On its quest to go green, the Frankfort Plant Board has converted its 55 diesel trucks and equipment to use biodiesel fuel.

"Biodiesel is better for the environment, decreases our dependence on foreign oil and contributes to the USA economy," said Herbbie Bannister, assistant general manager of the Plant Board. "Biodiesel is a clean-burning fuel manufactured from vegetable oils and animal fats. Soybeans are a main source.

It contains no petroleum, but can be mixed at any level with diesel to create a biodiesel blend. It is the only alternative fuel to have completed the health-effects testing requirements of the Clean Air Act and is registered as a fuel and fuel additive with the Environmental Protection Agency.

The decision to convert to biodiesel was fueled by positive feedback from auto manufacturers, fuel distributors and other utilities currently using biodiesel, Bannister said.

After a two-month test on three trucks, the Plant Board decided there were no negative impacts and made the switch.

Biodiesel and diesel are within fractions of a penny of each other so the switch has added no extra cost.

Bannister said the switch was definitely an easy one.

"We're using the same supplier," Bannister said. "We just changed the blend."
The Plant Board is also looking into other green options, Bannister said. A few Plant Board vehicles are testing an ethanol-blended, unleaded gasoline to check for negative impacts such as lower mileage. Also, a hybrid vehicle is scheduled to be purchased this year.

The Plant Board is also in discussion with state government to conduct a pilot test using LED streetlights. If approved, these streetlights could save 75 percent or more on energy usage compared with conventional street lighting.
This project is in its very early stages, Bannister said. The plant board is looking to find vendors that sell the wattages that would be needed.

"The LED lights are more expensive but will last longer," he said.

Andy McDonald, Kentucky Solar Partnership coordinator, wasn't aware the Plant Board was switching to biodiesel but said it will help raise awareness about alternative sources of energy.

"It's important for people to realize there are alternatives to petroleum and that we can produce them here in Kentucky," he said.

The Plant Board's decision to adopt biodiesel fuels could also encourage local governments and schools to make the same decision, he said.

"I think it sets a good example for the entire community," McDonald said.

Although biodiesel fuels are not yet available at local service stations, it might become widespread if demand for alternative fuels grows, McDonald said.
