Theoretical Understanding of Energy Transition in Germany Part 3 - Future of Germany's energiewende

Last week, I discussed four institutional arrangements theories that can explain how community initiative emerges and develops. In Germany, it is a combination of community- and state-oriented system where the former plays a fundamental role in initiating community RE projects whilst the latter is a key to expanding the scale of the RE project into national level. Today, the country produces about a quarter of its energy through RE (Oteman et al, 2014). This has contributed to both increased energy security and global climate change mitigation significantly. However, there are a number of constraints in further developing RE in Germany because of the issue of storage capacity (Energy Transition, 2015). In this post, I shall examine how the country will address the problem to further develop its Energiewende.

To begin with, let me define the key term. Storage capacity refers to the capacity of energy being stored for a certain length of time until utilized (Gawel et al 2015). In Germany, storage systems only meets 1h of demand today (Gullberg et al, 2014). The implication of this to Germany's RE is that Since wind and solar power, which dominates Germany's installed capacity of RE, only produce electricity when wind blows or the sunlight is available, there is a significant gap in the amount of production during the day. When both are unavailable, electricity shortfalls can occur, causing massive destruction not only to domestic individual life but also to industrial activities. Germany used to consider nuclear power as a means of combating the shortages before the Fukushima disaster, yet, they decided to complete demolition of nuclear power plants by 2020, reflecting a strong public opinion against the supposedly dangerous, risky energy source  (Gullberg et al, 2014).

Technically, storage capacity can be increased using batteries, hydrogen, methane, compressed air and pumped-storage hydropower. However, these are generally inefficient and very expensive therefore not cost-effective (Gullberg et al, 2014). I think it is true that investing in these costly technology regionally would do nothing but leave a significant debt. Nevertheless, Germany recently embarks on a novel strategy that could resolve their problem, namely, international cooperation in electricity exchange with Norway (Gullberg et al, 2014).

Norway is known for its extensive installation capacity of hydroelectricity due to its geomorphology (Gullberg et al, 2014). In fact, the country's electricity sector is already almost completely dependent upon hydropower therefore produces almost no GHG emissions (Statkraft, 2015). Obviously, the country does not need to further develop RE considering the fact that they are fully functioned by hydropower. However, since there is still a great potential for Norway to expand the system, other European countries perceive the nation as 'green battery', meaning they are able to store energy produced by RE in hydropower (Gullberg et al, 2014). Basically, Norway pumps water from a lower elevation to a reservoir at a higher elevation using electricity produced from RE In Germany. Then, this low-carbon electricity can be stored and released to produce electricity to sell back to Germany when electricity prices are high in shortfalls (mostly at night) (Deutsche Welle, 2015). I think this is a win-win solution both to Germany and Norway - the former for solving intermittency problems, and the latter for making money and compensating for its fossil-intensive sectors - transport and heating. This helps achieve Norway's commitment to increase its share of renewables in the 'energy' mix to 67.5% by 2020 (Note that it's not 'electricity').

Some critics say the cost of installing new facilities particularly international grid connection such as in the North Sea and the one connecting the North and the South is extremely high. This challenge can be further complicated when environmental activists join in to campaign for nature conservation in the area of high-volatile cables being installed. The most recent example of opposition is those emerging to the building of a pumped-storage hydro facility at Atdorf in Baden-Wuttemburg (Gullberg et al, 2014). Furthermore, some Norwegian disagree with the proposal because they fear that development of new grid systems will increase electricity prices and that the use of land and water for pumped-storage will potentially destruct natural environments. The former is very true because energy facility is public owned therefore any cost associated with the development / maintenance will be reflected upon electricity bills (Gullberg et al, 2014).

Nevertheless, I suppose that Germany needs to go ahead with the project simply because they have no other choices. All nuclear power plants are now due to be demolished by 2020, and the dirty fossil fuel, lignite, naturally rich in Germany, has attracted a massive public opposition concerning deforestation, pollution and climate change. Some may argue that installing further RE in Germany would help reduce the risk of electricity shortfalls. However, I believe that regional / international cooperation is more important than achieving national energy security by generating renewable energy by 100% because the latter is very vulnerable to regional climate. For example, if anomalous rainy weather continues across Germany even for a couple of days, it will certainly lead to electricity shortfalls in many parts of the region particularly where storage capacity is low. By contrast, if places are connected to each other energywise, regionally, nationally and internationally, this can reduce the possibility of sudden blackout because they can exchange energy whenever necessary.

