While it may seem there are as many advocates for green trucks as blades of grass, that’s not to say every fleet should switch from conventional fuels, according to John Flynn, CEO of Fleet Advantage, Fort Lauderdale, Fla., which provides equipment financing and lifecycle-cost management to large private fleets.

“Currently, there is no compelling reason to change to alternative fuels,” Flynn says. “Diesel is still the most efficient method of powering Class 8 vehicles available.” Still, he doesn’t entirely dismiss the value of going green. “Some companies may benefit from byproducts of the manufacturing of their product. A large agriculture or dairy operation may generate methane gas. If the production volume exists for the generation of methane and eventual processing into a fuel-delivery system, then that fuel could be used to power a fleet at a lower cost per diesel gallon equivalent.”
