The future of the energy transition in Germany
Energy, Sustainability and Society volume 4, Article number: 15 (2014)
Although the goals of the country’s energy transition (Energiewende) are widely accepted in Germany, the specific route to get there is itself a matter of great controversy. The individual measures that are part of the energy transition policy and the questions of how they interact and how they are embedded in the European context are objects of controversial scientific and public debate. Most recently, the consequences for the price of electricity have, in particular, been discussed intensely. Against this backdrop of wide-ranging criticism, the future course for promoting renewable energy will soon be set. The German Renewable Energy Sources Act (the Erneuerbare-Energien-Gesetz, EEG), which is the main instrument of energy transition policy with its feed-in tariffs, is supposed to be fundamentally revised in the course of this year. A precondition for achieving a coherent further development of the energy transition policy and for receiving the sound support of a critical public is that the long-term consequences of political decisions on a complex sociotechnical energy system be taken into account. The requirements of such a system are not satisfied by policy approaches or recommendations that target short-term effects or that are perceptions of problems extrapolated from individual sectors. On the basis of its integrated research on the energy transition, researchers from the Helmholtz Alliance Energy-Trans take a stand on current important controversial issues from the energy transformation and specify fundamental challenges to shaping a sustainable energy transition policy.
The energy transition: a long-term project and a challenge to the system
The energy transition in Germany is nothing less than the restructuring of the entire energy supply in the sectors’ electricity, heat, and transportation in a highly industrialized country. This comprehensive reorganization is a task for generations, and yet the fundamental framework has to be created today. Although there continues to be a high level of approval in the general public [–] and among all political forces [], essential components of the German energy transition policy are themselves currently being subject to criticism, some of it very intense. The focus of this criticism is most frequently on the renewable energy supports provided for the generation of electricity, which take the form of feed-in tariffs permitted by the Renewable Energy Sources Act (Erneuerbare-Energien-Gesetz (EEG)).a Challenges to the energy transition go, however, far beyond this. What is required is a long-term process of transforming a complex sociotechnical system [,] in which the goal is to set the course of change so that tomorrow’s energy supply works, its consumption of resources, and its impact on the environment are limited to a sustainable level, and, in the process, efficiency and social acceptance are safeguarded. Political activity should always keep this long-term systemic perspective in sight. Policy that is directed toward short-term, purely sectoral based indicators, such as the allocation of costs in the EEG (the levy or surcharge), does not do this justice [,].
Energy transition policy under scrutiny
A complex and sweeping enterprise such as the energy transformation project must nonetheless - and quite rightly - justify to a critical public that the overall policy framework for such substantial structural changes is correctly set and confirm that unnecessary costs are not being imposed on the national economy. Agreement on the goals of restructuring always has to come at the beginning of reforms []. The instruments for the subsequent implementation should be continuously adapted in accordance with a process-based control strategy that is open for corrections [,], since it is impossible today to foresee every future challenge and necessary measure. For this reason, the review that is currently underway, particularly of the EEG, is in principle to be welcomed. Regular corrections and realignments are inevitable if new but suboptimal routes of development are to be prevented from becoming stabilized and rigid.
The cost of the renewable energy expansion: an objective debate is essential
The debate over reforms that has started in the meantime is falling short. It is strongly focused on the power sector, the current consumer prices, and the influence of the EEG levy on these prices. This reductionism blocks our view both for the socioeconomic connections and for the real challenges to energy policy. The heat and transportation sectors are also central to a sustainable transformation of our energy system, not just the power supply [].b From the perspective of the national economy, the costs that are at issue cannot be limited to those printed right on the electricity bill. Other external costs - in addition to CO2, there are also local environmental issues - as well as special benefit dimensions, such as learning curve effects of technology development, also have to be taken into consideration [,–]. Furthermore, to be fair, every form of subsidy for an energy carrier has to be taken into consideration, even those via financing channels other than the price of electricity []. The current debate about the price of electricity does not take all of this into account and turns our attention for day-to-day political matters to issues that are not at the heart of the challenges facing the transformation. Against this backdrop, it is clear that a more objective debate about costs is urgently necessary, as is a reorientation of the reform agenda.