What I think Germany needs to develop the above system, primarily with Norway, is the following. First, political commitment of both countries is essential in order to attract sufficient investment to develop new infrastructure such as the grid system. As discussed in the earlier posts, the state involvement plays a fundamental role in increasing the investor's confidence therefore ensuring financial backing. Secondly, public debate over the development of the technology is essential to reach an agreement that minimizes the socio-economic and environmental costs of the project. As Gawel et al (2015) perceive the Energiewende as 'a long-term process of transforming a complex sociotechnical system', energy transition needs to come with restructuring societal systems including the change of people's perspectives and behaviours. Thirdly, the distribution of the burden incurred by energy transition should be taken into consideration more seriously. Gawel et al (2015) argue that It sometimes may not be intransparent or in contradiction to the fundamental values of fairness. Indeed, some consider the additional cost incurred by installing RE under the FIT system as a implicit environmental taxation that does not differentiate between the rich and poor. Clearly, it depends on the scale of geography (regional, national and international), yet there need to be some serious discussions over equity at high political level.

To sum, Germany's energy transition in the next few decades need to put more focus on how they cooperate with other countries like Norway to derive a win-win energy strategy. In this way, each country both maximizes and benefits from their potential economically. Some economists may consider this as an example of semi-competitive market, which represents the situation where a fairly large number of companies compete with each other in the industry with slightly different products. In other words, countries produce energy using different technology which is the most appropriate there both technologically and economically and trade it in the international market. Despite electricity transmission causes energy loss over a long distance, I think electricity exchange is still a viable option within a certain geographical proximity. Any thoughts or questions will be much appreciated!

Theoretical Understanding of Energy Transition in Germany Part 2

Last week, I discussed brief theoretical analogy that explains how community energy can be developed. If you have not read it yet, you may find it useful to have a quick read though it from here. To recap some basic points, there are three different ways to describe the occurrence and opportunities for community initiatives; agency-oriented; structure approach; and biophysical conditions (Oteman et al, 2014). Among these, structure approach is considered the most appropriate because the governance of energy is managed through the combination of the following sets of institutional logics; market-oriented system; state-oriented system; community-oriented system; and corporatist association order (Oteman et al, 2014). Today, I will look into the structural aspects of Germany's energy transition considering the institutional arrangements theory.

Photo.1 Energy turbine in Germany (Reference: North East Windmills, 2013)

To begin with, let me clarify some key terminologies introduced above. Hall and Taylor (2006) define the theory as 'the formal / informal procedures, routines, norms and conventions embedded in the organizational structure of the polity or political economy'. In other words, it is a way of describing how politics is structured by non-political traits such as socio-cultural and economic aspects of the community. Oteman et al (2014) argue that the extent to which community initiatives become prosperous is highly dependent upon the degree of significance of each component. As I mentioned above, there are mainly four systems that can explain how initiatives are organized locally; market-oriented; state-oriented; community-oriented; and corporatist associational order. Now, let's explore each of these arrangements theory.

First of all, market-oriented system refers to a system in which the principle of dispersed competition and profit-making market players are the most influential actors (Oteman et al, 2014). It essentially favours larger market parties due to economies of scale therefore the entry of small-scale or non-profit players are almost impossible. Also, this provides little uniformity in rules and policies at local level since the government's intervention is limited. The consequence is lack of knowledge, resources and subsidies which are essential for community projects to be successful (Oteman et al, 2014). This further leads to lowering the availability of funding from private investors. Therefore, in this system, community initiatives are least likely to develop.

By contrast, in state-oriented order, a system is guided by hierarchical control with the government's intervention (Oteman et al, 2014). The advantages are the greater levels of funding, tenders and permission grants in comparison to the market-oriented system. However, it comes with some drawbacks such as little chance for new technology or experimental designs which do not fit into the institutional structure of rules and finance of the state (Oteman et al, 2014). In addition, there is sometimes friction in land use between the government and the locals because they do not always understand community values of land. For instance, if the government decides to cut and burn the part of local forests to construct solar PVs whilst local residents perceive natural beauty as one of the most valuable property of the community, the community incentives are likely to be lowered.

