Im Herbst 2001 veröffentlichte Bundeswirtschaftsminister Werner Müller einen viel diskutierten Energiebericht. Neben einer Bestandsaufnahme der deutschen Energie- und Klimapolitik befasst er sich auch mit einer Analyse der zukünftigen Entwicklungsmöglichkeiten des Energiesystems. Dabei steht die Frage im Vordergrund, ob und wenn ja, zu welchem Preis eine über das bisher von der Bundesregierung beschlossene Maß hinausgehende Minderung der CO2-Emissionen möglich ist. Referenzpunkt ist das Ziel, im Jahr 2020 eine CO2-Reduktion von 40 Prozent gegenüber dem Niveau des Jahres 1990 zu erreichen. In seinen Zukunftsaussagen basiert der Energiebericht im Wesentlichen auf einer Untersuchung von Prognos/EWI/Bremer Energieinstitut aus dem Frühjahr 2001. Der Energiebericht will mit dieser Zukunftsbetrachtung einen Beitrag zum energiepolitischen Diskurs leisten und eine intensive Diskussion entfachen. Das Wuppertal Institut stellt sich dieser Aufforderung mit vorliegender Antwort. Dabei sollen die Aussagen und Schlussfolgerungen des Energieberichts kritisch hinterfragt und eigenen Überlegungen gegenübergestellt werden.

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.
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.
Transformative Innovationen : die Suche nach den wichtigsten Hebeln der Großen Transformation
(2021)
Der hier vorliegende Zukunftsimpuls soll den Grundgedanken der Transformativen Innovationen und ihre Notwendigkeit beschreiben sowie erste Kandidaten für solche Transformativen Innovationen aus diversen Arbeitsbereichen des Wuppertal Instituts vorstellen. Er dient vor allem als Einladung, gemeinsam mit dem Wuppertal Institut über solche Innovationen zu diskutieren, die irgendwo zwischen den großen Utopien und kleinen Nischenaktivitäten liegen. Denn es braucht nicht immer den ganz großen Wurf, um Veränderungen in Gang zu setzen.

Toothless tiger? : Is the EU action plan on energy efficiency sufficient to reach its target?
(2007)
Motivated by, inter alia, the increasing energy prices, the security of energy supply and climate change, the new EU "Action Plan for Energy Efficiency: Realising the Potential" (EEAP), sets out the policies and measures required to be implemented over the next six years to achieve the EU's goal of reducing annual primary energy consumption by about 20 % by 2020. By increasing energy efficiency, the security of energy supply and the reduction of carbon emissions are also improved.
The paper will analyse the 20 % target of the new EEAP for the energy demand side by comparison with different recent energy scenarios for the EU. It will therefore review the recommended policies and measures and examine, in which energy demand sectors energy efficiency may be increased and to which extend. The main focus is whether the recommended policies and actions will be sufficient and which additional measures may be useful, if additional measures are needed.
Based on a comprehensive scenario analysis of the EU's GHG emissions by 2020, we show that the 20% energy savings target set in the Action Plan "Doing more with less" in 2006 is still the most significant and thus indispensable strategy element within an ambitious EU climate and energy strategy targeting at a 30% reduction of GHG emissions by 2020.
The scenario analysis provides a sector by sector projection of potential future energy use and GHG emissions, combined with a detailed policy analysis of the core policies on energy efficiency by the EU and its Member States taken from current research results by the authors and others.
Consequently the paper identifies and quantifies the current implementation deficit in the EU and shows that, despite of sufficient targets, implementation is still significantly lacking in almost all fields of energy efficiency. Some, e.g. transport sector and buildings, are still substantially far from receiving the necessary political impetus. The paper also demonstrates co-benefits of a strong energy efficiency strategy, e.g. the achievability of the targets of the RES directive, which crucially depends on a strong efficiency policy.
We conclude that the efforts of the energy efficiency policy of the EU and its Member States have to be significantly intensfied. As proposed by the EU in case that other developed and key developing countries take up comparable targets in order to fulfil its role in the climate and energy strategy. To achieve this, we offer an analysis of the current weaknesses of EU energy efficiency policy and derive recommendations on how the EU can still reach its targets for 2020.
Target 2020 : policies and measures to reduce greenhouse gas emissions in the EU ; final report
(2005)
The German climate change programme (2000) identified the residential sector as one of the main sectors in which to achieve additional GHG reductions. Our case study compiles results of existing evaluations of the key policies and measures that were planned and introduced and carries out some own estimates of achievements. We show, which emission reductions and which instruments where planned and what was delivered until 2004.
Legal instruments such as the revised building code were introduced later than planned and their effects will - at least partly - fall behind expectations. Other legal instruments such as minimum energy performance standards for domestic appliances etc. were - in spite of the programme - not implemented yet.
