A Proponent's View
An Opponent's View � "Improve national security..." � Biomass will "worsen air pollution, � "Create jobs in rural � increase greenhouse gas America..." emissions, � "Provide energy at stable � deplete forests prices..." � and drain our public � "Reduce urban smog and coffers..." pollution that contributes to global warming..." � "for minimal amounts of power." � "Reduce oil from the Middle East..."

BIOENERGY

Increased harvest of residuals
� Impacts vary by:
� geography � forest type � utilization intensity

� Impacts a forests ability to:
� � � � support wildlife provide clean water sequester carbon regenerate understory spp

� Wood biomass policy should consider residuals.