Next, community-oriented system is based on spontaneous solidarity of community actors (Oteman et al, 2014). Fundamentally, the incentives for community initiatives in this system are derived from their own experiences such as deforestation, pollution, security concern, and aspiration for socio-economic revitalization. In contrast to the state-oriented order, it leaves larger room for decentralized policy and local variation that is adjusted to specific circumstances, preferences or dominant ideas prevailing in the community. This enables to develop the local-specific knowledge and resources needed for the projects. Also, whether community initiatives develop capacity are counting upon the strength of the network among the community and other stakeholders. It provides good institutional space, namely, discrepancy freedom of community initiatives to decide autonomously about the design a project and its contents (Oteman et al, 2014). Nonetheless, some of the challenges they must face are limited funding from outside if the network is limited at the onset of projects, and voluntary attitudes of the locals are not always promising and therefore can deteriorate in long term.

Lastly, in corporatist associational order, a system is governed through an institutionalized and organized associational structure (Oteman et al, 2014). It is considered a new hybrid institution where societal roots of shared responsibility and environmental concerns are combined with market tasks such as profitability, security and access and governmental responsibilities (Oteman et al, 2014). This form of governance has already been seen in other sectors, for example, agricultural and housing associations (Oteman et al, 2014). In energy system, institutions are originally developed from community initiatives but are greatly institutionalized into a formal decision making body. It does not need to follow a full corporatist system, rather, it could also lead the system into the one in which state and civil society cooperate together to develop regulatory framework that brings about new modes of cooperation (Oteman et al, 2014).

These four institutional logics are not solely dominating one's energy sector, yet, countries show a various degree of combination of these systems. In Germany, (Oteman et al, 2014) aruge that the nation's energy transition shows the strongest trait of state-oriented system. As I described in the last two post, Germany's RE installation capacity started to increase rapidly once the FIT bill was passed through the Bundestag in 1990 and further accelerated in 2000 when Renewable Energy Act was introduced (Energy Transition, 2015). Until then, community initiatives were very limited because of the lack of knowledge, investor's confidence and funding.

Nonetheless, I think it is important to note that Germany's energy transition did not emerge out of the state. As explained in the earlier post, the key to the nation's oldest FIT legislation is the emergence of anti-nuclear sentiments in 70-80s (National Geographic, 2015). These local collective actions across the nation gradually led to the formation of Green Party, which contributed to introducing 'green' ideas to the Bundestag later on (National Geographic, 2015). This is also regarded as an example of the corporatist association order because the nationwide green movement resulted in the environmental associational structure, which then was formed into the Green Party that is now politically powerful in Germany today. Therefore, the emergence of Germany's energy transition was achieved in community-oriented system and was further developed through the state's intervention.

In the next post, I would like to discuss the future of Germany's energy transition. Any comments or questions are much appreciated!

Theoretical Understanding of Energy Transition in Germany Part 1

In the last post, I looked through the history of Germany's Energiewende (Energy Transition). Based upon the historical narratives, what I would like to do today is to make some literature reviews on community initiatives in renewable energy (RE) development.

First and foremost, let me clarify some basic terms. Community initiatives are defined as 'decentralized, non-governmental initiatives of local communities and citizens to promote the production of particular goods or services (in this case RE)' (Oteman et al, 2014). In Germany, such RE schemes were quickly introduced following the first FIT scheme in 1990 and further accelerated in 2000 when Renewable Energy Act was passed through the Bundestag (Energy Transition, 2015).

Photo.1. Wind turbines in Ockholm Schleswig-Holstein, near the planned start of the new high-voltage power line (The Gurdian, 2014)

In the study undertaken by Oteman et al, (2014), there are three major theoretical explanations about the emergence and opportunities for community initiatives; agency-oriented; structure approach; and biophysical conditions. They share some common understanding about RE development, however, their approach is slightly different from each other.

