Energy labelling for household appliances has become an established instrument to promote energy efficiency. For heating systems, however, this approach has not been successfully implemented yet. This is partially due to the reluctance of industry.
To find ways to motivate industry to participate in a labelling scheme, we carried out a survey among producers of heating systems. Respondents to our questionnaire and personal interviews cover together more than 30 percent of the EU market for heating systems. Thus the results provide a solid basis for conclusions.
Our survey helps to draw a much better picture of the attitudes and expectations of the manufacturers with regard to a labelling scheme. The paper covers:
Attitudes regarding potential effects of a label; Opinions on possible design of a label; Perceived effects of the labels for the companies; Perceived advantages and disadvantages of a label; And, as a conclusion, the potential effects on the companies and their probable relevance.
As a result, industry representatives expect that customers will be able to make sounder purchasing decisions because of the availability of a label. Therefore they believe that energy savings will be achieved. What is more, respondents expect that a label could improve integration of the European market for heating systems and would rather improve their individual economic performance.
The survey results in a clearer identification of industry's problems, needs and interests. It thus will help policy-makers to get industry to support energy efficiency labels and activities.
Although the anticipated "end of cheap oil" has boosted the interest in energy efficiency as a cornerstone of energy and climate strategies, it is usually taken into account on the basis of rather narrowly defined cost-benefit considerations. As a consequence, substantial ancillary benefits are usually barely considered.
In a recent study for the European Parliament (EP), the authors assessed two enhanced climate strategies compared to a more conventional strategy. One enhanced climate policy scenario relies, in particular, on raising the annual pace of energy efficiency improvement. The other aims at a radical boost of the market share of renewable energy forms, which, however, presupposes an equally radical improvement of energy efficiency.
The present article presents the scenario results and places them in the context of risk characterisation of the considered climate policy scenarios. Risks of international turmoil and energy price hikes could be reduced if dependency rates for fossil fuel imports went down. A more ambitious climate policy can also strengthen the EU position in post-Kyoto global climate agreements and a moderated need for emission trading can, for example, reduce conflicting pressures on clean technology transfer.
On the other hand, the implementation of the efficiency strategy will entail increased domestic risks because it will involve a re-prioritisation of resource allocation and will thus affect the current distribution of wealth in both the energy sector and some other closely related sectors.
The article outlines the main drivers behind the ambitious energy efficiency scenario and it attaches tentative price tags to the ancillary effects, with special emphasis on the above sketched swapping of risks. It will, therefore, strongly argue for a more holistic view, which underscores the need for political action and the benefits of such proactive policies in favour of energy efficiency.
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.
Iran is one of the largest oil producers and natural gas owners globally. However, it has to struggle with domestic energy shortages, economic losses through energy subsidisation and inefficient energy infrastructures. Furthermore, GHG and other energy related emissions are rapidly increasing and posing a growing threat to local environment as well as global climate. With current trends prevailing, Iran may even become a net energy importer over the next decades. Resource allocation is therefore a crucial challenge for Iran: domestic consumption stands versus exports of energy.
The energy transformation sector clarifies Iran's dilemma: soaring electricity demand leads to blackouts, and power plant new builds are far from using most efficient technologies (e. g. CHP), therefore keeping energy intensive structures. But fossil fuels could be sold on international markets if spared by having more efficient energy infrastructures.
As shown by the high energy intensity of its economy, Iran has large potentials for energy saving and efficiency. In order to highlight and better identify this potential the paper contrasts a high efficiency scenario in all sectors of energy transformation and consumption with a possible "business as usual" development.
Using a bottom-up approach, the analysis provides a sector-by-sector perspective on energy saving potentials. These can be utilised on the demand side especially in the transport sector (fuels) and in households (electricity for appliances, natural gas for heating). Electricity generation bears efficiency potentials as well.
