Wood
Wood is a renewable resource. It has always been a traditional source of fuel. Considered a biofuel, timber is burned directly or converted into products such as wood ethanol or wood pellets.
The Pennsylvania State University School of Forests Resources states that 468 million tons of small diameter trees with original “low use” across the state can be harvested and used as an energy source. Researchers speculate that this unused timber could produce 480 to 600 million gallons of wood ethanol or produce twelve billion pounds of wood pellets, enough to heat 3 million homes each winter in Pennsylvania.
