Took a little Road trip today out to visit Down to Earth Energy in Monroe GA. about 20 miles from Athens. It is a solar powered, small batch, recycled grease bio-diesel facility, producing 3,300 gallons of B5, B20, B100 a day. They have three buildings aside from the rebuilt barn where they make the bio-diesel, each roof completely covered in solar panels. It is a 115kw system, which provides 80% of their power, and they are working on installing a diesel generator to run on bio-diesel to provide the rest.
Hard to see, but here's the pump: just drive up. B20 is $2.40 and B100 is $2.30 a gallon. They partner with Clean Energy Bio-Diesel, an Atlanta based company that picks up used grease and delivers finished bio-diesel. Their biggest customer is Whole Foods in Atlanta.
Solar hot water system is used to keep the finished bio-diesel hot, and for a variety of other work at the facility.
The bio-diesel is produced here in this re-built barn. This type of facility is the future: self sustaining, recycling, small batch production for regional delivery.
