We need a fast
and accurate method for analysing the energy requirement of consumption patterns
that are inherent to many individual consumption categories. Here, we present
and discuss a hybrid method of input-output analysis and process analysis to
establish the energy requirement for the various consumption categories. This
hybrid method for energy analysis is suitable for rapidly and accurately
calculating the direct and indirect energy requirement associated with the
purchase and use of large numbers of consumption categories. The method detects
differences between consumption categories, even if they are produced by the
same economic sector. For individual products, of which the price level deviates
from the mean price, the use of input–output analysis for parts of the
calculations can cause errors. However, on average, the calculated energy
requirement will be correct. The error margins for individual products can be
reduced by using more process data, but more effort will be needed to make the
analysis.
