摘要：

An input-output study of the energy requirements for the manufacture of basic iron and steel products by the Australian steel industry is presented. The basis of this study is a decomposition of the total energy requirement per mass output of steel into partial requirements from industry sectors supplying the steel industry. A separation into different order requirements shows that lower order energy requirements for basic iron and steel, chosen from the supplying industries identified in a recent process analysis, are 19 MJ/kg, and that the total energy requirement is 40.1 MJ/kg, This proportion demonstrates that truncation error in this process analysis, that is, the omission of higher order energy contributions, is of the order of 50%.
