2.4.4. General resultsIt is difficult to predict exactly what quantities of biomass resources will be available at whatprice for a specific location. However, the least-cost biomass resources needed to provide 10.65TBtu/year (enough to generate three 40 MW facilities) in scenarios #2 and #3 would becomprised of about 35% urban wood waste, 42% logging residues, and about 20% fromthinnings of natural stands and plantations. About 3% of this least-cost supply of 10.65TBtu/year would be met with nearby pulpwood (Figure 18). The quantities of resourcesincluded in these scenarios are about 100%, 28%, 27%, 25%, 15%, and 0.4% of annuallyavailable urban wood waste, logging resides, thinnings from longleaf pine restoration, thinningsfrom overstocked plantations, thinnings from overstocked natural stands, and pulpwood,respectively, within the two-hour one-way woodsheds, excluding overlap of adjacent woodsheds(Figure 19).OverstockedNatural Stands,0.16, 1% Pulpwood, 0.32,3%OverstockedPlantations,0.69, 6%LongleafRestoration,1.38, 13%Urban Wood,3.76, 35%LoggingResidues, 4.34,42%Figure 18.
