Nevadans are paying 20 cents more for gas than they were a year ago, according to the AAA.
The Silver State's average gas price is $2.94, a five-cent increase from last month's gas price survey. The average price for gas in November 2009 was $2.74.
Carson City saw a six-cent increase over last month's survey to $2.92. In Reno, prices went up eight cents to $3.07.
"Oil stockpiles are at their highest levels in six months, but pump prices aren't dropping, thanks in part to a lack of gasoline reserves," said Michael Geeser, a spokesman for AAA in Nevada. "This lack of gasoline supply is being attributed to autumn maintenance at oil refineries across the country, which has cut down on how much gas they are producing."
Excluding Alaska and Hawaii, Nevada is tied with the District of Columbia for the 11th highest average gas price in the country. The highest average price in the country is $3.52 in Alaska, a penny higher than Hawaii. California's average of $3.14 per gallon is the highest price in the lower 48 states.
