u s wood energy potential
U.S. Wood Energy Potential
  • By 1980 USDA estimate, 600 million dry tons/year of “unused” wood
  • Using standard btu conversions, this is equivalent to 1.675 billion barrels of oil
  • US oil consumption is currently 7.3 billion barrels oil/year
  • Nearly one quarter of our oil consumption could be eliminated by full utilization of unused woody biomass
  • Carbon-neutral alternative to fossil fuels
definition
Definition
  • “LUW” – Low-use wood, defined by Luppold and Bumgardner (2003) as wood material that is underutilized, usually of poor form, size, quality, and value.
  • McWilliams and Frieswick (2007) – identify 57% of Pennsylvania’s 1.145 billion tons as LUW (658 million tons)
  • 71% of this (469 million tons) is available under PA operability constraints
  • Social constraints will reduce this availability more; how much = ?

Pennsylvania’s Forests – 16 million acres of biological “solar panels” storing carbon energy!

600 District Energy Projects

10 Wood Ethanol Plants

300 Million 40 lb bags of wood pellets

3 million homes

475 - 500 million gallons of #2 heating oil (Karakesh, 2007)

480-600 million gals ethanol

  • 658 million tons of our forest is in “under-utilized small diameter” stems; 469 million tons are potentially available for harvest
  • This volume of forest wood will sustainably yield about 6 million dry tons per year in perpetuity

6 Million Dry Tons Per Year is Equivalent to:

pressure on the resource
Pressure on the Resource?
  • 6 million dry tons annually – from growth only
  • “Energizing” forests could be utilized in efforts to accelerate mixed-aged “old-growth” forest structure and increase professional management options
key concepts for wood energy
Key Concepts for Wood Energy
  • On-site chipping or bundling
  • Transport minimization
  • Concentration and storage near processors
  • Harvest scheduling
  • Contractor recruitment and incentive
  • Site-specific sustainability criteria
  • Phytosanitary data and tactics
  • Community buy-in
  • Project-appropriate solutions
  • Ownership standards and agreements
  • Local industry database
  • Current and proposed project specifications
  • Data collection consolidation

  • Historical data and future projections
    • Species, size, and health of trees
    • Total tree growth, mortality, and removals
    • Wood production and utilization rates
    • Forest land ownership
  • Recently expanded to annual surveys and to include data on:
    • Soil
    • Understory vegetation
    • Tree crown conditions
    • Coarse woody debris
    • Lichen community composition
conclusion
Conclusion
  • There is a public groundswell for small and medium localized energy production
  • Sustainable harvest of available PA LUW will yield tremendous amounts of energy
  • In PA, we need resource utilization and biomass flow databases, state forest harvest plan requirements, and site-specific LUW harvest standards for proper planning, economic development, and landowner assistance
  • National greenhouse gas emission standards and federal biomass production incentives will make wood-based bioenergy happen – and move the U.S. closer to energy self-sufficiency
