DOVER, N.H. (AP) – Gas prices are up again.

At the end of January, the average price of regular gas in New Hampshire was about $2.96. As of Monday, it was up 10 cents to $3.06.

There is no single reason for the jump in gas prices. A spokeswoman for AAA of Northern New England says a combination of factors are to blame, such as multiple outages at oil refineries in the country and geopolitical issues.

Rene Letourneau says fires have shut down oil refineries in Texas and Hawaii, and there have also been brief shutdowns at other refineries.

She says overseas, issues like Venezuela not selling crude oil to Exxon Mobil Corporation because of a legal dispute and the Organization of the Petroleum Exporting Countries considering cutting crude oil production, also affect the prices.

Joe Broyles of the New Hampshire Office of Energy and Planning says the key to high gas prices is usually the price of crude oil, which is now more than $100 a barrel.
