Die Entscheidung für ein von volatilen Erzeugungsquellen dominiertes Stromsystem stellt an die Stabilisierung des Systems neue Anforderungen. Zugleich bieten sich neue Optionen. Die bisherige Asymmetrie, nach der für die Stabilisierung die Kraftwerksseite verantwortlich sei, ist überkommene Praxis, deswegen auch heute habituell naheliegend, aber vermutlich nicht länger effizient. Die im Titel genannten nachfrageseitigen Ausgleichsoptionen (SE & DSM) bieten sich an. Im Beitrag wird deren Potential abgeschätzt. In vier Gestaltungsfeldern wird zudem gefragt, ob die bislang von der Politik gegebenen rechtlichen Mandate konsequent SE & DSM als Option berücksichtigen. Das Ergebnis ist viermal (weitgehende) Fehlanzeige.
What makes a good policy? : Guidance for assessing and implementing energy efficiency policies
(2013)
Which factors are crucial to successfully design and implement a "good practice" policy to increase the energy efficiency of buildings and appliances? This is one of the main challenges for the new web platform bigee.net that provides guidance on good practice policies.
In this paper we examine the question what "good practice" is by presenting a multi-criteria assessment scheme to analyse different policies worldwide.
The assessment scheme contains a set of criteria addressing key factors leading to the success of a policy as well as its outcomes: a good policy addresses all market players and barriers, avoids lost opportunities and lock-in effects, has ambitious and regularly updated energy efficiency levels, and spill-over effects. Other criteria are high energy savings and the calculated cost-effectiveness.
The assessment scheme provides a standardised data collection approach, which paves the way for both qualitative and quantitative evaluation. Furthermore, it can help policy-makers to transfer a successful policy.
The development of the scheme is based on a literature review of worldwide implemented policies and measures that promote energy-efficiency of buildings and appliances. Criteria were operationalized, including a ranking between 0 and 10. The ranking is a decisive factor whether the policy qualifies as good practice. To demonstrate the practicability of this scheme, the paper analyses a good practice example according to the assessment scheme: Energy-Efficient Refurbishment and Energy Efficient Construction programmes of the German public bank KfW.
This report analyses the international climate negotiations at the UN climate conference in Warsaw in November 2013. The report covers the discussions under the Durban Platform on developing a new comprehensive climate agreement by 2015 and increasing short-term ambition as well as the issues relating to near-term implementation of previous decisions in the areas of emission reductions and transparency, adaptation, loss and damage, finance and technology. The report concludes that Warsaw once again starkly highlighted the sharp divisions and lack of trust among countries. Industrialised countries' collective lack of leadership strongly contributed to re-opening the traditional North-South divide. As a result, on many issues the outcomes hardly go beyond the lowest common denominator. The conference only agreed on the bare minimum to move the 2015 process forward and also made no headway in strengthening short-term ambition. Some progress was made with the establishment of the "Warsaw international mechanism for loss and damage associated with climate change impacts" and the completion of the rules for reducing emissions from deforestation and forest degradation. However, here as well further substance, in particular financial support from industrialised countries, is required to actually fill these mechanisms with meaning. If countries want to escape from groundhog day, they will have to start seeing and utilizing the UN climate process rather differently.
Die Suche nach einem Ausweg aus den festgefahrenen Klima- verhandlungen ist derzeit eine der wichtigsten Aufgaben der internationalen Politik. Franz Josef Radermacher (2013) versucht, so einen Weg aus dem Politikstau aufzuzeigen: In verstärktem Ausmaß sollten Privatakteure eingebunden werden und Klimaschutzmaßnahmen finanzieren, weil die internationale Staatengemeinschaft bisher daran gescheitert sei, ein Folgeabkommen für das Kyoto-Protokoll abzuschließen. Von der Staatengemeinschaft verlangt Radermacher nur noch, überhaupt irgendein Abkommen zuwege zu bringen, das die globalen Emissionen zumindest einigermaßen deckelt. Weitere Emissionsreduktionen, die "Verhandlungslücke", sollen Unternehmen und Privatpersonen übernehmen, indem sie freiwillig Emissionszertifikate im Umfang von mehreren hundert Milliarden Tonnen CO2 kaufen und stilllegen. Darüber hinaus sollen weitere 150 Milliarden Tonnen CO2 über Aufforstungsprojekte aus der Atmosphäre herausgeholt werden (Sequestrierung).
Unfair und trickreich : wie Stromkonzerne mit großer Marktmacht Rekommunalisierungen behindern
(2013)
The transport sector is the second largest and one of the fastest growing energy end-use sectors, representing 24% of global energy-related greenhouse gas emissions. The International Energy Agency has developed scenarios for the transport sector within the overall concept of mitigation pathways that would be required to limit global warming to 2 °C. This paper builds on these scenarios and illustrates various passenger travel-related strategies for achieving a 2° transport scenario, in particular looking at how much technology improvement is needed in the light of different changes in travel and modal shares in OECD and non-OECD countries. It finds that an integrated approach using all feasible policy options is likely to deliver the required emission reductions at least cost, and that stronger travel-related measures result in significantly lower technological requirements.
