With the price of gas and diesel fuel at a premium, the county is moving toward more fuel-efficient vehicles for the sheriff’s department, according to County Executive John Pelham.Pelham says several departments will exceed their fuel allotments in the budget this year due to the dramatic rise in fuel prices.“Everybody’s looking for ways to be more conservative if we can, to be smarter with the county’s money,” Pelham said. “The commissioners are always looking at that. With what fuel we’ve used this past year, obviously with fuel prices what they are, we’ve probably had overruns in all of our departments.“We certainly have gone over in the sheriff’s department and the ambulance service, so our fuel expenses have been a major topic of conversation,” Pelham continued.