We conclude that Iran, but also the international community, would benefit on various levels from a more energy-efficient Iranian economy: Energy exports could increase, generating more foreign currency and reducing the pressures on international oil and gas prices; energy consumption would decrease, leading to lower needs for nuclear energy and for subsidies to Iranian people, as well as to a reduction of the high external costs entailed by fossil fuels combustion (smog in cities, environmental stress).
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.
Under the framework of the UN framework convention on climate change (UNFCCC) and its Kyoto Protocol the targets and strategies for the second and third commitment period ("post-2012") have to be discussed and set in the near future. Regarding the substantial emission reductions that have to be shouldered by the industrialized nations over the next two decades it is evident that all available potentials to mitigate greenhouse gas (GHG) emissions have to be harnessed and that energy efficiency has to play a key role.
To substantiate this we developed a comprehensive scenario analysis of the EU 25s energy system and other greenhouse gas emissions until 2020. Our analysis shows which key potentials to mitigate greenhouse gas emissions are available, by which policies and measures they are attainable
and which will be benefits of greenhouse gas mitigation measures.
By this analysis we show the mayor role of energy efficiency in all sectors and all member states. We demonstrate that a reduction of EU 25 greenhouse gas emissions by more than 30 % by 2020 is feasible, reasonable and - to a large extent - cost effective. We also develop a comprehensive policy package necessary to achieve ambitious Post-Kyoto targets.
The scenario analysis results in a clear identification of the needed strategies, policies and measures and especially the relevance of energy efficiency to achieve the necessary ambitious greenhouse gas reduction targets. It also clearly shows the costs and the benefits of such a policy compared to a business as usual case.
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?
There is an extensive potential for GHG emission reductions in the new EU member states and the EU accession countries by improving energy efficiency, investing in renewable energy supply and other measures, part of which could be tapped by JI. However, the EU Emissions Trading System (EU ETS) and especially the recently adopted "Linking Directive" is probably going to have a significant impact on this JI potential. Especially two provisions are important:
The baseline of a project has to be based on the acquis communautaire, the environmental regulations of which are substantially higher than the Accession Countries' existing ones. Projects, which directly or indirectly reduce emissions from installations falling within the scope of the EU ETS, can only generate certificates if an equal number of EU allowances are cancelled. JI is thus put into direct competition with the EU ETS. In this paper we analyse the impact of these provisions first in theory and then country by country for six Central and East European countries that recently acceded the EU or are candidates for accession. As a result, we give an overview of the potential and the limitations of JI as an instrument for achieving emission reductions in the selected Accession Countries and provide important overview information to policy makers.
International consensus is growing that a transition towards a low carbon society (LCS) is needed over the next 40 years. The G8, the Major Economies Forum on Energy and Climate, as well as the Ad Hoc Working Group on Long-term Cooperative Action under the United Nations Framework Convention on Climate Change, have concluded that states should prepare their own Low-emission Plans or Low-emission Development Plans and such plans are in development in an increasing number of countries.
An analysis of recent long-term low emission scenarios for Germany shows that all scenarios rely heavily on a massive scale up of energy efficiency improvements based on past trends. However, in spite of the high potential that scenario developers assign to this strategy, huge uncertainty still exists in respect of where the efficiency potentials really lie, how and if they can be achieved and how much their successful implementation depends on more fundamental changes towards a more sustainable society (e.g. behavioural changes).
In order to come to a better understanding of this issue we specifically examine the potential for energy efficiency in relation to particular demand sectors. Our comparative analysis shows that despite general agreement about the high importance of energy efficiency (EE), the perception on where and how to achieve it differ between the analysed scenarios. It also shows that the close nexus between energy efficiency and non-technical behavioural aspects is still little understood. This leads us to the conclusion that in order to support energy policy decisions more research should be done on energy efficiency potential. A better understanding of its potential would help energy efficiency to fulfil its role in the transition towards a LCS.
