Abstract in Undetermined

Economic development that includes investments in infrastructure and buildings requires energy intensive basic materials such as steel and cement. The production capacity of these industries is also growing most rapidly in developing countries [WEC, 1995 #41]. Energy intensive industries typically account for a relatively small share of the value-added in industry but a relatively large share of industrial energy use and associated carbon-dioxide emissions. They are therefore likely to be the target of national and international efforts to reduce emissions, for example through mechanisms as devised in the protocols to the climate convention.



The overall objective of this project is to improve our understanding of industrial energy use and efficiency in developing countries and in particular explore explanatory factors for success and failure in reaching high levels of efficiency. Large differences can be found when comparing industrial energy efficiency for specific industry branches across countries. Such comparisons may be misleading if differences in energy statistics and industrial product mix, quality or input materials are not accounted for. The work presented here is in part a contribution to the development of methodologies for international comparisons and an input to the International Network for Energy Demand Analysis hosted by the Energy Analysis Department at the Environmental Energy Technologies Division of the Lawrence Berkeley National Laboratory (LBNL).



The first phase of the project which is reported on here focus on the cement industry and methodologies for international comparisons of energy efficiency in the cement industry. The cement industry was selected in part because it produces relatively homogeneous products, clinker and cement, albeit of various qualities, which should facilitate international comparisons. The analysis of different methods is primarily based on data for eight selected countries in the database hosted by LBNL.



The results presented here serves as a background and starting point for more in-depth assessments of underlying factors for success and failure in energy efficiency in the cement industry. An analytical framework for systematically assessing relevant factors is proposed. In the next project phase, China has been selected as a case-study country due to its rapid growth in cement production, an interesting mix of small cement kilns in township and village enterprises and large modern cement plants, and its apparently high level of energy efficiency in large parts of the industry.
