Abstract

When an energy efficiency improvement occurs at the household level, several mechanisms, grouped under the name of the rebound effect, increase the available income and consumption, increasing the total energy consumption of the economic structure. The present research analyses the links between energy efficiency improvements in households, consumption, and the economic structure in an input-output framework. We examine, from an empirical perspective, the relationship between energy efficiency improvements and the economic structure, and between the direct and the indirect rebound effect. The limits of the input-output methodology in assessing the direct and indirect rebound effect have been empirically tested with respect to efficiency improvements of electricity uses in households in Catalonia.

6. Conclusions

The present research has analysed the indirect effects of an effi- ciency improvement in electricity use in households from a structural perspective using an input-output framework with Leontief production functions. This does not include the effects of the energy efficient improvement on productivity and economic growth or the effects of efficiency improvements on other agents or economic sectors. As stated in the introduction, the aim of this research was to understand the way in which the configuration of the economic structure can affect the energy savings derived from energy efficiency in households in a Leontief production framework. We found that, for low estimations of the direct rebound effect, the indirect rebound effect has a wider range of values that should be analysed depending on the economic context – which could lead from low to high rebounds. On the other hand, high estimates of the direct rebound effect yield less variability of the indirect rebound effect, converging to a direct and indirect rebound of 100%. To prove this, the hybrid model used in this research combines econometric, input-output, and re-spending models. Extreme cases reflect the potential direct plus indirect rebound of a Leontief production structure. However, they would be unlikely to occur at the aggregate level, although they could occur in a particular area at a microeconomic level.