Support for renewables still sensible
There are still good reasons to continue a policy of supporting renewable energy, at least in principle. Neither have we come even remotely close to reaching our ambitious goals for expanding it, nor do the current market prices cover the relevant costs to the national economy, which would represent the possibility for the market alone to maintain undistorted, fair technological competition to determine the most favorable manner of generating energy [,,]. The additional costs for renewable energy, i.e., those beyond the price achieved on the power exchange, will drop again considerably anyway. The exchange prices, which in the medium term will be oriented on the long-term marginal costs of the conventional power plants still producing electricity - and which will rise again after the excess capacity is disposed of - contribute to this. Likewise, a more robust European Union (EU) emissions trading system would have a corrective effect on the distorted exchange prices. For these reasons (incomplete internalization of external effects, subsidies for conventional power generation, electricity prices on the exchange that are too low) and because of the neglect of the future price development, renewable energy continues to exhibit strategic disadvantages in the public’s perception of costs and in a comparison of market prices with conventional energy carriers, which says nothing about their actual long-term competitiveness []. In this respect, the support for renewables is currently not up for disposal, but it is up for renewed goal-oriented development. This has to be undertaken with due regard for the possible effects of distortions of support policies for renewables []. Consequently, it must be ensured that the goal is achieved in a more cost-efficient manner, not just an effective one [].
Keeping an eye on the social distribution of costs
The discussion of the costs and utility of the energy transformation for society cannot be restricted to their appropriate amounts. Their distribution to individuals, groups, and regions belongs to the challenges facing responsible policy making. In particular, the distribution of the burden resulting from the energy transformation may not be intransparent or in contradiction to the fundamental values of fairness. Above all, the extensive and sometimes objectively groundless number of exceptions for industry from the financing of the expansion of renewable energy by all the consumers of electricity meets with substantial misgivings [,] and has become the object of European proceedings for inappropriate state aid (see the following section) []. The EEG-levy exceptions for industryc have been repeatedly expanded in the past. They should - independent of the requirements of European law - rapidly be limited to a realistically tenable amount that is aligned on the proven dangers to international or intermodal competitiveness [,,]. A company’s energy consumption, the measure currently used by the EEG, is an unsuitable indicator for this purpose.
Conformity of the EEG with European state aid regulations
A current object of scrutiny with regard to European regulations is the preferential treatment provided for by the EEG. The prohibition of state aid forbids the use of state funds to provide preferential treatment to certain enterprises or branches regardless of their nature if it distorts competition in Europe’s internal market or threatens to do so (Article 107(1), Treaty on the Functioning of the European Union (TFEU)). This leads to requirements for structuring of the renewable energy policy. The European Court of Justice (ECJ), however, decided in 2001 that the law regulating the feed in of electricity of that time conformed to EU state aid regulations because it did not constitute state aid. This law obliged energy supply companies and network operators to purchase electricity from renewable sources of energy at a price set by law - which was above the market price - and to pass on the additional costs in a compensation system run by the network operators and energy suppliers. This was the case since no state aid was transferred to the companies that produced the power either directly or indirectly []. Yet, this decision does not provide a free pass for every kind of further development of the EEG (see e.g., []). Decisive is, first, whether the financing and compensation mechanism in the present EEG represents an organization of financial streams that can be assigned to the category of the state sphere of financing and thus whether the act of providing state aid is present at all.d Even then, this might not have any consequences insofar as there is no threat of a distortion of competition or it is at least shown to be a justified exception according to European law, which in principle has also been acknowledged by the European Commission with regard to promoting the use of renewable energy ([], p. C 74]). The Commission, however, affirms that the EEG constitutes state aid and for this reason also doubts that the so-called green power privilege (§ 39 EEG)e and the EEG-levy exemptions for energy-intensive companies (§ 40 ff. EEG) conform to European law because it suspects a distortion of competition in both cases ([], p. C 74 et seq.]). The Commission has therefore recently initiated a formal investigation of Germany.f With regard to the issue of whether the EEG system of supports and compensation constitutes state