On the other hand, substantial financial incentives were introduced. Especially schemes granting low-interest loans for building renovation were introduced. However tax subsidies for low-energy buildings were phased out.
In general we can conclude from our case study that Germany was not able to compensate for the slower or restricted implementation of legal instruments through the introduction of financial incentives. Particularly the efficient use of electricity has been left aside as almost no further policy action was taken since 2001.
Thus energy efficiency in the residential sector will not deliver the GHG reductions planned for in the German climate change programme until 2005. From our findings we draw conclusions and recommendations towards policy makers: Which lessons are to be learnt and what has to be done in order to fully harness EE potentials in residential sector as planned for 2010?
Die vorliegende Studie im Auftrag des Ministeriums für Klimaschutz, Umwelt, Landwirtschaft, Natur- und Verbraucherschutz des Landes NRW liefert zunächst in Kapitel 2 einen Überblick über wichtige grundsätzliche Zusammenhänge, die für eine Diskussion der Strompreiseffekte eines beschleunigten Ausstiegs zu berücksichtigen sind und stellt etwaige Preiswirkungen in den größeren Zusammenhang weiterer, ggf. auch positiver ökonomischer Wirkungen einer beschleunigten Energiewende. In Kapitel 3 werden anschließend die bisher öffentlich verfügbaren Untersuchungen und wissenschaftlichen Stellungnahmen zu der Frage der zu erwartenden Strompreiseffekte einzeln vorgestellt und bewertet. Das Fazit in Kapitel 4 fasst schließlich den aus den verschiedenen Studien und Stellungnahmen abgeleiteten aktuellen Wissensstand zur Untersuchungsfrage zusammen und geht kurz auf mögliche politische Maßnahmen zur Begrenzung der Strompreiseffekte sowie der damit potenziell verbundenen negativen Auswirkungen ein.
There's no decarbonisation without energy efficiency : but take care of the "rebound effects"
(2013)
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 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.
Improvements in energy efficiency have numerous impacts additional to energy and greenhouse gas savings. This paper presents key findings and policy recommendations of the COMBI project ("Calculating and Operationalising the Multiple Benefits of Energy Efficiency in Europe").
This project aimed at quantifying the energy and non-energy impacts that a realisation of the EU energy efficiency potential would have in 2030. It covered the most relevant technical energy efficiency improvement actions in buildings, transport and industry.
Quantified impacts include reduced air pollution (and its effects on human health, eco-systems), improved social welfare (health, productivity), saved biotic and abiotic resources, effects on the energy system and energy security, and the economy (employment, GDP, public budgets and energy/EU-ETS prices). The paper shows that a more ambitious energy efficiency policy in Europe would lead to substantial impacts: overall, in 2030 alone, monetized multiple impacts (MI) would amount to 61 bn Euros per year in 2030, i.e. corresponding to approx. 50% of energy cost savings (131 bn Euros).
Consequently, the conservative CBA approach of COMBI yields that including MI quantifications to energy efficiency impact assessments would increase the benefit side by at least 50-70%. As this analysis excludes numerous impacts that could either not be quantified or monetized or where any double-counting potential exists, actual benefits may be much larger.
Based on these findings, the paper formulates several recommendations for EU policy making:
(1) the inclusion of MI into the assessment of policy instruments and scenarios,
(2) the need of reliable MI quantifications for policy design and target setting,
(3) the use of MI for encouraging inter-departmental and cross-sectoral cooperation in policy making to pursue common goals, and
(4) the importance of MI evaluations for their communication and promotion to decision-makers, stakeholders, investors and the general public.
The implementation of energy efficiency improvement actions not only yields energy and greenhouse gas emission savings, but also leads to other multiple impacts such as air pollution reductions and subsequent health and eco-system effects, resource impacts, economic effects on labour markets, aggregate demand and energy prices or on energy security. While many of these impacts have been studied in previous research, this work quantifies them in one consistent framework based on a common underlying bottom-up funded energy efficiency scenario across the EU. These scenario data are used to quantify multiple impacts by energy efficiency improvement action and for all EU28 member states using existing approaches and partially further developing methodologies. Where possible, impacts are integrated into cost-benefit analyses. We find that with a conservative estimate, multiple impacts sum up to a size of at least 50% of energy cost savings, with substantial impacts coming from e.g., air pollution, energy poverty reduction and economic impacts.
On 26 January 2019, the Commission on Growth, Structural Change and Employment recommended that no more coal-fired power plants would be operated in Germany by 2038 at the latest. In this paper the Wuppertal Institute comments on the results of the Commission and makes recommendations for the current necessary steps for the climate and innovation policy in Europe, Germany and North Rhine-Westphalia.
