So what does all this mean?

One Alternative is the Utilization of Woody Biomass as Fuel § We have an abundance of woody biomass that, in general, needs to be extracted for various reasons including: § § § Woody weed control, Integrated Pest Management, Fuel Load Reduction, Improving growth rates of standing timber, Salvage § But is NOT always extracted or utilized

What is Woody Biomass? § Woody biomass is the accumulated mass, above and below ground, of the wood, bark, and leaves of living and dead woody shrubs and trees.

What is Bioenergy? § Energy produced from biomass including woody biomass, agricultural biomass, and other biological materials § Includes electricity, heat, and transportation fuels

Availability of Biomass § OECD – commercial, industry-led § Asia and Latin America – modern, commercial § Africa – harvested informally Source: IEA 2003. Renewables Information. Paris

§ § Utilization of Biomass is the most important renewable energy source in the world today 10. 6% world total energy supply - 77. 4% total renewable energy supply § § Solid biomass has grown at 1. 8% Liquid biomass has grown at 84% Liquid Biomass 0. 7% Renewable Municipal Solid Waste 1. 20% Solid biomass/ charcoal 77. 4% Gas from Biomass 0. 50% Source: IEA 2003. Renewables Information. Paris

Biomass in the United States § Domestic energy production § 9% renewable: 47% biomass: 72% wood-based 2% Wind 45% Hydroelectric 5% Geothermal 47% Biomass 1% Solar Source: Energy Information Administration 2004

Energy Potential § Forest residues § Ethanol potential § Southern advantage Source: Mabee et al. 2006

Woody Bioenergy Potential • 40 million dry tons of recoverable logging residues in the US • Approximately 20 million dry tons in the South • Each Southern state could produce at least 100 MW of electricity using logging residues Capacity (MW) 300 or above(9) 200 to 299 (7) 100 to 199 (12) 50 to 99 (4) 0 to 49 (18) Operational power/electricity capacity from logging residues by state--Gan and Smith 2006