aid, the Commission’s legal opinion is far from compelling because the role of the state authorities is very limited, no state or semistate fund is established, and the system using a levy and a reduction in charges continues to rely on private law for participants to assert their claims.g There are therefore good reasons to assume that the current EEG system will not be subject to the scope of EU rules on state aid.h Yet, it is by no means guaranteed that the EEG system will be found to conform to these rules. If the EEG mechanism is found to have the character of state aid, then EU law offers possibilities for justifying its form (e.g., Article 107 (3) lit b TFEU) or for structuring the aid in a manner that conforms to EU law.i To do the latter, environmental guidelines of the European Commission [] are employed, which are currently being revised parallel to the legal actions [], completely confusing the future legal situation. The compatibility of the EEG with European rules on state aid is essential for the further development of the EEG. Until these difficult legal issues are clarified, which can possibly drag on for years until there is another decision by the European Court of Justice,j the pending reform of the EEG must be pushed on keeping in mind the issue of conformity to European law, not however according to the Commission’s unauthoritative legal stance. This means a consistent curtailment of the present volume of the EEG-levy exemptions for the power-intensive fields of manufacturing, restricting application of the rule to those cases where its application would obviously result in distortion of competition. Attention must be paid to ensure that the selection of branches of the economy that are given relief and the amount of the relief are in conformity to the EU regulations on state aid. Furthermore, other examples in the EEG of preferential treatment (e.g., the green power privilege) should be examined from the perspective of nondiscriminatory competition in the European single market. Both of these have already been agreed upon in the current government’s coalition agreement and may well point in the right direction in terms of European law.
Maintaining a social balance
The social consequences of the energy transition policy should always be taken into consideration, yet without playing off social policy against energy, environmental, and climate policy [–]. Those who are socially weak must be able to keep up during the restructuring of the energy system.k Appropriate relief from the EEG levy can even be provided to private households, by the way, by reform measures that are advisable in terms of energy policy anyway. This includes making the European emissions trading system more robust (see ‘Strengthening the EU emissions trading and use the chances offered by European inclusion’ section), which would lead to higher prices in the electricity market and thus correspondingly to a lower cost differential that would have to be covered by the levy. Another effect would be the decrease in the excessive privileges enjoyed by industry (see ‘Keeping an eye on the social distribution of costs’ and ‘Conformity of the EEG with European State Aid Regulations’ sections) in the context of the EEG levy, which also could lower the corresponding burden on private households.l Furthermore, measures focused on policies to improve energy efficiency (see ‘Urgent fields of action other than the generation of electricity: pushing energy efficiency’ section) constitute a sensible contribution to providing relief to lower-income groups without compromising the goals of the energy transition [,].
How to continue with the German Renewable Energy Sources Act?
The success of the present philosophy for providing support in the EEG has in the meantime reached its limits, making a reorientation necessary. The size of the EEG levy is, however, not an unqualifiedly suitable measure for political action for it depends on numerous distorting factors, such as the exchange price and the extent to which levy reductions are granted (e.g., for industrial use and for self-generated electricity) []. The EEG levy does not immediately reflect the cost of the transition to renewables to the entire economy, which also includes any later consequences of the energy supply that are ecological or social in nature []. The expert commission conducting the monitoring process called ‘Energy of the Future’ has made suggestions for indicators that are far more suitable []. The envisaged reform of the EEG should therefore abstain from organizing a simple limit to the levy. A revision of the Act must not be driven by the lack of a unit for measuring the cost of the EEG levy, but must initiate a structural reform that is sustainable in the medium term. Such a reform must be based on a comprehensible analysis of the problem and a clear ranking of the political goals []. After providing supports for 20 years, it is right to reset the priorities in the direction of sustainable and less costly technology. In particular, consideration should be given to the consequences the EEG’s market incentives have on the regional distribution of production (e.g., primarily on the windy costal locations or rather closer to the consumption in the country’s interior). In doing so, neither support for renewable energy as such should be challenged nor should the general framework for urgently required investments be subject to all too abrupt changes.