Firstly, agency-oriented approach focuses on different individual features such as detailed local knowledge, intrinsic motivation and leadership capabilities. It comprises of four sub-components; cultural capacity; organizational capacity; infrastructural capacity and personal capacity. Cultural capacity describes what is considered to be legitimate and socially accepted as sustainable objectives. These are inherently embedded in their community values, and examples include autarky, anti-capitalism, energy security and anti-nuclear sentiments (Oteman et al, 2014). Organizational capacity looks at the position of community RE initiatives within the wider local community. It determines how socio-politically powerful they can be to engage people or key stakeholders to make initiatives prosperous (Oteman et al, 2014). When it succeeds, it creates a sense of ownership and responsibility, reducing the effects of Not-In-My-Back-Yard. Infrastructural capacity looks at the provision of facilities by government or the market, such as grid access. Lastly, personal capacity focuses on resources of the individual memebers of an initiatives such as voluntary contributions, skills, knowledge and leadership qualities, values and enthusiasm (Oteman et al, 2014).

I think the theory is very useful when it comes to describing the characteristics of individual RE initiatives. For instance, Germany displays great cultural capacity of 'green' values, which has been exemplified in the demolition movement of nuclear power plants and fossil fuel-based energy system (National Geographic, 2015). However, it does not really explain 'WHY' different countries display distinct patterns of appearance of RE community initiatives and their degree of success.

Secondly, structural approach looks into community RE initiatives from three different attributes; socio-cultural; economic; and legal (Oteman et al, 2014). Socio-cultural subsystem describes the public perception of energy and the role of community in this and attitude towards experimenting and innovation. This is equivalent to the cultural capacity in the agency-oriented approach. Economic attribute, however, is a very different approach to the former. It essentially looks at the division & allocation of financial and other material resources among the actors or general economic climate (Oteman et al, 2014). This emphasizes the fact that whether an initiative is economically viable and successful is highly dependent on the expected profitability of the project.

Legal attribute refers to the formal legislation that directly favours RE, for example, Electricity Acts, grid access, degree of territorial functional decentralization, structure of the policy and procedures for collective decision-making. It is a critical part that both promote and restrain the development of RE. Arguably, Germany would not have been able to achieve the current levels of community RE without a series of law that favours their development (Nolden, 2013). I suppose it is because, in market economy, large utility companies can easily price out the small-scale community energy companies / associations through economies of scale. It is an example of oligopoly where a relatively small number of firms dominate the industry (Gutiérrez-Alcaraz and Sheblé, 2006). Therefore, there needs to be government's intervention in supply side if community-level energy companies want to enter the industry. What I think the structure approach is significant is that it can be used to compare and explain the patterns of RE development in different countries because of the quantitative economic and legal approaches.

Thirdly, biological conditions fundamentally look into the biological and physical availability of RE production (Oteman et al, 2014). This includes the annual sunlight hours and wind potential which determine the potential energy production. It also refers to the spatial planning of the project such as the degree of urbanization and remoteness of rural regions. These spatial layout is an important physical condition that influences local structure and agency characteristics of RE development. In Germany, for instance, the north is frequently characterized by high wind potential and therefore most wind turbines are found there. By contrast, the south has historically struggled with implementing RE despite some solar panels and community-level wind turbines being increasingly introduced. In fact, it is still heavily reliant upon nuclear power (The Guardian, 2014). Although some cities like Munich have adopted a strategic plan to produce wind energy in the North Sea and feed their electricity demand, known as Dantysk project, to me, the true 'local energy security' does not seem to be met. I guess they also need to develop locally-produced alternatives such as biogas, so that in case the energy transmission is to be shut down or politically targeted.

Among these three approaches, Oteman et al (2014) put a great emphasis on the structural characteristics of the energy sector to give the theoretical understanding of the occurrence and development of RE. They argue that governance of the energy sector is managed through the combination of the following four institutional logics; market-oriented system; state-oriented system; community-oriented system; and corporatist associational order (Oteman et al, 2014). These essentially form a set of interrelated incentives & constraints that influence agent's behaviour and strategies. Here, the extent to which the state, market and associations are complementary to community RE initiatives and offer them 'institutional space' is studied as 'institutional arrangements theory' (Oteman et al, 2014). Halls and Taylor (2006) defines it as 'the formal/informal procedures, routines, norms and conventions embedded in the organizational structure of the polity/political economy', which are reflected in the structure approach. In other words, it describes the degree of discrepancy freedom of community initiatives to decide autonomously about the design a project its contents' (Oteman et al, 2014).

