This chapter reviews the spatial and social differences that underpin existing and past patterns of energy poverty in Europe. This is achieved via exploration of scientific research focused on the topic, either as a central object of enquiry or as part of wider investigations in which the issue is brought up as a relevant factor. Special attention is paid to the large-scale geographic variation of energy poverty in Europe, as well as the manner in which this diversity is subsequently reflected at the level of nations, regions and particular demographic groups. I also discuss the driving forces of energy poverty within particular spatial contexts; and in an effort to move beyond the traditional geographic focus of energy poverty research—the UK and Ireland—the chapter first systematically overviews the development of a debate focusing on different parts of the European continent and its immediate neighbourhood. I then review evidence about patterns of energy poverty at a variety of spatial scales.

As was noted earlier in the book, the majority of evidence about the underlying causes of energy poverty has been generated by studies undertaken in the UK and the Republic of Ireland (RoI). Academic research on ‘fuel poverty’ produced in these two states has uncovered that the condition is brought about, in the main, by the interaction of low household incomes with thermally inefficient homes (Boardman, 2010). It has been underlined that the residents of inefficient dwellings are forced to purchase less affordable energy services than the rest of the population, because such homes are more expensive to heat. In relative terms, energy services are also less affordable to income-poor households, since such families will have lower amounts of disposable funds for such purposes. But the fact that fuel poverty is co-produced by energy efficiency and low incomes means that not all income-poor households will also be fuel poor. Additionally, the extensive nature of fuel poverty in the UK and RoI—itself a product of the two countries’ specific inequality patterns and housing stock structure—has allowed for an additional range of factors relevant to the rise of fuel poverty to be identified by researchers. This has included patterns of housing tenure, the nature of heating systems as well as socio-demographic circumstances such as household size, gender, class or education.
Scientists exploring the contingencies of energy poverty in the UK and RoI have often emphasized the deleterious health consequences of living in inadequately heated homes and the relationship between domestic energy deprivation and thermal efficiency interventions (Liddell & Morris, 2010). It has also been highlighted that energy poverty decreases the quality of life and influences social attainment. Authors working in this vein have argued that ‘raising incomes can lift a household out of poverty, but rarely out of fuel poverty’ (Boardman, 1991, p. xv), since residential energy inefficiency is the main reason for fuel poverty, and low-income households have to buy expensive warmth. Some researchers have pointed out that the spatial distribution of fuel poverty is highly sensitive to the way in which household incomes are measured. They have claimed that, regardless of the operational definition and measurement approach, households that need to spend more than 10 per cent of their income on energy on heating are generally not the same households as those in fact reporting difficulty in doing so.
As is argued in the sections that follow, such measurement and detection difficulties also apply to the wider European context. This chapter, therefore, first traces the evolution of work on energy poverty across Europe before reviewing the distribution and composition of energy-poor populations.
Energy Poverty in Continental Europe: Multi-sited Studies
The amount and depth of energy poverty-relevant research decrease rapidly once the focus is shifted away from the British Isles and onto continental Europe. Nevertheless, the generic causes of domestic energy deprivation in this context can be inferred from the emergent body of work pertaining to the European Union (EU) Member States and their neighbours. Similar to the UK and RoI, these arguments accepted that energy poverty in continental European countries arises out of a combination of low incomes and inefficient homes. However, it became increasingly recognized that the specific energy needs of a household—expressed via demographic circumstances such as household size, gender, occupation or class—also play a role. Of no less significance is the nature of housing tenure and heating system, since they may limit the energy efficiency interventions and fuel switching measures that can reduce energy costs (Bouzarovski & Simcock, 2017; European Commission, 2013; Pye et al., 2015).
Some of the initial non-UK and non-RoI scholarship about the energy and poverty nexus in multiple European countries included analyses of housing, fuel poverty and health in the European context, using data from the European Community Household Panel (ECHP). Contributions in this vein were based on a consensual approach, which ‘unlike traditional forms of measuring relative poverty … does not rely on the opinions or scientific postulates of academics or experts’ (Healy, 2017, p. xii). They combined objective housing data with ‘indicators of socially perceived necessities’ to demonstrate, inter alia, the central role of inefficient homes and poorly designed—or absent—heating systems in the production of energy poverty. Of note was a 14-country exploration of excess winter mortality: describing a seasonal increase in deaths that can be commonly attributed to ‘cold strain from both indoors and outdoors’ (Healy, 2003, p. 784). It linked information about thermal efficiency standards and mortality patterns with ‘longitudinal datasets on risk factors pertaining to climate, macroeconomy, health care, lifestyle, socioeconomics, and housing’ (ibid.). The results of this investigation established that ‘those countries with the poorest housing (Portugal, Greece, Ireland, the UK) demonstrate the highest excess winter mortality’ (Healy, 2003, p. 788); socio-economic well-being was also shown to play a role.