The challenge of designing the future electricity market
Following a reform of the EEG, thought must be given to a new holistic design of the electricity market in the medium term. Currently, there is no reason to undertake any far-reaching interventions in the framework of the electricity market that would bind us for a long term. The current low prices on the power exchange that are the object of complaints because they are thought to be problematic for operators of conventional power plants are the expression - in a manner, completely in keeping with the market - of an excess supply of capacity for generating electricity and of the lack of impulses from the European emissions trading system (see ‘Support for Renewables Still Sensible’ section) but not of the unsuitability of the present market design. Restraint is therefore advisable with regard to considerations of the short-term introduction of capacity mechanisms that are supposed to give additional income to conventional power plants at the consumers’ expense today because of fears that there will be bottlenecks in the future. Although it is necessary for volatile renewable forms of energy to be subject to scrutiny and study in order to ensure the long-term supply in future periods, there is no acute need for political action.m The debate has turned much too quickly to the question of how a mechanism promoting the expansion of capacity could look in concrete terms, even before the necessity of such an institutional innovation has been viably justified at all. The available time should rather be utilized to make a thorough determination of the problems that can actually be expected to afflict a future secure supply of power and to prepare the design of the future electricity market accordingly. To solve such capacity-based supply problems, the potential savings from making demand more flexible, from expanding the network and storage, and from the cogeneration of heat and power should be examined as a matter of principle in addition to considering a possibly expensive realignment of the design of the electricity market []. Constant attention must be given to an efficient organization of the various markets in order to keep the costs of the energy transition under control in this respect, for example, for the flexibility reserves that will be necessary in the future [].
Urgent fields of action other than the generation of electricity: pushing energy efficiency
Achieving an efficient use of the available energy is, after the expansion of renewable energy, the most important task in the field of power supply. The pace of energy efficiency - which until now has been inadequate - must be forced considerably.n Estimates made by dena (The German Energy Agency or Deutsche Energie-Agentur) assume that the use of electricity in private households can be decreased by up to 25% as a result of the use of energy-efficient devices and optimized consumer behavior [].o The substantial potentialp for improving technical efficiency throughout the entire electricity sector - in the generation, transformation, and transportation - and for saving power have to be utilized as far as this can be done in a cost-effective manner.q This mitigates the necessity of replacing energy carriers and limits the necessary expansion of renewable energy. Precisely, the power prices criticized as being high contribute in a market-based system as an incentive for investments in energy efficiency and for saving energy. The price of electricity is not a stroke of fate but a sign of scarcity that admonishes us to adopt efficient consumer behavior, which can effectively limit the cost burden. Active competition in the power exchanges and a change in provider by consumers can contribute to easing the burden in a manner in keeping with the market []. As a consequence, interventions in the price of power that are motivated by social reasons or industrial policy should not be pursued [].
Further develop grids and storages as complementary components of energy infrastructure
Storage and networks constitute important complementary forms of infrastructure in the power sector and must be further developed to enable them to adopt modified and entirely new tasks in the sustainable energy supply system of tomorrow. In this way, the reserve capacity that will be needed in the future in addition to the renewable capacity will be reduced, and the degree of utilization, especially of feature-dependent renewable energy (sun, wind), will be improved. A much improved coordination between the expansion of generation and the network infrastructure will make a necessary contribution to this [,]. At the same time, another goal must be an efficient management of the network, in which power suppliers as a matter of principle take the needed transportation costs in the network into account when they make decisions about future locations [,]. The optimization of the entire system (generator plants, networks, storage) will at the same time reduce the pressure on generation, especially on the supports for renewable sources. It is obvious that the EEG alone cannot bear the responsibility for the performance and for the costs of the difficult system transformation in the power sector.
Push the energy transition in the sectors’ heat and transportation as well
In order to achieve the goals of the energy transition, substantial efforts are needed in the fields of heat and transportation in addition to the measures in the area of power supply. Both the supply of heat from renewable energy and the energy efficiency of buildings unjustly take a back seat in the attention of both the public and politicians to that given the supply of power [–]. In light of the special potential for savings in those areas, it is urgent that a coherent plan be developed as to how measures to improve efficiency in the building stock can be linked with the use of renewable sources for the generation of heat [,]. At the same time, it is of great importance for the acceptance of such policy measures that questions regarding allocation, in particular, between renters and property owners, as well as incentive problems [,] be given full consideration [,]. Similarly, systematic incentives are to be developed in the area of transportation []: to complement the ambitious formulation of political goals, instruments have to be created quickly to implement such incentives. We are unable in this context to delve deeper into these extremely important complementary modules in the energy transition.
