For American drivers filling up with premium at the gas station, AAA has a message for you: unless your owner's manual calls for premium, you're wasting your money.

Kentucky’s Energy and Environment Cabinet will hold three meetings across the state to take public comments on oil and gas development.


A conservative non-profit group says it doesn’t want state lawmakers to freeze the state’s plummeting gas tax.

With wages still stuck for many Americans, the big drop in gasoline prices is the equivalent of an unexpected cash bonus for the nation's drivers.

The average American household is expected to save $750 this year from lower gas prices, according to the Energy Department.

But Thomas Kinnaman, an economist at Bucknell University in Lewisburg, Pa., says it's instructive to look beyond the word "average."

Remember when we told you earlier this month that a gas station in Oklahoma City had lowered its price for regular unleaded to $1.99 a gallon?

Madisonville oil and gas production company Navitas Land and Mineral hopes to more than double its employees through a partnership with Chinese Company Shengli Highland Petroleum Equipment. Navitas CEO Daniel Williams says Highland will provide supplies and help with Navitas’s drilling site production.
