Multilevel decomposition of industrial energy consumption

Abstract

This study deals with the decomposition of industrial energy consumption at two levels of sector disaggregation or more. Past studies are reviewed and the need for multilevel decomposition is examined. Simple procedures for multilevel decomposition are presented. The proposed procedures, which are extensions of often used single-level decomposition procedures, allow estimates of various effects at different disaggregation levels to be made and interpreted in a consistent manner. Application studies using the data of Singapore industry are presented. Several application issues pertinent to multilevel decomposition are also discussed. © 1995.