Strengthen the EU emissions trading and use the chances offered by European inclusion
The integration of Germany’s energy policy in the European framework deserves, if nothing else, to be paid attention to. Germany’s future energy policy has to consistently take advantage of the chances offered by European integration. This means that a balance must be struck between European integration and national energy transition policy. The German energy transition is appropriately integrated in European climate policy, in the expanded use of renewable energy, and in energy efficiency policy until at least 2020, via the common European framework of goals []. Particularly from the German perspective, adhering to its separate goals for expanding the use of renewable energy and for improving energy efficiency can be sensible at the European level and even beyond 2020 if this means that externalities other than the reduction of CO2 emissions can be addressed. This is in fact plausible [,] since globally numerous environmental damages or risks, even interregionally relevant ones, are linked to the acquisition and use of nonrenewable energy carriers, starting with the decomposition of the energy carriers (e.g., the consumption of land by strip mining of coal), including their use to generate electricity, heat, and power (particulate emissions, nuclear incidents) or the problematic of import risks that have not been priced in, up to disposal (radioactive waste).r At the European level, interactions between the expansion of renewable energy with the fixed volume goal for CO2 set by the European emissions trading scheme must definitely be taken into account in order to avoid overendowing them with certificates in the future [,].s The European emissions trading scheme - used as an internalization lever for climate follow-up costs - is one of the most important instruments of environmental energy policy in the European context. It is essential that its functioning be retained and strengthened. An effective emissions trading system contributes to the reduction in distortions in competition that results in a burden on environmentally friendly renewable energy and at the same time prevents a fall in the prices on the power exchange []. Furthermore, strong European coordination of the national measures regarding energy policy will contribute to opening up synergies and reducing costs. For the areas of the EU internal market and the trans-European networks, the authority that the EU already has should be utilized systematically. Regarding the expansion of renewable energy, in contrast, it appears more realistic to place one’s bets on a decentralized process of convergence under the umbrella of EU objectives, such as through the linkage of the national systems of supports [].
The role of the state in the energy transition
The preceding developments concerning energy policy have engendered numerous misgivings with regard to the strong role played by the state and to the regulation of the energy sector of the economy that is increasingly being perceived as being aloof of the markets. State interventions are, however, indispensable where various market failures appear in the energy sector. It is necessary for corrective interventions to be taken where the current market prices do not reflect the social truth either economically or ecologically. Today’s infrastructure consisting of power plants and networks and the corresponding regulatory framework has been optimized for the centralized generation of electricity using continuously available energy carriers. The long-term investments that have been made lead to the conviction that the shifting of the system to decentralized, renewable technology whose production is volatile does not make any business sense even if it is desirable for the economy overall. Finally, barriers in technology development, restrictions in the capital markets, problems of local acceptance, and protracted approval procedures impede the necessary changeover and cannot be overcome solely by market-based mechanisms [,,]. There are therefore good reasons for the state to currently play a leading role in the energy transition.
Stable framework instead of a zigzag route
The energy transition is a large-scale societal project requiring private and public investments in the billions. The risk involved must especially be born privately, and the investments must point in the right direction for the entire economy. Politics bears the responsibility for both. We therefore need clear and unambiguous incentives as well as a framework that is stable for the medium term and that refrains from constantly changing the rules of law and the conditions of investment. This will also prevent investments from being depreciated post hoc that were made in confidence in the continuance of energy policy rules. Efforts at reform therefore always have to take into consideration the commandment to observe the ‘constancy of economic policy’ [].t
Coordinating the energy transition in the federal system
The federal system of the Federal Republic of Germany offers great chances for innovative decentralized solutions. The cities, regions, and states form a framework suitable for the development of innovative solutions adapted to decentralized forms of technology (competitive federalism). Moreover, the guarantee of community self-management provides the institutional basis for active local energy policies that serve as role models [,]. Making the energy transition a success does not only depend on maintaining or expanding the opportunities for decentralized decision makingu but also on optimizing the overall system and keeping the costs as low as possible while maintaining the goal. The location-related consequences of renewables for man and nature must also be considered in a comprehensive manner.v To do this, we need effective and efficient coordination of all the levels (national, state, regional, and municipal) and space- and process-related management. This is even the case for setting the goals for expanding renewables that affect infrastructure planning (networks and storage) and the related costs. Currently, the goals of the federal and state governments diverge significantly from one another with regard to expanding renewables [–]. New instruments are needed so that better coordinated decisions can be made, such as for a federal climate protection act [], specialist technical planning at the federal level [], or a strengthening of the Federal Spatial Planning Act.w In this way, the necessary orientation for state and regional planning decisions could be made as a prerequisite for investors’ decisions on locations, unnecessary expansion costs could be avoided, and local disturbances by renewables could be limited. Not all spatial issues can be resolved, however, by central planning. The space and freedom for making market decisions, which are needed for achieving cost efficiency in spatial allocations, must be maintained as a matter of principle [].
