The Mississippi Natural Gas Association and natural gas dealers in this area say the state could save big by converting its 24-hundred vehicle fleet to natural gas power.
Natural gas is about half the cost of gasoline, and some places more than half. The problem is it takes a big tank to hold it and it is not available everywhere.
Fifty-four-year-old Mark McConville is originally from Birmingham, but he has just completed a cross country trip in a natural gas-powered 1966 Pontiac GTO, from Santa Monica, California to Chicago, Illinois.
"I wanted to highlight that America has a great energy source, which is compressed natural gas. A lot of it," said McConville. "In an American car we should be able to highlight it, this whole need for an energy source that's domestic."
There have been efforts for years to get the state to convert to natural gas, to power many of it's vehicles, but it seems to never happen.
"I just believe that the average person doesn't have the information about how right this really is." said Mississippi Natural Gas Association Executive Director Cherrell Grogan.
Mike Horton of the Northeast Mississippi Natural Gas District says the education community could really save by powering school buses with natural gas.
"We are paying $4.00 a gallon for diesel on a school bus," said Horton. "We could be buying natural gas for $2."
Mark McConville let me drive his natural gas-powered Pontiac GTO. I didn't find it much different from a gasoline powered car.