Now, the question is which kind of institutional arrangements Germany has made over the last few decades to achieve the famous energy transition. Has it always been community-oriented or a mixture with the market-oriented system? In the next post, I will further look into the theoretical understanding of energy transition in Germany with a particular focus on this institutitonal arrangements theory. Any thoughts or questions are more than welcome as always. :)

What's All About Germany's Energiewende?

Photo.1. showing wind farms outside the Feldheim village during a visitors tour.

If you're engaged in or once dedicated to research in the field of energy policies, I guess you would almost certainly have heard of Germany's revolutionary movement called 'Energiewende'. The term represents the transition from a fossil fuel & nuclear-based sector towards a pro-renewable energy (RE) system (Oteman et al, 2014). As I quickly introduced in the last blog post, Germany now produces electricity from RE approximately by 27% this year, with half of them being privately owned by individuals or community cooperatives (National Geographic, 2015). Despite the country is ranked at the top in GHG emissions per capita in Europe, they are also the fastest in reducing their emissions, with an astonishing 27% decline since the 1990 level by 2012 (Figure.1). By 2020, they aim to further cut up to 40%, and by 2050, it is striving to achieve a 80% cut (Oteman et al, 2014). Note that, however, the graph below does not represent how much renewable energy has been introduced in the countries. France, for example, is far smaller in total emissions because of its reliance on nuclear power without much RE being installed.

Figure.1. A graph shows a shift in total emissions in some European countries from 1990 to 2012. Germany is one of the fastest, followed by the UK. (Source: National Geographic, 2015)

So, what distinguishes Germany from other European countries? Why have they been so successful in reducing GHGs emissions over the last few decades? These are some prominent questions I would like to address in the next few posts. 

To begin with, it would be helpful to explore some historical backgrounds of energiewende. The origin of the term traces back to 1980 when the German Oeko Institute published a study called 'Energiewende', which signifies the possibility of economic growth with less energy, therefore nuclear and petroleum can be demolished and replaced by renewable sources (Oeko Institute, 2015). Prior to this publication was a historical movement against the construction of a nuclear power plant in Wyhl, the south-west Germany (Energy Transition, 2015). Near the location is Freiberg where residents were first politically pressured by the authority saying blackouts would be highly likely in the case the plant wouldn't start operating. 

Despite the intimidation, local communities solidified to occupy the construction site and continuously demonstrated against their plan. In the end, the plan was abandoned - the first time ever the introduction of nuclear reactors was prevented in Germany (National Geographic, 2015). Now, Freiberg is known for its one of the highest per capita installed capacity in solar PV panels, with some 50 solar settlements which produce more energy than they consume (Rolf Disch, 2015). They are designed by a local architect Rolf Disch, who actively joined the Wyhl protests (Photo.2 & 3)

In fact, a series of anti-nuclear movement in 70-80s was not simply because of their concerns over safety. It was also about geopolitical tension to which Germany was once forced to be exposed in forefront geographically, namely the US and the Soviet superpowers. The US used to (and still today) hold their nuclear bombs in West Germany against the former, and that was what agitated against nuclear demolition nationwide. It is still an ongoing debate in the country as the recent decision to increase the US's atomic weapons in Germany in spite of the 2009 parliamentary decision to gradually withdraw them - completely against the will of the citizens (Washington's Blog, 2015).

The following was the emergence of the Germany's Green Party advocating for pacifism and opposition to nuclear power plant (National Geographic, 2015). In 1983, first Green representatives won the election for the Bundestag, Germany's national parliament. It was one of the socio-political milestone in Germany that has constituted what the country looks like today. After the 1986's Chernobyl disaster, their influence has become inevitable.

In 1990 when Germany became reunified after the Soviet collapse, a first feed-in tariff (FIT) bill was passed through the Bundestag (Energy Transition, 2015). However, it was not until 2000 when the system started to fully exert a potential force. Hans-Josef Fell (Photo.4), who has been one of the most influential Green Party politician was a key person. He used to be a member of the City Council in Hammelburg before he joined the Party, and helped the council pass an ordinance that ensures the municipal utility to guarantee the payment to any renewable energy producers to more than cover the installation costs therefore make a profit (Energy Transition, 2015). 'The payment had to be so high that investors could make a profit. We live in a market economy, after all', he said (National Geographic, 2015). This market-oriented theory is marked by a number of studies (Nolden, 2013Oteman et al, 2014) although the degree is highly dependent upon the nature of agency, institution and biophysical characteristics of countries (Oteman et al, 2014).