Also influencing early energy poverty debates was World Health Organization-led investigation of ‘housing, energy and thermal comfort’ in eight European countries, plus Kazakhstan and Kyrgyzstan. Using a range of independently gathered data, many of the country case studies within this inquiry established that seasonal winter mortality was a problem across Europe. Its conclusions underlined that ‘inadequate housing’ is the fundamental problem in this context. The authors also argued against a pan-European definition of ‘fuel poverty’, emphasizing that it may be ‘more appropriate to give guidance on the factors to be taken into account in developing a national definition’ (World Health Organization Regional Office for Europe, 2007, p. 10).
Among the most widely cited pieces of research in this domain are the results of the aforementioned EPEE (European Fuel Poverty and Energy Efficiency) project, which used three indicators from the SILC (Statistics on Income and Living Conditions) data set (‘ability to pay to keep one’s home adequately warm’, ‘leaking roofs, damp walls/floors/foundation, or rot on window frames/floors’, ‘arrears on utility bills’) to evaluate the extent of fuel poverty in Belgium, Spain, France, Italy and the UK . This data was then cross-referenced with information from other demographic indicators in SILC, as well as national surveys about the level of household incomes, as well as the nature of the housing stock and heating system. The study emphasized that one in seven households in Europe is in or at the margins of ‘fuel poverty’, locating the causes of the condition within the familiar context of low household incomes, insufficient heating and insulation standards and high energy prices.
Moving further east, the World Bank also sponsored an investigation of heating strategies among the urban poor in Croatia, Latvia, Lithuania, Moldova as well as Armenia, Kyrgyzstan and Tajikistan (Lampietti & Meyer, 2002). Even though this inquiry did not use an explicit ‘energy poverty’ lexicon, it did offer a broad-level investigation of household energy consumption and heating patterns in the selected countries. Having illuminated the wider relationship among heating, poverty alleviation and environmental quality issues, the research provided a series of policy suggestions about the necessary steps to design policies that will enable the provision of ‘clean heat’ in ‘fiscally sustainable ways’ (Lampietti & Meyer, 2002, p. 23). The study built on previous World Bank-led work in the region (Buckley & Gurenko, 1997; World Bank, 1999a, b).
Working along similar lines but with a stronger focus on social policy issues was an exploration of the social safety nets for energy price increases used by Bulgaria and Romania, in addition to Armenia and Kazakhstan (Velody, Cain, & Philips, 2003). Having established that ‘energy costs are the highest monthly expense after food for most low-income households in the region’ (Velody et al., 2003, p. vii), the study examined the poverty alleviation role played by three types of mechanisms: fuel assistance payments, energy efficiency improvements in low-income residences and ‘progressive’ tariff structures. It concluded that social protection instruments at the energy–poverty nexus were most effective if they provided a well-targeted and meaningful level of assistance, and were implemented via stand-alone and easily manageable mechanisms. The results of this work were echoed in a report on power sector affordability in South East Europe, which, having undertaken a series of analyses, found that many South East European countries have not yet developed adequate social safety mechanisms to protect energy-poor consumers (European Bank for Reconstruction and Development, 2003, p. 2).
There is also research that operates at a broader geographical scale, but in more narrow conceptual terms. A working paper published by the European Bank for Reconstruction and Development examined how ‘energy burdens’ (the share of household income devoted to energy) would change across 27 post-socialist countries in Eastern and Central Europe (ECE) and the Former Soviet Union (FSU) in a situation where ‘all utility prices are raised steadily to reach full cost recovery levels by 2007’ (Fankhauser & Tepic, 2007, p. 15). Having noted that ‘it is surprising how little we still know about the consumption patterns and well being of low income households’ (ibid.), its authors claimed that ‘delaying tariff adjustments may not be an effective way of mitigating the social impact of tariff reform’ (Fankhauser & Tepic, 2007, p. 15).
