Gas Bottoms Out

The national average for a gallon of gas — $1.883 as of Friday, according to the latest data from AAA — is the cheapest it's been in more than four years. In just the last month, the national average per gallon has dropped 48 cents, and current prices are 32 percent below what you paid a year ago.

Here in Tennessee, the average price of a gallon of gas currently sits at $1.77. That's 45 cents less than one month ago and nearly 71 cents less than one year ago. A BP station in London, Kentucky, just north of Knoxville, is apparently the first in the nation to drop its gas prices to 99 cents per gallon.

Relatedly, demand for gas is at its lowest level since 1968, according to  Oil Price Information Services. Data from the Energy Information Administration shows that for the week ending April 3, gas usage had fallen 48 percent year-over-year, to 5.065 million barrels per day.