The success story of Hammelburg then led Fell to ride a Green wave and into the Bundestag where the Green formed a coalition with the Social Democrats (SPD). In 2000, he and Hermann Scheer (Photo.5), who is a prominent supporter for solar energy within the SPP, crafted a law called 'Renewable Energy Act' (Energy Transition, 2015). There are mainly two principles of the Act, first to mandate the FIT payment rates to be based upon the cost of investment instead of the retail rate (therefore above the market price), and second, to prioritize the renewable energy to be fed into a general grid with the guaranteed rate for 20 years.

This has made a number of individuals, communities confident enough to embark on their own renewable energy projects because they can plan well how long it would take to cover the cost and start making a profit. It also encourages active community investments on such projects because of the high creditability that the government provides under the formal legislation. It has been further accelerated by a traditional system of the state-owned bank KfW with €100 billion credit loans available between 2012 - 2017. These are some of the examples of structure-oriented force that explains the emergence of community initiatives (Oteman et al, 2014). As a result, there have been significant rises in many renewable energy production since 2000. For example, wind power generation almost doubled from 2000 and 2004 and still keeps growing until today (Figure.2).

Nevertheless, the country is not free of challenges. Firstly, since the 2011 Fukushima disaster, public opinion has been against nuclear power, which forced the government to call for a demolition plan of all their 17 plants by 2020 (Nolden, 2013). This raises a question about how the country would replace the supposedly 'green' energy, climate change-wise. Will they be successful in covering the nuclear generation by all the natural, clean force of energy? Or will they increase their import of nuclear / fossil fuel-based energy from nearby countries? There're also concerns about the over-exploitation of lignite (Photo.6), which is naturally rich in Germany, generating 26% of the total energy in the country (National Geographic, 2015). With hard coal mostly imported from outside (18%), the country still relies its energy source on coals by more than 40%. This also causes a massive destruction of Germany's beautiful forests through acid rain or mining activity itself.

Among these is traditional 'Big Four' (E.on, EnBW, RWE, Vattenfall), which have long been politically influential in delaying the energy transformation through lobbying (National Geographic, 2015). Today, they seem to rapidly increase the investment on renewable energy particularly offshore wind, yet, this could in turn price out small-scale community RE associations, which some critics say the another form of lobbying the government to favour big utilities in expanding RE. So, what would that mean to Germany's energy sector if community projects will not manage to increase in number and scale? 

From climate change perspectives, Germany also faces some other challenges regarding two major sources of GHGs emissions - transport (17% of GHGs) and heating system (30%) (National Geographic, 2015). The latter is to some extent locally provided by bio-gas through manure fermenter and direct heating from the sun (Oteman et al, 2014). However, the scale is very limited spatially and it cannot be expanded like a central energy system where electricity / gases are managed and provided by big utility companies. In addition, because of the biophysical characteristics of renewable energy, it's better to produce it where consumed. This is particularly critical when it comes to transmitting energy produced in the windy North to the more industrialized South where far more energy is demanded. The government and utility companies once proposed to build a high-voltage direct current (HVDC) such as the one connecting Bremen and Bavarian (Figure.3). 


Photo.6. showing a mining site for lignite at Vattenfall



Figure.3. A map showing the HVDC networks that connect the North Germany and Bavaria (Source: National Geographic, 2015).

Nonetheless, controversies still remain high because some landowners have rejected it as unnatural disturbance spoiling the natural beauty in their land. Also, the transmission loss of energy (mainly through heat) could be another potential limitation that questions the effectiveness of such transfer projects. Therefore, I think that they need to further expand the existing local-based, decentralized energy system not only to achieve the Germany's ambitious GHGs emissions cut but also to ensure local energy security that helps improve the national energy security as a whole. 

Here, I'm wondering how community energy production and big utility companies can cooperate, or compete well? Of course, what is the best way to provide energy to people is probably different from place to place, depending on the nature of agency, institution, and biophysical conditions as mentioned earlier. In the upcoming posts, I will try to address the questions raised above including the primary ones I mentioned at the beginning (perhaps one by one since there're too many). If you have any thoughts or questions, please feel free to share in comment. :)
