The U.S. Department of Energy administers five Regional Bioenergy Programs to encourage regionally specific application of biomass and municipal waste-to-energy technologies to local needs, opportunities and potentials. The Pacific Northwest and Alaska region has taken up a number of applied research and technology projects, and supported and guided its five participating state energy programs. This report describes the Pacific Northwest and Alaska Regional Bioenergy Program, and related projects of the state energy agencies, and summarizes the results of technical studies. It also considers future efforts of this regional program to meet its challenging assignment.