Several low-carbon energy roadmaps and scenarios have recently been published by the European Commission and the International Energy Agency (IEA) as well as by various stakeholders such as Eurelectric, ECF and Greenpeace. Discussions of these studies mainly focus on technology options available on the electricity supply side and mostly omit the significant challenges that all of the scenarios impose on the energy demand side.
A comparison of 5 decarbonisation scenarios from 4 of the most relevant recent scenario studies for the EU shows that all of them imply significant efficiency improvements in traditional appliances, usually well above levels historically observed over longer periods of time. At the same time they assume substantial electrification of transportation and heating. The scenarios suggest that both of these challenges need to be tackled successfully for decarbonising the energy system.
With shares of renewable electricity reaching at least 60 % of supply in 2050 in almost all of the decarbonisation scenarios, the adaptation of demand to variable supply becomes increasingly important. This aspect of demand side management should therefore be part of any policy mix aiming for a low-carbon power system.
Based on a quantitative analysis of 5 decarbonisation scenarios and a comparison with historical evidence we derive the (implicit) new challenges posed by the current low-carbon roadmaps and develop recommendations for energy policy on the electricity demand side.
The Port of Rotterdam is an important industrial cluster mainly comprising of oil refining, chemical manufacturing and power and steam generation. In 2015, the area accounted for 18 % of the Netherlands' total CO2 emissions. The Port of Rotterdam Authority is aware that the port's economy is heavily exposed to future global and EU decarbonization policies, as the bulk of its activities focuses on trading, handling, converting and using fossil fuels. Based on a study for the Port Authority, our paper explores possible pathways of how the industrial cluster can keep its strong market position in Europe and still reduce its CO2 emissions by 98 % by 2050. The "Biomass and CCS" scenario assumes that large amounts of biomass can be supplied sustainably and will be used in the port for power generation as well as for feedstock for refineries and the chemical industry. Fischer-Tropsch fuel generation plays an important role in this scenario, allowing the port to become a key cluster for the production of synthetic fuels and feedstocks in Western Europe. The "Closed Carbon Cycle" scenario assumes that renewables-based electricity will be used at the port to supply heat and hydrogen for the synthetic generation of feedstock for the chemical industry. The carbon required for the chemicals will stem from recycled waste. Technologies particularly needed in this scenario are water electrolysis and gasification or pyrolysis to capture carbon from waste, as well as technologies for the production of base chemicals from syngas. The paper compares both scenarios with regard to their respective technological choices and infrastructural changes. The scenarios’ particular opportunities and challenges are also discussed. Using possible future pathways of a major European petrochemical cluster as an example, the paper illustrates options for deep decarbonisation of energy intensive industries in the EU and beyond.
The German federal state of North Rhine-Westphalia (NRW) is home to important clusters of energy-intensive basic materials industries. 15% of the EU's primary steel as well as 15% of high-value base chemicals are produced here. Together with refinery fuels, cement, lime and paper production (also overrepresented in NRW) these are the most carbon-intensive production processes of the industrial metabolism. To achieve the ambitious regional and national climate goals without relocating these clusters, carbon-neutral production will have to become standard by mid-century. We develop and evaluate three conceptual long-term scenarios towards carbon-neutral industry systems for NRW for 2050 and beyond:
* a first scenario depending on carbon capture and storage or use for heavy industries (iCCS),
* a second scenario sketching the direct electrification of industrial processes (and transport) and
* a third scenario relying on the import of low carbon energies (e.g. biomass, and synthetic fuels (like methanol) for the use in industries and transport. All scenarios share the assumption that electricity generation will be CO2-neutral by 2050.
For all three scenarios energy efficiency, primary energy demand for energy services and feedstock as well as the carbon balance are quantified. We apply a spatial-explicit analysis of production sites to allow for discussion of infrastructure re-use and net investment needs. Possible symbiotic relations between sectors are also included. The robustness of the three conceptualised future carbon-neutral industry systems is then analysed using a multi-criteria approach, including e.g. energy security issues and lock-ins on the way to 2050.
