Abstract

Energy consumption of the iron and steel industry during the period 1980-1991 was studied in seven countries (Brazil, China, France, Germany, Japan, Poland and the USA). To understand trends in Poland, we compare developments there with those of the countries over time. Using a decomposition analysis based on physical indicators we decompose the changes in intra-sectoral structural changes and efficiency improvements. Energy intensity decreased in all countries, except Poland. Efficiency improvement played a major role in Brazil, China, Germany and the USA, while structural changes seem to be the major driver for energy savings in France and Japan. The methodology also makes it possible to estimate the potential for energy efficiency improvement relative to a ?est-practiceƒ reference plant. In Poland the potentials (in 1991) was 43%, compared to a low of 9% for Germany, and a high of 63% for China. Finally, based on an understanding of past energy efficiency developments we discuss opportunities and measures for the iron and steel industry.
