This paper presents the evaluation of a regional energy efficiency programme implemented in two "départements" of France. Électricité de France (EDF), a French energy company, provides refurbishment advice and financial incentives to end-users in the residential sector as well as specific training courses and certification to local installation contractors and building firms. Refurbishment measures analysed in this paper are efficient space heating equipment (condensing boilers, heat pumps and wood stoves or boilers), solar water heating systems and the installation of double-glazed windows. A billing analysis based on a survey of programme participants' energy consumption is used to calculate the energy savings attributed to the programme. In order to receive an economic feedback of this demonstration programme, the evaluation of both saved energy and programme costs is of importance. Detailed knowledge of the programme's cost-effectiveness is essential for EDF to achieve the saving obligations imposed by the French White Certificate scheme at the lowest cost. Results of this evaluation can support the development and implementation of further energy efficiency programmes with similar characteristics in other regions of France. The cost-effectiveness is determined from the perspective of the programme participant and the society as well as the energy company in charge of the programme. All cost and benefit components are calculated in Euro per kilowatt-hour, which allows a direct comparison of levelized costs of conserved energy with the avoidable costs of the energy supply system.
The core objective of Energy Efficiency Watch 3 (EEW3) is to establish a constant feedback loop on the implementation of European and national energy efficiency policies and thus enable both compliance monitoring and mutual learning on effective policy making across the EU. The project team applied a mixed-method approach to assess energy efficiency policy developments in EU Member States. EEW3 analysed the progress made in the implementation of energy efficiency policies in European Member States since the publication of the second National Energy Efficiency Action Plans (NEEAPs) in 2011 by screening official documents, sought experts' knowledge via an EU-wide survey and has been creating new consultation platforms with a wide spectrum of stakeholders including parliamentarians, regions, cities and business stakeholders. Results are presented in Country Reports for each of the 28 Member States, the Expert Survey Report, 10 Case Studies presenting outstanding energy efficiency policies in Europe, the Key Policy Conclusions, the project summary report in brochure format and this Feedback Loop Report, which summarises the overall EEW3 portfolio.
Energy efficiency improvements have numerous benefits/impacts additional to energy and greenhouse gas savings, as has been shown and analysed e.g. in the 2014 IEA Report on "Multiple Benefits of Energy Efficiency". This paper presents the Horizon 2020-project COMBI ("Calculating and Operationalising the Multiple Benefits of Energy Efficiency in Europe"), aiming at calculating the energy and non-energy impacts that a realisation of the EU energy efficiency potential would have in 2030. The project covers the most relevant technical energy efficiency improvement actions and estimates impacts of reduced air pollution (and its effects on human health, eco-systems/crops, buildings), improved social welfare (incl. disposable income, comfort, health, productivity), saved biotic and abiotic resources, and energy system, energy security, and the macroeconomy (employment, economic growth and public budget). This paper explains how the COMBI energy savings potential in the EU 2030 is being modelled and how multiple impacts are assessed. We outline main challenges with the quantification (choice of baseline scenario, additionality of savings and impacts, context dependency and distributional issues) as well as with the aggregation of impacts (e.g. interactions and overlaps) and how the project deals with them. As research is still ongoing, this paper only gives a first impression of the order of magnitude for additional multiple impacts of energy efficiency improvements may have in Europe, where this is available to date. The paper is intended to stimulate discussion and receive feedback from the academic community on quantification approaches followed by the project.
The core objective of Energy Efficiency Watch 3 (EEW3) is to establish a constant feedback loop on the implementation of European and national energy efficiency policies and thus enable both compliance monitoring and mutual learning on effective policy making across the EU. The project team applied a mixed-method approach to assess energy efficiency policy developments in EU Member States. It analysed progress of national policies by screening official documents, sought experts' knowledge via an EU-wide survey and has been creating new consultation platforms with a wide spectrum of stakeholders including parliamentarians, regions, cities and business stakeholders. Analysis of the National Energy Efficiency Action Plans (NEEAPs), the expert survey with input from over 1,100 experts on policy ambition and progress in each Member State, as well as 28 Country Reports have been central elements in EEW3. This paper will present the main conclusions and policy recommendations of EEW3. In doing so, it will first summarise the findings of the document analysis based on the 28 Country Reports, showing developments of energy efficiency policies since the second NEEAP in 2011 in a cross-country overview for six sectors. These findings are then contrasted with the experts' perspective on progress in energy efficiency policies in their countries as collected in the EEW survey. Moreover, ten case studies of good practice energy efficiency policies are shown, three of them will be presented in more detail. The paper ends with key policy conclusions for improving the effectiveness of European energy efficiency policies. A key finding is that policy implementation has improved a lot since 2011 but more is needed to achieve the EED Art. 7 and other targets.
The economic assessment of low-carbon energy options is the primary step towards the design of policy portfolios to foster the green energy economy. However, today these assessments often fall short of including important determinants of the overall cost-benefit balance of such options by not including indirect costs and benefits, even though these can be game-changing. This is often due to the lack of adequate methodologies.
The purpose of this paper is to provide a comprehensive account of the key methodological challenges to the assessment of the multiple impacts of energy options, and an initial menu of potential solutions to address these challenges.
The paper first provides evidence for the importance of the multiple impacts of energy actions in the assessment of low-carbon options.
The paper identifies a few key challenges to the evaluation of the co-impacts of low-carbon options and demonstrates that these are more complex for co-impacts than for the direct ones. Such challenges include several layers of additionality, high context dependency, and accounting for distributional effects.
The paper continues by identifying the key challenges to the aggregation of multiple impacts including the risks of overcounting while taking into account the multitude of interactions among the various co-impacts. The paper proposes an analytical framework that can help address these and frame a systematic assessment of the multiple impacts.
The European Horizon 2020-project COMBI ("Calculating and Operationalising the Multiple Benefits of Energy Efficiency in Europe") aims at estimating the energy and non-energy impacts that a realisation of the EU energy efficiency potential would have in the year 2030. The project goal is to cover the most important technical potentials identified for the EU27 by 2030 and to come up with consistent estimates for the most relevant impacts: air pollution (and its effects on human health, eco-systems/crops, buildings), social welfare (including disposable income, comfort, health and productivity), biotic and abiotic resources, the energy system and energy security and the macro economy (employment, economic growth and the public budget). This paper describes the overall project research design, envisaged methodologies, the most critical methodological challenges with such an ex-ante evaluation and with aggregating the multiple impacts. The project collects data for a set of 30 energy efficiency improvement actions grouped by energy services covering all sectors and EU countries. Based on this, multiple impacts will be quantified with separate methodological approaches, following methods used in the respective literature and developing them where necessary. The paper outlines the approaches taken by COMBI: socio-economic modelling for air pollution and social welfare, resource modelling for biotic/abiotic and economically unused resources, General Equilibrium modelling for long-run macroeconomic effects and other models for short-run effects, and the LEAP model for energy system modelling. Finally, impacts will be aggregated, where possible in monetary terms. Specific challenges of this step include double-counting issues, metrics, within and cross-country/regional variability of effects and context-specificity.
