Measurement of the Energy Intensity of Manufacturing Industries: A Principal Components Analysis
The authors apply principal components analysis to assess the information derived from six energy intensity indicators. They use two measures of total energy use (thermal and economic) and three measures of industry output (value added, value of production, and value of shipments). The data comes from manufacturing industries in Québec, Ontario, Alberta, and British Columbia from 1976 to 1996.
