What role will forests play in America's long-term energy future? (Special Issue: Sustainable wood bioenergy in the United States.)

摘要

Wood biomass is expected to fulfill multiple renewable energy objectives as a flexible feedstock for the production of liquid transportation fuels, renewable electricity, and thermal energy. This article analyzes the projected demand for biomass associated with federal mandates for renewable electricity and transportation fuels. The analysis finds that the combined demand for the biomass needed to produce liquid biofuels and electricity could result in more than a twofold increase in volume of wood harvested annually in the United States. Several recommendations are offered for maximizing the potential for woody biomass to contribute to renewable energy and climate change mitigation goals.
