This study analyzes changes in industrial aggregate electricity intensity, during the period 1998–2005, and identifies major factors affecting the aggregate electricity intensity change using the refined Laspeyers method decomposition technique. The Jordanian industrial sector was disaggregated into seven groups: mining of chemical and fertilizers, paper, plastics, petrochemical, cement, steel and others industries. Aggregate electricity intensity has decreased from approximately 1.30 to 0.93 kWh US$ −1 in 1998 and 2005, respectively. The analysis showed that the structural and efficiency effects contribute to decreases of around 21 and 79%, respectively, of total aggregate electricity intensity decline in the industrial sector. Such result is considered of high importance for energy and/or electricity analysts and planners, in Jordan and other countries, especially for the purpose of forecasting future demand more logically and without unnecessary exaggerations.