Following the decisions of the Paris climate conference at the end of 2015 as well as similar announcements e.g. from the G7 in Elmau (Germany) in the summer of 2015, long-term strategies aiming at (almost) full decarbonisation of the energy systems increasingly move into the focus of climate and energy policy. Deep decarbonisation obviously requires a complete switch of energy supply towards zero GHG emission sources, such as renewable energy. A large number of both global as well as national climate change mitigation scenarios emphasize that energy efficiency will likewise play a key role in achieving deep decarbonization. However, the interdependencies between a transformation of energy supply on the one hand and the role of and prospects for energy efficiency on the other hand are rarely explored in detail.
This article explores these interdependencies based on a scenario for Germany that describes a future energy system relying entirely on renewable energy sources. Our analysis emphasizes that generally, considerable energy efficiency improvements on the demand side are required in order to have a realistic chance of transforming the German energy system towards 100 % renewables. Efficiency improvements are especially important if energy demand sectors will continue to require large amounts of liquid and gaseous fuels, as the production of these fuels are associated with considerable energy losses in a 100 % renewables future. Energy efficiency on the supply side will therefore differ considerably depending on how strongly the use of liquid and gaseous fuels in the various demand sectors can be substituted through the direct use of electricity. Apart from a general discussion of the role of energy efficiency in a 100 % renewable future, we also look at the role of and prospects for energy efficiency in each individual demand sector.
Die Transformation des Energieversorgungssystems zu einer dekarbonisierten Energiebereitstellung bedingt ein koordiniertes Zusammenspiel der Sektoren Strom, Wärme und Verkehr. Dabei ist die Kopplung des Stromsektors mit dem Wärmesektor eine der entscheidenden Maßnahmen bei der Transformation. Die Aufnahme von Wind- und Sonnenenergie in das Netz kann durch genaue Einspeiseprognosen optimiert werden, die Kopplung zum Wärmesektor mittels Wärmepumpen und Power-to-Heat (Heizstab) ermöglicht die weitere Flexibilisierung der Nachfrageseite. Diese Interaktion wird durch intelligente Lösungen der Systemtechnik für das Energie- und Netzmanagement ermöglicht. Die Entwicklung von entsprechenden Anreizsystemen, Marktmechanismen und Geschäftsmodellen ist ebenfalls erforderlich, um diese Kopplung auch wirtschaftlich erfolgreich zu gestalten. Der Beitrag stellt das im Forschungsvorhaben "Interaktion EE-Strom, Wärme und Verkehr" erstellte 80-Prozent-Szenario für das Jahr 2050 vor und zeigt anhand von Beispielen zukünftige Anforderungen und Entwicklungen zu dieser Thematik auf.
Energy intensive industries are one of the fields in which strong increases of energy efficiency and deep decarbonisation strategies are particularly challenging. Although European energy intensive industries have already achieved significant energy and greenhouse gas reductions in the past, much remains to be done to make a significant contribution to achieving European as well as national climate mitigation targets of greenhouse gas emission reductions by -80% or more (compared to the baseline of 1990). North Rhine-Westphalia (NRW) is a European hotspot for coping with this challenge, accommodating more than 10% of the energy intensive industries of the EU28. It is also the first German state to have adopted its own Climate Law, enacting state-wide CO2 emission reductions by 80% until 2050 compared to 1990. The state government initiated the project "Platform Climate Protection and Industry North-Rhine Westphalia" to identify and develop the necessary far-reaching low carbon innovation strategies for energy intensive industries. Heart of the project was a dialogue process, which involved a broad spectrum of stakeholders from steel, chemical, aluminium, cement, glass and paper producing industries. Besides enhancing and broadening the knowledge on high efficiency and low-carbon technologies within industries, the aim was to explore possible pathways and preconditions for the application of these technologies in energy intensive industries as well as to strengthen the motivation of companies for initiatives and investments in technologies with lower CO2 emissions. The results of the dialogue shall provide a basis for a possible low-carbon industry roadmap NRW and may also serve as an example for other industrialized regions in the EU and globally. The paper sketches the structured dialogue process with the stakeholders from companies as well as industrial associations and presents the learnings regarding the engagement of energy intensive industries into ambitious climate policies on a regional level. These include existing limitations as well as chances in the respective sectors on the state level, regarding their economic and technical structures as well as their innovation systems. The findings are based on more than a dozen stakeholder workshops with industry companies and more than 150 individual representatives of NRW's energy intensive industries as well as on background research in the initial phase of the project.
