The Tennessee gas price average continues to climb. It is now $2.68 which is 40 cents more than one month ago and 63 cents more than one year ago. Following last month’s winter storm in Texas, the national gas price average has jumped nearly 40 cents to $2.86. Officials say prices will continue to increase this week, especially following the Energy Information Administration’s latest weekly reports showing a second week of major decline in gasoline stocks and a substantial increase in U.S. demand.
