Overall project results and policy recommendations
Barbara Schlomann, Wolfgang Eichhammer (Fraunhofer ISI)
This report is submitted as deliverable 5.3 in the BRISKEE project with the aim of summarizing the overall project and policy recommendations derived from the three levels of analysis: the micro-level, meso-level and macro-level analysis that was conducted as part of work packages 2-4. The BRISKEE project has the objectives of providing evidence-based input to energy efficiency policymaking by investigating the role of household decision-making on three levels:
1) On the micro level, the project provides empirical evidence on the factors that influence investment decisions for energy efficiency technologies in households, in particular focusing on the role of household preferences for time discounting and risk, accounting for possible differences by technologies, household types, and countries.
2) On the meso level, the project explores the impact of time discounting and risk preferences, and the impact of policies affecting those factors on technology diffusion and energy demand in the residential sector in Europe up to 2030. The project uses inputs from the micro-level analysis in order to improve the representation of investment decisions in energy demand modelling tools.
3) On the macro level, BRISKEE explores the long-term macro-economic impacts of changes in microeconomic decision-making and of energy efficiency policy on employment, GDP and exports in the EU up to 2030.
The objective of this report is to summarize the overall findings and policy recommendations following from the micro-level analysis relying on the BRISKEE survey, the meso-level analysis based on the energy models FORECAST and INVERT/EE-Lab and the macro-level analysis based on the ASTRA macro-model.
Section 2 sets the starting point for the BRISKEE project, which is the debate about discount rates used in energy system modelling for EU target setting for energy efficiency. Section 3 develops the approach of the BRISKEE project to enlighten the debate on the discount rates, focused on the BRISKEE survey and the three levels of analysis: the micro-level analysis, the meso-level model-based analysis and the macro-level model-based analysis. Section 4 discusses the factors underlying implicit discount rates. Section 6 summarizes the approach taken in the BRISKEE survey. Sections 7 to 9 summarize the results and policy recommendations from the micro/meso and macro-level analyses. Section 10 presents overall conclusions and policy implications.
