Total energy consumption by the Quebec manufacturing sector increased by 18,8 % from 1990 to 1998. The decomposition of this increase by factors allows us to identify the roles played by the added value of total manufacturing sector (14,9 %), the change of its structure (6,2 %) and the change of energy efficiency (-2,4 %). This shows the difference between gross energy intensity, which is measured directly from available data for the total manufacturing sector, and net energy intensity, which takes into account the changes of the shares of economic activity originating from each industry. The latter is used as an indicator of the evolution of energy efficiency. La consommation totale d’énergie du secteur manufacturier québécois a augmenté de 18,8 % entre 1990 et 1998. La décomposition factorielle de cet accroissement permet d’identifier les rôles joués par l’activité économique mesurée par la valeur ajoutée (14,9 %), son changement structurel (6,2 %) et le changement de l’efficacité énergétique (-2,4 %). Elle met en lumière la différence entre l’intensité énergétique brute mesurée directement à partir des données observées pour le secteur manufacturier total et l’intensité énergétique nette qui prend en compte les changements de parts d’activité des industries manufacturières. C’est l’intensité énergétique nette qui est utilisée pour mesurer l’évolution de l’efficacité énergétique.
