Abstract
For the analysis of economic interdependences form an environmental perspective, a condensation of the information contained in input–output (IO) tables is desirable, but without much loss of the quantitative dimension. For the case of total energy requirements, main contributions identification is presented as an approach that allows a partitioning of total energy requirements by production layers and (final) energy-consuming sectors. For this purpose, a mixed monetary-energy IO model and a partitioning procedure are used. In addition, minimal flow analysis as a graphical method is used to detect importnant energetic interconnections. Environmentally Important Intersectoral Flows