In their entirety, such studies confirm that one of the key driving forces of energy poverty in the Eastern European context have been energy price increases undertaken after the fall of communism, so as to bring electricity and gas tariffs—formerly subject to indirect subsidies by the state—up to cost-recovery levels. Work in ECE and FSU has thus revealed a series of ‘pervasive geographies’ of energy poverty arising from the failure of the state to respond to price increases with adequate social welfare support and energy efficiency investment (Buzar, 2007b). Other key driving factors include tenure patterns within the housing stock, as well as the regulation of energy markets; more recently a further complication has been added by the effects of the financial crisis and associated mortgage payments (Maxim, Mihai, Apostoaie, & Maxim, 2017). Nevertheless, a lack of unified approaches has been noted, in addition to the disproportionate coverage of energy poverty within social policy.
Much of this work has highlighted the significant difficulties faced by disadvantaged households in the region. It has demonstrated that, in addition to affordability and energy efficiency issues, important dimensions in the rise of energy poverty include the nature of household energy needs, as well as the fact that some demographic groups are ‘trapped’ in housing arrangements and heating systems that do not allow for switching towards less expensive and more comfortable ways of providing energy services (Buzar, 2007c; Tirado Herrero & Urge-Vorsatz, 2012). Research focusing on the relationship between a household’s awareness of climate change issues, on one hand, and energy efficiency retrofits, on the other, has also provided a range of energy poverty-relevant insights (Bouzarovski, 2015). It has highlighted that the poor quality of the housing stock may combine with the feeling of being too cold, hot or uncomfortable in driving energy-related renovations in privately owned dwellings (Bartiaux et al., 2012; Cirman, Mandič, & Zorić, 2013).
Energy poverty-relevant evidence can also be found in a study of ‘the effects of energy reforms on the probability of households experiencing deprivation, defined as difficulty in paying the bills’ (Rezessy, Dimitrov, Ürge-Vorsatz, & Baruch, 2006, p. 253). Authors working in this vein provide a range of statistical analyses of ECHP and SILC data for Denmark, Belgium, France, Ireland, Italy, the Netherlands, Spain, Austria, Finland, Luxembourg, Norway and Sweden. Their conclusions highlight that ‘unbundling vertically integrated activities in the electricity sector and reducing public ownership in the gas sector are both correlated with higher probability of experiencing deprivation’ (Rezessy et al., 2006, p. 262). Academics have also used statistical analyses of SILC and European Quality of Life Survey data to explore the relationship between self-reported energy poverty-relevant indicators and other socio-demographic and spatial variables (Thomson & Snell, 2013; Thomson, Snell, & Bouzarovski, 2017) .
In-Depth Research at the National and Local Scale
Research relevant to the causes and consequences of domestic energy deprivation has also been produced in relation to the circumstances of particular countries. One of the most influential debates in this regard commenced with a highly publicized paper on the welfare effects of raising household energy prices in Poland (Freund & Wallich, 1996). Its empirical analysis was based on data from the 1993 Polish household budget survey, ‘which contains information on the expenditures of 16,044 Polish households, surveyed between January and June 1993’ (Freund & Wallich, 1996, p. 55). Examining the expenditure patterns of households in five equivalent income quintiles led the authors to conclude that ‘not only did the better off spend a larger absolute amount on energy than the poor, they also consumed a larger proportion of their expenditures as energy’ (ibid.). A similar analytical approach was used in research of the extent to which ‘electricity tariff increases in Ukraine hurt the poor’ (Dodonov, Opitz, & Pfaffenberger, 2004, p. 855), whose authors recommended that price increases up to levels comparable to those in OECD (Organisation for Economic Cooperation and Development) countries ‘should only be realized in steps’ (ibid.).
The results of these studies have been favourably received in policy circles; the fact that their findings chimed in with the neoliberal agenda for energy sector unbundling and privatization pursued throughout Europe—and particularly in the East—after 1989 has allowed them to be widely cited in the literature on energy sector reform even though the use of elasticities and consumer surplus to estimate social welfare in conditions of ‘very high price increases’ has been problematized by some (Bacon, 1994). Many policy discussions of the distributional consequences of energy restructuring have widely cited the finding that implicit energy price subsidies benefit the ‘rich’ more than the ‘poor’ (Buzar, 2007a).
