Implementing Energy-as a Common approach in the revitalization of shrinking cities

L'énergie comme bien commun dans la revitalisation des villes en déclin
Simone Di Pietro


Les nouvelles tentatives de mise en œuvre de transformations vertes de l’économie visant la durabilité coexistent avec le passage de l’ère fordiste à l’ère post-fordiste, contribuant à créer de profondes transformations territoriales dans le monde entier. Bien que la crise économique actuelle ralentisse le processus de transition énergétique au niveau mondial, la définition de la future structure économique des territoires sera strictement liée aux effets spatiaux des transitions énergétiques et à leurs processus intensifs d’utilisation des sols, étant donné la faible puissance des sources d’énergie renouvelables. Les centres urbains sont les lieux où ces changements se reflètent le plus rapidement et le plus clairement, car ils sont les centres des principales activités économiques. À cet égard, les zones urbaines qui connaissent une marginalisation économique progressive et une dépopulation conséquente, sont confrontées à des problèmes de durabilité concernant l’utilisation de l’énergie et la maintenance des infrastructures existantes. Dans le but de clarifier le rôle des villes en décroissance dans ces transformations, une contribution théorique est présentée en considérant différentes approches de la co-production des processus de transition énergétique dans ces villes.

The challenge of greening energy supply in densification demand processes

1In the increasingly unstable global context also given by the current COVID-19 pandemic, market-centred development scenarios seem to project civilization towards a fortress world in which elites work to impose an authoritarian order to establish control over resources, where even the concept of sustainability is modelled at will in order to legitimize business as usual (Raskin et al., 2010). In this context of growing uncertainty, the local response acquires greater significance in defining the future of the territories, therefore urban shrinkage contexts already characterized by a certain level of organizational capacity can offer a good ground for innovative development strategies that fit into the postmodern crisis of globalization processes.

2According to ecological criticism (Martinez Alier, 2002), the economic system is based on the continuous externalization of environmental costs, which are shifted to higher space-time scales and are difficult to quantify. In this context, rural areas are seen with greater potential to return to sustainable development models based on organic production and the use of local resources, while large cities are seen by definition as unsustainable due to too high levels of densification of demand.

3The world economy is increasingly based on the use of resources found in the environment (Giljum and Eisenmenger, 2004), that are extracted in a heterogeneous way on the planet, in turn, creating heterogeneous effects on the availability, quality, demand and supply of energy throughout the world. Considering the physical aspects and in terms of environmental impacts (Schutz et al., 2004), the so-called dematerialization (the use of a lower flow of materials and energy per unit of production) of the economies of the North is carried out, also based on a transfer from the North to the South of the intensive production of natural resources.

4On the demand side, higher levels of energy consumption per capita usually correspond to higher GDP per capita (Csereklyeietal, 2016), reflecting the disparities in the development processes, so that, while the biggest concern in northern countries is securing resources to ensure thermal comfort, many global southern countries face extreme energy poverty situations such as a lack of fossil fuel for cooking (Day et al., 2016), especially in rural areas. Another similar issue is the quality of the fuels used, where this is significantly lower in poor countries causing high pollution rates with harmful effects on health.

5A growing focus on how to solve energy problems is centred in cities, since they already are currently responsible for two thirds of global primary energy demand, and this proportion is growing: considering urbanization processes towards cities with a minimum population of 300,000 inhabitants, in 2050 around 68% of the world population will be living in cities, compared to the current 55% (United Nations, 2018). The urbanization process is tightly connected with the heterogenous demographic growth accompanied by the lack of measures in spatial planning: while in countries of low fertility in Europe and Asia, policies of redistribution of the population are promoted, increase in urbanization will be concentrated above all in developing countries, with India, China and Nigeria, which will make the main contribution.

6In this context, a sustainable spatial organization of social activities without the use of fossil fuels or nuclear energy requires enormous infrastructure and sociodemographic changes to reduce energy demand and adapt it to the renewable energy resources available in the territory (Ariza-Montobbio et al., 2014). The achievement of these objectives will inevitably have to be based on strong social and structural changes, as well as a substantial re-planning of policies, including redistribution of resources and knowledge-based techniques.