Heat integration and industrial symbiosis have been identified as key strategies to foster energy efficient and low carbon manufacturing industries (see e.g. contribution of Working Group III in IPCC's 5th assessment report). As energy efficiency potentials through horizontal and vertical integration are highly specific by site and technology they are often not explicitly reflected in national energy strategies and GHG emission scenarios. One of the reasons is that the energy models used to formulate such macro-level scenarios lack either the necessary high technical or the spatial micro-level resolution or both. Due to this lack of adequate tools the assumed huge existing potentials for energy efficiency in the energy intensive industry cannot be appropriately appreciated by national or EU level policies. Due to this background our paper describes a recent approach for a combined micro-macro energy model for selected manufacturing industries. It combines national level technical scenario modelling with a micro-modelling approach analogous to total site analysis (TSA), a methodology used by companies to analyse energy integration potentials on the level of production sites. Current spatial structures are reproduced with capacity, technical and energy efficiency data on the level of single facilities (e.g. blast furnaces) using ETS data and other sources. Based on this, both, the investments in specific technologies and in production sites are modelled and the evolvement of future structures of (interconnected) industry sites are explored in scenarios under different conditions and with different objectives (microeconomic vs. energy efficiency optimization). We further present a preliminary scenario that explores the relevance of these potentials and developments for the German steel industry.
This paper draws upon an extensive transdisciplinary scenario development in the context of the stakeholder oriented preparation of the climate protection plan of the German federal state North Rhine-Westphalia, which is home to the most important heavy industry cluster in Europe. In that context we developed differentiated bottom up climate change mitigation strategies and scenarios for the major energy intensive industries aluminium, iron and steel, cement, lime, paper and steam cracker for olefin production together with representatives of industry as well as society.
Nach einer langen Phase der Stabilität ist die Stromwirtschaft in den vergangenen 15 Jahren stark in Bewegung geraten. Zunächst stand der Wechsel von staatlich überwachten und regulierten Gebietsmonopolen hin zu liberalisierten Erzeuger- und Verbrauchermärkten an. Im Moment befinden wir uns in einem ähnlichen Umbruch, weg von konventioneller hin zu erneuerbarer Energieerzeugung.
Im vorliegenden Beitrag soll der Leitfrage nachgegangen werden, ob die Paradigmen der einzelnen Phasen miteinander vereinbar sind, welche noch immer ihre Daseinsberechtigung haben und welche modifiziert werden sollten.
The EU aims to become the first climate neutral continent. To achieve this goal, the industry sector needs to reduce its GHG emissions to net zero or at least close to net zero. This is a particularly challenging task due to the high energy demand especially of primary materials production and the little potential to reduce this energy intensity when switching to other production processes based on electricity or hydrogen. In order to identify robust strategies for achieving a net-zero-compatible industry sector, the paper at hand analyses the transformation of the industry sector as described by a number of recent climate neutrality scenarios for Germany. Apart from overall industry, a focus is set on the sectors of steel, chemicals and cement. The analysed scenarios show very deep GHG emission reductions in industry and they appear to be techno-economically feasible by the mid of the century, without relying on offsets or on shifts from domestic production to imports. The scenarios agree on a suite of core strategies to achieve this, such as direct and indirect electrification, energy efficiency and recycling as well as new technological routes in steel making and cement. The scenarios differ, however, regarding the future mix of electricity, hydrogen and biomass and regarding the future relevance of domestic production of basic chemicals.
