ABSTRACT
In the interim, i.e. the next twenty years, it seems that total energy content in a product will not be accurately reflected in its cost. This is partly because the total energy content of a raw material is not known or appreciated; partly because various energy sources are so vastly different in basic costs,4 and hidden by state subsidies, and partly because energy auditing as yet cannot fairly apportion the energy used on a works site to each product group. There is also considerable discrepancy amongst observers in the field as to whether process energy varies significantly with output or not. Evidence within the occupied capacity 5595% suggests that either connection may be valid.5,6
At a recent International Energy/Resources Conference in the United States of America, it was generally agreed that total selling prices of materials or products do not reflect their total energy contents.7