7This article uses a descriptive approach to discuss the role of shrinking cities within the new geographies produced by economic and energy transitions related to post-Fordist transformations and the advancements in the use of renewable energy sources. The methodology is based on a review of the literature and interviews realised with experts. The work is oriented to provide a theoretical contribution regarding the potential of the energy transition to improve liveability in increasingly marginal urban areas, discussing the possible benefits provided by a local management of energy transitions, through bottom up governance systems driven by principles of energy democracy.

State of the Art

Shrinking Cities within the new geographies of post-Fordist and energy transitions

8If the urban society was historically conceived in opposition to the rural society (Castells, 1971), the new transformations given by the arrival of new ruralities on the one hand and shrinking cities on the other, serve to create bridges between the two. Within the dichotomy between rural and urban areas are located shrinking cities, or urban centres progressively marginalized in the economic system and therefore with a possible motivation to undertake new paths aimed at sustainability and endogenous development.

9The most recognized definition sees the shrinking city as “a densely populated urban area that has on the one hand faced a population loss in large parts of it (for at least 5 years, more than 0.15% annually), and is on the other hand undergoing economic transformation with some symptoms of a structural crisis” (Wiechman, 2007).

10In the literature, different aspects related to sustainability problems in shrinking cities are emphasized. Whether shrinking cities are associated with more or less carbon emission is inconclusive, empirical evidence shows that shrinking cities tend to be less energy efficient (Liu et al., 2020) and less capable of mitigating CO2 than growing cities (Xiao et al., 2019). The emerging crises in shrinking cities can be seen as opportunities with possible new resources arising (for example vacant spaces) for urban planning aimed at improving liveability and sustainability (Pallagst et al., 2017, 2019).

11Cases of shrinking cities are described negatively when, rejecting the context of declining population size, sparse urban growth continues to be planned, as in the case of Ostrava in the Czech Republic, where long term unsustainability paths are being created (Slach et al., 2019).

12On the other side, approaches to the production of renewable energy or the implementation of more energy-efficient built environment can be implemented in shrinking cities, benefitting themselves of national frameworks, as it is in the cases of Herne (Förch, Pallagst, 2019) and Gelsenkirchen (Jung et al., 2010) in the Coal Mine German Region, and Vitry le François (Béal et al., 2019) in the French region of Marne, whose energy initiatives were applied in the context of the German Energiewende and the French Territoires á energie positive national programs.

13The environmental problems of shrinking cities are a direct consequence of their increasingly marginal economic situation. Shrinking cities are commonly seen as the sign of a symptom, or the “canary in the coal mine” (Audirac et al., 2010) of the global economic transformations, especially characterised by the post-Fordist transitions. The phenomenon of urban shrinking is considered as a socio-spatial aspect of the global economic system that tends to concentrate capital on the basis of the comparative advantages associated with the territories, modifying the functions for which they are intended. Silverman (2018) adapt the economic theory of dependency to the urban dynamics, where socio-spatial realities of shrinking cities are conceptualized within the economically peripheral regions, so that shrinking cities should be seen as the counterpart to the accumulation of wealth, capital, knowledge and infrastructure in global or metropolitan cities. In this sense, the global-periphery relations between the North and the South within the World Economy can be introduced in order to understand the economic relations between global and peripheral cities, where these last are situated in a subordinate situation, representing places of dispossession of the resources necessary to sustain the constant growth in global cities. This situation would be reproduced thanks to a colonized mindset and subconscious processes that would not allow local actors to act in function of a true local endogenous development. In other words, population decline affects not only the hardware, but also the software and mindware of an area, it means beyond the physical infrastructure, the norms and values of local actors, in turn connected to the external representation of their territory (Hospers, 2012). This could be the reason why urban shrinking processes are often treated as a taboo by municipal administrations (Pallagst et al., 2017), evidencing the gap with the academic literature who seeks to interpret this phenomenon as a possibility for planning paradigms, systems, development strategies or alternative cultures (Haase, Rink, 2012). Thus, as in dependency theory, the limited capacity to meet local demand and solve local problems in shrinking cities produces an increased dependence on external resources.

