WA Gas Prices on the Rise Again

Posted: Updated:

KENNEWICK, Wash.-- Gas prices are rising yet again.  The average gallon of gas in Washington has climbed nearly 20 cents in the past month, leaving many people asking, why?

It all boils down to supply and demand.  Since prices fell from last year's more than $4.00 a gallon high, more people have been hitting the roads, and more cars lead to increased demand.  The supply, however, has been going down.  The price of a barrel of oil has dropped to just $40.00.

The secretary for the Organization of Petroleum Exporting Countries, or OPEC, says many countries have had to cut new oil and gas production projects because of the low oil prices.

The average gallon in the Tri-Cities is $2.02.  In Yakima, the average is still just below $2.00, and the state average is $2.12.

Also contributing to the increase, late-winter and early-spring are common times for refineries to shut down for maintenance before the boom in demand during the summer, which also typically brings higher gas prices.
