equipment is gasoline-fueled. Energy requirements for biomass hauling are estimated for a truck, with a fuel economy of 5 mpg, hauling 37,000 lb of biomass over a 50-mile round trip. The energy requirements per unit of product fuel are based on the process yield considerations in Section 4.2.

The California Energy Commission (CEC) and DOE have explored numerous approaches for producing biomass feedstocks. Two studies included estimates of energy inputs for wood based feedstock in California.