14Urban shrinkage understanding as peripheralization process who´s also discussed by Lang (2012) in the context of east Germany, is strongly related to flow and capital accumulation that tend to produce temporary “fixes” in space and time (Harvey 2006; Smith, 2010) and geographical inequalities (Großman et al., 2013).

15Spatial effects in urban areas are closely linked to the geography of production: in global growth, we observe a glocalization of production driven by leading industries (high technology, aerospace, electronics, financial) that are selectively localized depending on the relative global and regional competitive advantages (Audirac et al., 2012), so that in post Fordist transitions the new industrial production coexist with declining Fordist industrial districts, contributing to the generation of new crises in peripheral spaces. The most important sectors of the “new post-industrial economy” include professional, scientific and technical services, information, finance and insurance, real estate and rentals, arts, entertainment and recreation, business administration, educational services, health care and social assistance (Sassen, 2001). As well as migration and urban shrinkage phenomena increase, especially in countries of the global North, the impact of globalisation on the suburbs of the global South is contributing to the expansion of squatter settlements (Audirac et al., 2012).

16Replacing fossil fuels with renewable energies means mobilizing resources closer to consumers, but the potential for exploitation of renewable sources is also heterogeneous, depending on the morphology of the territory, the climatic conditions and the land use applied in it; whereby rural areas are also seen as green energy exporters to meet urban demand. Thus, new relationships arise between rural and urban areas, highlands with potentially more intense renewable energy resources and lowlands, as well as new intermediaries between production and consumption in urban areas (Balaye et al., 2018). This phenomenon is involved in the creation of the so called “new ruralities”, rural areas that are assuming the characteristics of urban centres and peri-urban areas conserving rural characteristics.

17On the demand side, in recent years, a fairly broad consensus has been established on the importance of promoting urban processes in a logic of compacting settlements, in order to maximize the use of urban land. Planning visions such as polycentric urban form and compact cities are often regarded as ideal-typical urban patterns and associated with environmental sustainability; these directives are also presented in the UN Habitat Urban Agenda (2016).

18Since the forms of urban settlements have a clear relationship with the use of energy in buildings (Mulligan, 2014), the construction of vertical buildings for multi-family dwellings makes it possible to contain per capita energy consumption, even if this logic supports the dynamics of centralized control in energy generation, by reducing the interurban potential of energy generation and the potential for bottom-up governance.

19Different architectural geometries and their positioning affect the use of energy, affecting the potential of passive zones, the implementation of technologies for the production of renewable energy, and contribution to the urban heat islands effect. Maximizing the use of daily light and natural ventilation by increasing the size of the windows or taking advantage of the solar heat thanks to a good positioning of the facades, are some of the measures that contribute to energy efficiency through planning (Mulligan, 2014). In this sense, the reduction of urban densities could have positive effects if the equilibrium point is determined at which it is possible to increase the potential for interurban energy generation in combination with the use of passive areas by new or undergoing building rehabilitation.

20With the aim of harmonizing energy demand, the dynamics of urban change must be studied through the analysis of the construction, demolition or adaptation of new buildings, between other, considering large or medium conversion projects for the re-use of abandoned infrastructures. The presence of vacant space or vast low-cost wastelands, could represent key locations for distributed energy generation in shrinking cities. These are usually characterized by the presence of uninhabited or abandoned houses and in some of these cases, demolitions or retrofits of the infrastructure are carried out. The demolitions produce vacant spaces that can then be used for common uses, while, in the case of retrofits, these should be carried out in order to improve energy efficiency, under the concept of passive zones and bio climatic designs.