The Durban Climate Conference agreed on the creation of a new market-based mechanism under the United Nations Framework Convention on Climate Change (UNFCCC) and to consider the establishment of an overall framework for various mitigation approaches, including opportunities for using markets ("Framework"). The creation of such a Framework is therefore of high political significance, as it should ensure on the one hand that new market-based mechanisms contribute to global climate change mitigation and to achievement of targets, and on the other hand, that different market-based approaches can be integrated in a global carbon market. As yet, there is little clarity as to the roles and design of such a framework. This paper contributes to the debate by discussing and evaluating inter alia several design options, and explores how the various options could be implemented and how they interrelate. It concludes that a strong central oversight at the level of the UNFCCC is probably the only option that could reassure the vast majority of UNFCCC Parties that the environmental integrity of new market-based mechanisms is in fact ensured. This does, however, not exclude that some reasonable balance may be struck between centralization and flexibility.

There's no decarbonisation without energy efficiency : but take care of the "rebound effects"
(2013)
The European electricity market is linked to a carbon market with a fixed cap that limits greenhouse gas emissions. At the same time, a number of energy efficiency policy instruments in the EU aim at reducing the electricity consumption. This article explores the interactions between the EU's carbon market on the one hand and instruments specifically targeted towards energy end-use efficiency on the other hand. Our theoretical analysis shows how electricity demand reduction triggered by energy efficiency policy instruments affects the emission trading scheme. Without adjustments of the fixed cap, decreasing electricity demand (relative to business-as-usual) reduces the carbon price without reducing total emissions. With lower carbon prices, costly low emission processes will be substituted by cheaper high emitting processes. Possible electricity and carbon price effects of electricity demand reduction scenarios under various carbon caps are quantified with a long-term electricity market simulation model. The results show that electricity efficiency policies allow for a significant reduction of the carbon cap. Compared to the 2005 emission level, 30% emission reductions can be achieved by 2020 within the emission trading scheme with similar or even lower costs for the industrial sector than were expected when the cap was initially set for a 21% emission reduction.
Strategic policy packages to deliver energy efficiency in buildings : their international evidence
(2013)
The project "bigEE - Bridging the Information Gap on Energy Efficiency in Buildings" presents comprehensive information for energy efficiency in buildings and the related policy on the international internet-based knowledge platform bigee.net.
To develop the evidence-based information required for bigee.net, we addressed in a different and more systematic way than usual the question of how policy can support improved building energy efficiency most effectively: We combined (1) a theoretical, actor-centred analysis of market-inherent barriers and incentives for all actors in the supply and use chain of (energy-efficient) buildings to derive a recommended package combining the types of policies and measures the actors need to overcome all these barriers, with (2) empirical evidence on model examples of good practice policy packages to check if advanced countries have indeed used the combination of policies we derived from the actor-centred analysis.
In this way, we found that the recommendable policy package for new buildings is similar to the well-known one for appliances, but with the objective to mainstream nearly zero energy buildings. By contrast, the task for existing buildings is two-dimensional - increasing the depth of renovation first, to savings of 50 to 80%, and then the rate of energy-efficient renovation to 2% or more p.a. - and so the policy package needs more emphasis on individual advice, incentives, and financing. The paper presents the recommended packages as well as a comparison of existing national policy packages from California (USA), China, Denmark, Germany, and Tunisia and what we learned from it for effective packages and implementation.

Shifting baselines : the interdependency of local and national policies to reduce GHG emissions
(2013)
Climate change and thus low-carbon transitions are global challenges, which require commitment and effort on all political levels. As international climate politics has approached its limits over the last two decades, the role of cities has simultaneously gained in importance. Many cities1 worldwide have committed to ambitious climate protection targets, which often exceed national targets. However, cities cannot act in isolation. Their opportunities for action are embedded in an (inter)national policy framework, which may either support or hinder local actions. This gives rise to the question: which opportunities for climate protection do cities really have in a political system of multi-level governance?
This question can be illustrated using the city of Hamburg as an example for the German climate policy regime. The city aims to reduce its annual CO2 emissions by 2 million metric tons and attempts to quantify the impact of local and national policies and actions using a bottom-up monitoring approach. We therefore analyse more than 400 local actions with respect to the induced CO2 emission reductions. We also take a closer look at national and European policies and their impacts on local energy use and emissions. In total, 15 policies and instruments - broadly ranging from instruments to foster energy efficiencyin residential and non-residential buildings, in appliances and in the transport sector, to support renewable energy sources (including biofuels) and to uptake CHP - are considered.
