More than three dozen people took part in a conference on alternative energy sources in DeFuniak Springs.
The day-long event was sponsored by the Walton County extension office.
With the high cost of fossil fuels and America’s reliance on Middle East oil, the University of Florida is holding statewide meetings on alternative sources.
One of the demonstrations showed how peanut oil can be converted into a cleaner form of diesel fuel.
"Bio-diesel and ethanol price wise is now competitive with fossil fuels... and it's a lot more environment friendly. It doesn't give off as much carbon monoxide and carbon dioxide as fossil fuels," said Mike Goodchild of Walton Co. Extension Service.
There were also several demonstrations on the use of solar energy at the presentation.