21Energy problems in urban declining contexts are discussed by Hornebeck and Schwarz (2009), identifying a strong difference between the declining cities of Europe and North America: being the energy deficit much more pronounced in Europe, it is more likely that policies may redirect towards promoting the distribution of energy demand than in the United States, where, being the energy gaps much less common, cities that have lost population and industries could have a power generation capacity that exceeds demand. In order to cut the costs of maintaining the overcapacity of the energy infrastructure in shrinking cities, Hornebeck and Schwarz (2009) propose three alternatives: eliminating part of the energy infrastructure, reducing the costs of public lighting, and increasing decentralised energy generation systems from renewable sources. More than that, a balance that guarantees efficiency in consumption can be pursued by compacting the settlements, minimizing fragmentation and the use of non-productive vacant spaces that, if neglected, run the risk of devaluing the rest of the territory (Newman, Kim, 2017). New construction techniques may be implemented considering the concepts of passive areas and deploying potential for distributed renewable energy generation, minimizing the effect of urban heat islands by understanding the desirable levels of urban density according to the climatic characteristics of the territory. The latter can vary considerably depending on the uses of the buildings (housing, commerce, industry, services) and the geographical location (for example, temperate or tropical climates). This approach aims to guarantee greater energy efficiency, increasing social interaction and reducing devaluation linked to architectural deterioration. Increasing interactions can have positive effects on improving social capital and increasing organisational capacity, which can in turn bring new innovations of an economic or social nature, given the increased complexity of the urban ecosystem through increased exchanges and contacts (Rueda, 1998).

22However, successful interventions will depend on the numerous dynamics resulting from the constant interaction between actors who establish and modify the structure and morphology of settlements (Sánchez, 2013). Uncoordinated processes of compaction of the city run the risk of creating a new dynamic of polarization, inequality (Buhnik, 2017; Fol, 2012) or urban gentrification (Audirac et al., 2012), therefore, municipalities should implement the best urban planning alternatives in order to minimize negative social effects by pursuing a balance between local energy supply and demand.

Discussion and results

Strategies of energy transition in shrinking cities

23The urban shrinkage phenomenon should be observed as a circular process (Hoekveld, 2012) closely connected with the local context of the region in which it occurs, and the role it plays as a peripheral node into the information network society (Castells, 2004).

24The phenomenon of urban shrinking can be very varied and take on different types: Oswalt and Rienits (2007) identified no fewer than twenty-one causes of shrinkage across the world, while Branislav et al. (2019) distinguish the different types of shrinking cities according to the economic-political causes, the character of shrinkage duration, shrinkage timeline, seriousness of shrinkage process, spatial level of shrinkage and size of shrinking city.

25Identifying the type of a shrinking city is essential to define the interventions to be applied in view of sustainability. Depending on the type of shrinking city and consequently on the type of resources available, it is possible to identify several strategies that can enable shrinking cities to play an important role in energy transition processes.

26These can be summarised into three categories: research and development in green technologies; energy transition plans with an integral approach through public-private partnerships; local energy production through community cooperatives or individual prosumers.

27While the first two assume top-down management, the third strategy involves bottom-up mechanisms facilitated by the inclusion of appropriate rules.

28Technology production strategy is a potentially successful strategy depending on the ability to attract investments to create innovation in highly advanced and competitive sectors.

  • 1 Interview with Projektmanager Wissenschaftspark Gelsenkirchen GmbH, October 14th, 2020.

29In Gelsenkirchen, as part of the solar city strategy aimed at redeveloping the image of the city for decades associated with the negative effects of contamination from the coal industry, energy transition is been boosted through the establishment of a Science Park for the research, development and marketing of renewable energies (Jung et al., 2010). Despite Science Park Gelsenkirchen has currently lost its role as a photovoltaic technology manufacturing cluster as a result of the German solar industry’s lack of competitiveness compared to the efficiency standards achieved by the Asian market1, it continues to provide jobs for more than 400 employees engaged in R&D, marketing and engineering education, through a private public administration, where the ownership shares are divided between the city of Gelsenkirchen and the Gelsenkirchener Gemeinnützige Wohnungsbaugesellschaft GmbH. The experience of Gelsenkirchen demonstrates that the path of renewable energy technology production is difficult to create, especially in shrinking cities such as peripheral areas with low economic diversification, but it can still be a good strategy where there are opportunities to attract a critical mass of skilled workers in the energy industry, especially trained in green technologies. The aim would be to compete in the globalised market with the technologies currently at the forefront of the Asian and North American markets.

30Energy transition plans with an integral approach through public-private partnerships is another of the strategies applied in shrinking cities and the degree of transition can be more or less pronounced. Examples include the same city of Gelsenkirchen but also Herne, both of which are located in Westphalia, in the so-called Coal Mine region of Germany. A more industrial ecological approach can be found in the case of Dunkerque in France, but the case that adopts a more advanced integral approach is Vitry le Francois, a shrinking city in the Marne region of France.

