Calculating the energy requirments of household purchases. A practical step by step method

Abstract

An accurate and fast method is presented for calculating the energy requirement of consumption items. The method combines process analysis and input-output analysis. The energy requirement of a particular consumption item is calculated in ten steps, each dealing with certain parts of the production network. Each step can be standardized to a large extent. The method is illustrated by applying it to one product: a domestic refrigerator.