Conclusion: the energy transition as a sustainability project
The German energy transition is being watched critically around the world. It will be judged by whether and how far it succeeds in organizing the comprehensive sustainability of the energy supply in a highly industrialized country within a reasonable period of time and in maintaining profitability, security of supply, environmental compatibility, and social acceptability in equal measure. The challenges posed by the transformation of such a complex system are considerable, and we are still at the beginning of a long path. The difficulties that arise may not be played down, and the task of overcoming them requires ongoing scientific support as well as intensive public participation []. In the course of the energy transition, today’s generations are investing in a sustainable system of energy supply. The energy transition is consequently an intergenerational contract. The temporally limited (additional) costs being borne today are supposed to lead to permanently lower costs and risks tomorrow. This goal makes the energy transition into an outstanding sustainability project. For this reason, it also continues to deserve our full support.
aThe German Renewable Energy Sources Act (EEG) gives priority to feeding electricity from renewable sources into the power grid and guarantees firm rates of remuneration for this electricity (feed-in tariffs). On the discussion about the EEG, see e.g., [,].
bIn the following, the authors of this article also focus their attention on the power sector since we shall primarily refer to the current power-related controversies about energy policy in Germany.
cLarge industrial consumers of electricity are required only to pay a strongly reduced EEG levy and are thus largely freed from financing the system providing support for renewables.
eThe so-called green power privilege (§ 39 of the EEG-Act) establishes a particularly reduced EEG-surcharge for suppliers only if 50% of the electricity portfolio is sourced from domestic renewable electricity. This might discriminate between domestic and imported electricity from renewable sources produced in similar plants.

gSee only [71, p. 317]. On the continued absence of involvement of the state sphere of financing for the EEG-Act 2012, see also [].
iThe determination that the support and compensation system in the EEG had the character of state aid would have disagreeable consequences for Germany even if a justification according to European law were successful. Any new aid would always have to be notified in advance and could only be granted following approval by the Commission (Article 108 (3) TFEU: ban on implementation). For the period of time from the introduction of the aid until its approval, there is the threat of repayment claims. On this, see [] with extensive references to the relevant verdicts of the European Court of Justice.
jAustria’s current suit against the Commission’s decision of 8.3.2011 (C 24/2009, COM (2011) 1363 final) will presumably point the way ahead, which is over Austria’s law on ecological electricity.
lThe fact that aid models other than that using the EEG’s feed-in remuneration could even increase the burden is shown in [].
nSee [,]. In the World Energy Outlook Special Report 2013, the International Energy Agency (IEA) calls improving energy efficiency to be, of the four most important measures for climate protection, that having the most leverage to avoid CO2.
pBy far, the greatest economic potential for savings in the period until 2020, according to a recent study by dena, is in the area of heat and fuels (over 16%), which is followed by motor fuels and not inconsiderable amounts of electricity (approximately 10%); see []. See also [].
qOn this important auxiliary condition for economic efficiency in addition to purely technical energy efficiency, see [].
rWhile renewables also contribute to avoiding or mitigating these nonclimatic (environmental) externalities, they admittedly also cause novel regional environmental costs with respect to nature conservation, animal protection, the landscape, waters, and residential environment, which have to be taken into consideration as a nonmonetary category of costs during such an expansion - see e.g. [].

The authors jointly conduct research in the Alliance ENERGY-TRANS established by the Helmholtz Association of German Research Centers. Alliance researchers examine the energy transition in Germany and the related demands it places on the transformation of the national and European energy system, especially from the perspective of societal demand and utility, and analyze the manifold interfaces between technical and social factors. The results should provide policy-oriented know-how for an efficient and socially acceptable organization of the future energy system. Further information can be found at http://www.energy-trans.de.
