In 1994, the lumber and wood products sector generated 341 trillion Btu, or 69% of the industry’s energy needs, from wood residues. Remaining energy needs were met by electricity, natural gas, and fuel oil. Of the 1,373 trillion Btu self-generated by the pulp and paper industry, approximately 64% was provided by black liquor from pulping operations, with 30% provided by wood residues. The pulp and paper industry is a large electricity consumer; since many newer processes are electricity-intensive, the sector will likely increase its use of electricity as production increases. The industry also uses large amounts of fuel oil relative to other industries. [MECS 1994]
