 16 cents higher than a month ago, or $1.31 more than a year ago, and 80 cents more than in 2019, according to AAA.
Given a typical 15-gallon gas tank, that means Americans are spending on average about $19.65 more each time they go to the pump, compared to the same time a year ago.
California continues to top the nation’s most expensive markets at $4.62 per gallon, followed by Hawaii ($4.33), Nevada ($3.95), Washington ($3.87), Oregon ($3.77), Utah ($3.72), Alaska ($3.71), Idaho ($3.69), Washington, D.C. ($3.61) and Illinois ($3.60).
Michigan experienced the largest weekly increase in gas prices at an additional 16 cents per gallon, followed by Ohio (+14 cents), Indiana (+11 cents), Arizona (+7 cents), New Mexico (+5 cents), Illinois (+5 cents), Minnesota (+3 cents), Oklahoma (+3 cents), New Hampshire (+3 cents) and Texas (+2 cents).
Gasoline demand has been steadily rising over the past few weeks and is the reason behind the price increases, AAA says.
The prices are likely to continue increasing if demand increases as supply constraints remain the same, largely due to decisions made by the Organization of the Petroleum Exporting Countries.
OPEC previously decided in July to boost crude output by 400,000 barrels each month until at least April 2022. The collective met in October and decided to continue the increase rate established in July rather than further boosting the supply to meet demand.
But some possible good news: daylight saving time may reduce gas demand, relieving some of the soaring gas prices.
“Not everybody loves changing their household clocks for the end of daylight saving time,” said Andrew Gross, a AAA spokesperson, in a released statement. “But the shorter days could lead to lower demand for gas. Drivers may head straight home from work to avoid the darkness rather than tack on side trips for shopping or errands.”