Our approach consists in measuring separately the impact of local and national policies and actions on urban CO2 emissions. While the city of Hamburg has implemented many policies and actions, our results show that, a significant proportion of its CO2 reduction is due to national policies, in the context of the German "Energiewende", which cannot or can only indirectly be influenced by the city. The results imply that local commitment and effort is essential in addressing the global challenge, yet ambitious targets can only be met in the presence of a supportive national policy framework. The analysis shows that many policies and measures implemented at national level require supportive structures and activities at local level in order to bridge information and implementation gaps of these measures.
Sei clever! : Spare Energie
(2013)
The role of cities in mitigating GHG emissions and thus tackling global warming has gained importance over the last years.Many cities have developed climate action plans, primarily to achieve long-term "low-carbon" mitigation goals set by national governments or (inter)national agreements. A mere adoption of high level targets, however, raises the question whether these targets are applicable for cities with very different framework conditions.
We argue that it is crucial to understand the socio-economic, geophysical, spatial, infrastructural and political framework of a city - a broad approach, which is generally missing in climate action plans. Thus, determining drivers and barriers for future development paths is neglected by local policies, which leads to a gap between ambition (target) and reality (implementation).
We exemplarily examine this hypothesis for the shrinking city of Oberhausen (Germany). Oberhausen, located in the Ruhr area,is a typical old industrial region, which has seen a decline of its industrial basis over the last decades. We analysed historical data and developed scenarios until 2030. Both show a significant decrease in CO2 emissions. A closer look, however, reveals that the reduction is primarily due to the economic transformation (less manufacturing, more service industry, accompanied by a decrease in population) and general energy efficiency developments following the implementation of national and EU policies. Although the city has implemented–and will further implement - many instruments and policies to reduce CO2 emissions, local barriers such as unemployment, low rents, low income, high per capita debts, etc. dramatically reduce the city's capacity for action.
The results show that Oberhausen's emission reductions do not reflect active energy policies but are mainly driven by an economic decline. To reach ambitious reduction targets, however, the city needs to be enabled to take action in achieving appropriate and reasonable targets.
Many European city governments have voluntarily committed to ambitious CO2-emission reduction targets until 2020 and 2050. Supported by dedicated structures and networks (e.g. Covenant of Mayors), local governments have already developed, or are currently developing, ambitious climate action plans, all pursuing the aim of radical CO2-emission reduction in the long term.
Though, the development of climate action plans is only a first step, as the actual crucial and more challenging part its implementation. Besides financial investments also additional capacities, improved institutional structures and innovative strategies are necessary to successfully implement ambitious policies within existing national and regional framework conditions. There is often more competition than co-operation between cities. However, exchanging on common challenges in order to find new solutions provides potential for innovative ideas and new views on own structures. In particular, methods and formats for self-assessment and mutual learning can support cities' stakeholders to overcome their implementation gap in local energy and climate policies.
This paper will present results from the first phase of the three year project "CASCADE", which was initiated by 19 European cities in co-operation with EUROCITIES. Within the project, implementation challenges are being addressed in an intensive process of self-assessment and mutual learning. The methodological "backbone" of this process is a qualitative benchmarking framework in the thematic fields of "Renewable energy sources and distributed energy generation", "Energy efficient buildings and districts" and “Energy in urban transport”. Up to a certain degree, existing local climate policy benchmarks provide a common exchange platform, but mainly for the comparison between cities. The CASCADE benchmarking framework goes beyond competitive comparisons. As a qualitative criteria-based assessment procedure it identifies key challenges and factors for a successful implementation of established local climate policy plans. These factors have been developed from a qualitative survey including interviews and workshops with representatives of the participating cities.
Six cities serve as examples. Self-assessment reports were provided based on the CASCADE benchmarking framework focussing on the implementation status of their local climate policies. These reports were reevaluated by four or five project partners from different cities in a desk-review process. During subsequent four-days peer learning visits, the CASCADE benchmarking framework was used again as a tool for an in-depth assessment of the local climate and energy action plans and the local activities towards implementation of these strategic documents. Finally, the visitors drafted a feedback report with recommendations and improvements for the hosts.
The paper describes the methodology of the CASCADE benchmarking framework for integrated learning, its applicability for peer learning processes, as well as first experiences and results from the peer learning visits.
In recent years, policies to promote renewable energy have become increasingly popular among municipalities in different parts of the world. This article examines the case of Germany. It argues that municipalities, compared to other state and private actors, already have the potential to play a key role in German renewable energy governance. Although both private actors and the European Union have gained importance in the past 20 years, German municipalities still play a crucial role and can apply five distinct and important modes of governance in the field of renewable energy policy. In this regard, the notion of a general development towards a "cooperating and ensuring state", which increasingly delegates its tasks and thus becomes less important, cannot be confirmed in the field of municipal renewable energy governance in Germany.
