DEA sensitivity analysis on the factors responsible for industrial energy consumption: Case study on the Canadian industrial sector

Energy consumption efficiency is a function of several input variables governing the consumption patterns or behavior. The degree to which efficiency responds to these variables and/or combination thereof will give insight into strategies or ways to better manage energy consumption within an industry. This paper endeavors to evaluate the operation of Canadian industrial sector between year 1990 to 2000, based on data from 15 Canadian industries using Data Envelopment Analysis (DEA). The overall operation is analyzed, and sensitivity analysis is used to appraise the role/relevance of various input factors and their combination thereof.