31The cities of Gelsenkirchen and Herne are part of the German Ruhr region in the state of North Rhine Westphalia, being part of the called European Coal Mine region. Both these cities have faced economic transition processes due to the decommissioning of coal mines, deciding to invest in the energy transition aimed at clean energy. In Gelsenkirchen, the “Gelsenkirchen-Bismark Solar Housing Estate” project was completed in 2000s, a real estate project with low energy consumption and solar architecture, for a neighborhood of more than 100 homes (Jung et al., 2010). A very similar project was also established in the nearby city of Herne, where as part of the conversion process of the old mines the Mont-Cenis Energy Park was created, consisting of a cogeneration plant with 3,200 integrated photovoltaic modules, energy storage infrastructure and one of the largest rooftops solar photovoltaic production plants in the world with the power of 1 MW, feeding a training academy which acts as a city social centre and district administration of the city of Herne (Förch, Pallagst, 2019).

32An industrial ecology approach was adopted in the shrinking city of Dunkerque in France, where a new combined cycle power station with a power capacity of 790 MW, replaced the old thermal power station managed by EDF and at the end of its life cycle (Beaurain, Chembessi, 2019).

33The integral energy transition approach can be found in the shrinking city of Vitry le François. Vitry le François is a town of around 12,000 residents situated in the Champagne region of eastern France. In this formerly industrial area, demographic shrinkage above all concerns the core town of Vitry-le-François, where the population fell by 32% between 1975 and 2014 (Béal et al., 2019). This process is linked to the strong migration originating from the deindustrialisation typical of the post-Fordist transition and only partially offset by the creation of new jobs in the third sector (Miot, Rousseau, 2017). In particular, from the 1990s a demolition to rebuild strategy is ongoing through an urban renewal project resulting of an agreement between the local administration and the single social landlord «Vitry Habitat», owner of 54% of housing stock. At the same time, a series of 33 projects that include biomass heating system, industrial ecology, renewable energy production, production of hydrogen as a transport fuel, energy efficiency and waste management, are being implemented also thanks to the partnership established with the private sector, in particular with the French energy company Electricité De France (EDF), which can use this territory as an experimental laboratory for future large-scale changes with a view to sustainable development.

34Local energy production through community cooperatives or individual prosumers can be seen as a favourable strategy both with a view to achieving energy self-sufficiency and to receive profitable revenues from the sale of surplus energy to the national grid, if the appropriate incentives and legal frameworks are in place. On the other hand, new prosumer business models are emerging in a post-subsidy era (Brown et al., 2019), to compete with fossil fuels and adapt to progressively less generous national subsidy schemes.

35According to the REScoop (Renewable Energy Sources Cooperative) network, an increasing number of over 1.900 energy cooperatives are already operating across Europe.

36This business scheme, based on the creation of community businesses managed through a horizontal type of governance, seems to be particularly advantageous as a development and community benefit strategy in small and declining towns. Smaller shrinking cities seems to be even more prone to long term and extreme shrinkage (Restrepo et al., 2017), for this reason the system of energy cooperatives can be an alternative way of keeping these centres alive, creating new opportunities for subsistence.

37An example of this is the small town of Melpignano, located in the southern area of ​​the region Apulia in Italy, a region characterized by a substantial demographic stability for many years and with projections of a strong demographic decrease of 26% in the next fifty years, according to the Regional Agency for Technology and Innovation (ARTI, 2019).

38Melpignano is one of the small towns in the south of Italy characterized by a non-specialized primary economy, a poor exploitation of resources and/or potentials, social and economic inactivity, conservative and traditional territorial organization and ways of life: these features are common to a large part of the thick Italian settlement plot, rich in small-sized centers (with less of 5,000 inhabitants), but which are showing a growing openness to local development policies in search of sustainability, looking with hope beyond the decline and change tack, without shutting off from the rest of the world (Rinella, 2019).

39Melpignano registered 2.211 inhabitants in 2019, but the demographic trend line shows that, even if temporarily, depopulation occurs in a cyclical way. Regarding the economy, the local system of Melpignano, as well as that of the surrounding municipalities, is classified by ISTAT as “system without specialization”. The economy of Melpignano is based on agricultural production for the production of extra virgin olive oil and wine, as well as on tourism generated by the annual event of the final concert of the Taranta music festival, organized every month of August.

