The potential of forest biomass as an energy supply for Canada

Abstract

There is a growing interest in using forest biomass as an energy source. The main objectives of this paper are to give somefigures and perspectives on Canadian forest biomass supply with respect to Canada’s energy demand and to examine thepotential of using this feedstock for reducing our greenhouse gas (GHG) emissions. Published estimates of forest biomasssupply as harvest residues are reported and discussed. The range of estimates listed here indicates that this source ofenergy is important but that it is still a fraction of our energy demands. The potential of using this biomass to reduce ourGHG emissions is strongly dependent, among other factors, on the technological pathways that are used, with direct heatproduction and combined heat and power (CHP) ranking amongst the best options available. The relative scarcity of theresource behooves us to use it efficiently. Key words: forest biomass, residue, greenhouse gas, mitigation, energy, sustainable forestry