40The case of Melpignano is one of the emerging energy communities in Italy that are benefiting from national support to renewable energy, which are progressively shaping the Community Energy sector in Italy (Candelise, Ruggieri, 2020). The Melpignano Cooperative Community was created in 2011 by an agreement of 71 founding members (then reached 127), under Cooperative Community scheme. Similar to the formula of the Social Cooperative, the Cooperative Community institution is regulated in the Apulian regional law n. 23/2014, with the aim of pursuing the development of the reference community. The initiative was born from the collaboration between Legacoop and the local administration, with the aim of managing a solar energy production network through photovoltaic panels placed on the roofs of public or private buildings. According with his statute, the community cooperative of Melpignano has the responsibility to install the systems and provide for their maintenance, managing the production of energy with metering appropriate to the needs of users and reselling the surplus on the market (Tricarico, 2015). The construction of the decentralised energy system in Melpignano worked thanks to the presence of more extensive building typologies and therefore of numerous roof owners, who transferred their use to the cooperative for 20 years, receiving free energy. The different members of the cooperative join the company voluntarily, based on the different tasks performed: self-employed members, who bring technical skills and take care of the construction of the plants; user members, who are distinguished in “host” members, that is citizens who want to host a photovoltaic system on their roof and “simple” members, who join the project with a membership fee in order to benefit from electricity at favourable conditions; “subsidizing” members, that is those who decide to invest in the project by bringing capital for its realization. The use of profits is established by the shareholders and can be intended for interventions aimed at promoting the regeneration of the urban space: interventions to improve public green areas, refurbishment of road surfaces, school bus services, school canteens. One of the ways to reinvest profits was the installation of a water dispenser in order to supply chilled mineral water at 5 cents per liter, with the aim of generating environmental and economic savings in terms of plastic bottles not produced and of quantities of CO2 not emitted into the atmosphere.

Greening/Rightsizing shrinking cities through energy as a common approach

41Referred to the contexts of urban shrinkage, the term ‘greening’ is used as a strategic approach that aims to develop green infrastructure along with supporting environmentally and socially acceptable practices at the national, state, regional, and local levels (Pallagst et al., 2017). Operating a good greening process should produce convergence between the interests of environmental conservation typically of the national level, with the interests of social and economic benefits at the local level.

42While there is a general consensus around the pillar of greening shrinking cities, less emphasis is given to the objectives of regrowing shrinking cities under the consideration that the main objectives should instead be to establish a more liveable, less chaotic urban environment, reducing the stress elements typical of large metropolises. In this sense, the new conditions can be exploited to improve liveability, if considering that size and density are the strongest drivers of unhappiness in the city (Okulicz-Kozaryn, Mazelis, 2018), shrinkage leading to a smaller, less dense environment, should make residents happier (Hartt, 2019). From a theoretical point of view, “the contrary of shrinkage is not growth but adaptability” (Brandstetter et al., 2005), switching from the slogan “smart growth” to that of “shrink smart” (Pallagst et al., 2009), that is achieved by directing planning towards efficiency and sustainability.

43The two pillars of greening and rightsizing shrinking cities can serve as concepts to inspire changes in shrinking cities, where energy transitions with horizontal governance and benefit sharing fall under both of these pillars. The notion of rightsizing should refer to the process of guaranteeing the right to the city for all inhabitants without distinction of any kind; it is therefore closely dependent on the type of new economic opportunities and, in the case of energy transition, on the distribution of benefits at the local level and reinvestment to improve the quality of urban life in shrinking cities. In the absence of this focus that considers advantages and disadvantages on a case-by-case basis, speculative mechanisms could be encouraged, turning out into an attempt to reset growth by converting the most expensive parts of the territorial social economy into a new investment opportunity (Hackworth, 2015). Under bad management or government, interventions of energy transition can be experienced as trojan horses of capitalist accumulation, as is often the case in the global South, where their neo-colonial characterisation often create new socio-environmental conflicts (Siamanta, Dunlap 2019; Sánchez De Jaegher, 2018). Therefore, the concept of rightsizing is closely linked to that of environmental justice, since the growing interconnectivity has to be recognized between the types of resources (energy, materials, food, water and land), it means between eco and human systems. Energy system has also had a significant role in producing conditions of economic and social inequality (Martinez, 2017), for this reason, energy transition initiatives should be implemented with adequate governance and business models, with the aim of pursuing development that includes environmental justice, since even embracing urban green as a universal amenity may be criticized if traditionally marginalized groups (e.g., low economic class, people of color, low educational attainment) will have less access to amenities and less power in the processes determining their distribution (Schwarz et al., 2018).

44Urban greening pillar has gained significance, achieving the status of a tool with strategic urban development potential (Reimer, Othengrafen, & Rusche, 2015). Greening shrinking cities should primarily focus on the re-use of vacant spaces in order to embrace the new smaller footprints (Pallagst et al., 2017). The rationale behind this practice is that the abandonment of vacant lands reproduces the devaluation of the territory including the properties of the inhabitants, while the re-use of them can constitute a resource for the economic recovery and the revitalization of the territory. According to Newman et al. (2018), land transformation prediction models can be a useful tool for predict spatial vacancies in shrinking cities. Vacant lands represent a shared social responsibility (Dubeaux, Cunningham, 2017) for the community and at the same time a resource, which can be seen as a common good. On the other hand, space has become an important resource to allow a clean energy transition in modern society, due to the low energy intensity of renewable resources compared to fossil fuels. In this sense, a critique to energy transition made by Shellenberger (2019) argues the “poor physics” behind renewable energy sources, so for example “solar farms take 450 times more land than nuclear plants, and wind farms take 700 times more land than natural gas wells, to produce the same amount of energy”, would explain that renewable energies are not suitable for the electrification of modern society but rather, would have the aim of transforming back society into agricultural one. However, this criticism does not consider the inherent unsustainability of modern society based on the use of fossil fuels, so it is clear that in terms of energy use, a middle way between modern society and agricultural society must be sought from an evolutionary perspective.

45This argument leads to deepening the discourse on energy localism and democracy, as a strategy for sustainability and community development. Recognizing the high degree of complexity present in this issue, a holistic and integrated approach must be applied.

46Energy Democracy can be understood as a contemporary expression of the political movements of the 1970s and 1980s characterized by anti-nuclear activists and concerns about the geopolitical instability created by the hoarding of fossil fuels (Burke, Stephens, 2018).

47Since the crisis of the Fordist model, the local has been rediscovered in the 1970s and 1980s, leading to the emergence of alternative formulas for development, such as: self-development, eco-development, endogenous development, eco-centric development, integrated development, human-scale development, etc. All these terms refer to the development of local society. Local society is defined as “a human group that inhabits the same territory, shares identity traits and common problems” (Arocena, 1995). The energy democracy movement promotes the transition to a new economic model based on the three main aspects of energy production: its relationship to the environment, social justice and a new economy characterized by community-based development, fair forms of production, socialized capital, ecological use of natural resources and sustainable economic relations (Fairchild, Al Weinrub, 2017). Like governance, socio-technical systems can be understood as either strengthening or weakening democracy, so that societies face a choice between authoritarian or democratic techniques (Mumford, 1934). In this sense, Hall & Klitgaard (2012) argue that “When the only energy source harnessed was solar, economic and political power tended to be distributed, whereas, with the introduction of the use of fossil fuels, which are concentrated energy, economic and political powers also became concentrated”.

48As a low CO2-emitting energy system is the result of the relationship between actors making decisions in a territory composed of natural, technological, economic, legislative, social and cultural systems (Balest et al., 2019), the relationship between actors is fundamental to developing effective energy planning and the inhabitants play a role in the implementation of decentralized energy systems. The collaborative planning approach plays a key role in developing the local civic capacities needed in the adoption of innovative policies. Population size as well as the presence of national environmental networks have strong influence on the adoption of environmental policies to address climate change, and the establishment of climate planning goals are also indicators associated with the adoption of local clean energy policies (Pitt, Basset, 2014).

49Citizen participation or civic engagement are intimately linked to the identification of people with their community and consequently with place attachment. They can be a keep factors for shrinking cities: residents who are committed to their community are less likely to move out (Hospers, 2012). Beyond this, ground-up, cooperative and participatory solutions are more sustainable in the long run (Dewar, Thomas, 2013).

50In the era of globalisation, “the problems of maintenance, production and distribution of the commons in the ecological and socio-economic framework will become increasingly central” (Negri, Hardt, 2009). Despite the problem or “tragedy” (Hardin, 1968) of the commons will always have to deal with free riders and other opportunistic behaviors, Ostrom (1975) justifies the choice of cooperation as a strategy to maintain long-term gains.

51According to several authors, responses to shrinkage must start from the bottom up, embedded in local cultures, institutional configurations and opportunities for change to be effective (Hoekveld, 2012).

52This is based on an interdisciplinary approach combining engineering sciences with social and spatial sciences, to jointly build an inclusive territorialisation of the energy transition, leading to energy justice (Henriot et al., 2019).

53According to Foldvary (2001), the association of community members for the provision of services, including through the creation of a governmental body, can be conceived as an evolutionary process while the transfer of political authority, property and programs from a higher level to a lower level of governance is to be considered as a devolution process.

54Fernández et al. (2014) criticize the permanent delegation and corporatism of modern individualist society, while proposing participatory methodologies as a way to build a new society based on citizen participation, solidarity, co-responsibility and direct democracy, through the integral, multidisciplinary and interdisciplinary action.

55Sustainability is not justified by some macro-economic figures, which some experts can give, but by the criteria and indicators of quality of life that each community wants to build at all times, thus marking the pace of their lifestyle (Fernández et al., 2014).

56Energy as a common approach must be supported by a technical, social and political aspect. Like all common goods, these must be subject to rules to plan their exploitation. For this reason, communicative planning is an essential aspect. Shrinking cities are laboratories not only for actual urban developments, but for democracy on a local scale (Haase, Rink, 2012). Energy transition that considers renewable energy production as an asset to be managed for community benefits relates co-production with the other levels of service provision: co-governance and co-management (Pestoff, 2012). Co-governance is about actors from different organizations and sectors coming together to determine policy priorities and to translate these into strategic plans. Co-management refers to a situation where representatives from different organizations work alongside each other to manage the delivery of a service. Co-production is an arrangement where citizens produce, at least in part, the services they use.


57The new European green deal has the objective of achieving climate neutrality by 2050, implying major new investments in the energy transition sector, with the probable creation of numerous incentives that should be redistributed throughout the territory by the European institutions, as is already happening through DG for Regional and Urban policy, and which could also be used for the revitalisation of shrinking cities.

58The adoption of decentralized energy systems is not sufficient by itself to indicate a high degree of energy transition in the urban context. This element must be combined with others, such as the adoption of measures for the efficiency in consumption and policies for the progressive abandonment of fossil fuels. In other words, the degree of energy transition has to do with the analysis of urban metabolism.

59The common characteristics of many shrinking cities such as the overcapacity of energy infrastructure and the presence of vacant spaces can favor energy transitions aimed at reduction in maintenance, transport and production energy costs.

60Creating a horizontal governance capable of understanding energy as a common good implies a considerable community effort facilitated by the institutions but put into practice by citizens through models such as the cooperative community of Melpignano.

61Top down business models linked to energy transitions still prevail, being managed and financed by institutions and implemented through the work of specialized companies such as in the cases of Gelsenkirchen, Herne and Vitry le François. In most cases, the local community benefits from these projects while in others socio-environmental conflicts could arise. Colonized imaginaries may represent obstacles for creating new innovative experiences of local endogenous development through laboratories of democracy in shrinking cities.

62Finally, the type of feasible energy transitions in shrinkage cities must be established on various aspects, as the size of cities, current state of the infrastructures, presence of vacant nonproductive spaces, socio-demographic and political characteristics of the population.

63The energy cooperative model based on bottom-up rationale is extremely beneficial in the case of small municipalities such as Melpignano, while larger-scale energy transition systems require coordination mechanisms and institutional partnerships in agreement with the greater quantities of investments necessary to convert urban infrastructure.