Also focused on issues of energy affordability as they relate to price increases is an investigation of the distributional effects of regulatory reforms in the Italian water and energy utility sectors (Miniaci, Scarpa, & Valbonesi, 2008). Using a range of regional, demographic and climatic indicators, its authors have constructed an affordability index for public utility consumption, so as to overcome the absence of an official energy poverty definition in Italy. Their findings, which are based on statistical modelling of large data sets from the Italian family budget survey, indicate that ‘in the period considered, reforms in the water, natural gas and electricity markets were not accompanied by exacerbated affordability issues in Italy’ (Miniaci et al., 2008, p. 162). More recent work has updated and developed these findings further, by exploring the wider context of network industry reform, as well as the role of regional policies (Florio, 2013; Scarpellini, Sanz Hernández, Llera-Sastresa, Aranda, & López Rodríguez, 2017).
There have also been several multinational organization-led studies using an explicit energy poverty framework in the design of research methods and approaches. A United Nations Development Programme-supported investigation in Serbia and Montenegro provided an integrated and comprehensive take on the relationship between energy, poverty and environmental problems. It introduced access considerations to the equation, by distinguishing between indicators relevant to the provision of energy services—including fuel consumption and the use of household energy appliances—and measures of the sufficiency of energy services, such as space heating, ventilation, domestic hot water and cooking (Kovačević, 2004).
Other ECE states have also been the subject of scientific attention in the field of domestic energy deprivation. The expansion of energy poverty in Bulgaria has been documented using interview and national household survey data, and with reference to EU and national policies. Part of the context for such work stems from the fact that in addition to having some of the highest rates of households reporting inadequate domestic thermal comfort in the SILC survey, this country has also implemented extensive energy privatization and liberalization reforms during the past 15 years (Bouzarovski, Petrova, & Sarlamanov, 2012; Lenz & Grgurev, 2017). Energy poverty in Poland has also been extensively studied and described thanks to the work of the Institute of Structural Research as well as several academic researchers (Miazga & Owczarek, 2015).
As we argued in a recent co-authored paper (Bouzarovski, Tirado Herrero, Petrova, & Ürge-Vorsatz, 2016), successive Hungarian governments have been making various attempts to buffer the impact of growing energy prices on the purchasing power of Hungarian households and voters. These politically motivated policy interventions have mainly taken the form of regulated energy prices and relatively short-lived subsidy schemes. Utility cuts are firmly entangled in political strategies to gain electoral support by confronting EU institutions and international corporations. Presented as the ‘battle of the utility bills’ (rezsiharc), such efforts were a central theme of the right-wing government’s campaign before the April 2014 general elections, in which the populist Fidész party achieved a new parliamentary majority. While it is likely that the measures have brought short-term benefits to low-income households by allowing for a reduction in energy burdens, their ability to address the wider spatial and infrastructural components of energy poverty and vulnerability is questionable. This is because they have preferentially supported urban consumers of natural gas and district heating, while failing to provide relief to households (mostly in rural areas) relying on bottled natural gas or firewood as a source of heat (Szivós, Bernát, & Kőszeghy, 2011). Also, there have been fears that the subsidies may increase rates of energy poverty by diverting resources that could be used for reducing the country’s supply dependency on Russia, or investing in residential energy efficiency.
Significant forays are also being made into scientific understandings of the underlying causes of energy poverty in various Southern European countries, where the condition has received almost no academic attention to date. This includes insights into the causes and patterns of energy poverty in Spain (Phimister, Vera-Toscano, & Roberts, 2015; Sánchez-Guevara Sánchez, Mavrogianni, & Neila González, 2017; Tirado & Jiménez Meneses, 2016); such work has demonstrated the existence of a close link between unemployment and energy poverty, in addition to establishing that existing social safety nets are failing to provide adequate assistance to energy-poor populations. An extensive study in the Greek capital Athens has uncovered the links between low incomes and energy efficiency by establishing that ‘low income people are more likely to be living in old buildings with poor envelope conditions’ (Santamouris et al., 2007, p. 893). Operating on a vastly different—but no less relevant—scale, research of energy-saving interventions in this country’s mountainous areas has led the author to conclude that ‘utilizing locally produced biomass and applying energy-saving measures can bring households below the energy poverty limit’ (Katsoulakos, 2011, p. 284). The geographies of energy poverty in Greece and Cyprus are now among the most studied in Europe (Atsalis, Mirasgedis, Tourkolias, & Diakoulaki, 2016; Boemi, Avdimiotis, & Papadopoulos, 2017; Boemi & Papadopoulos, 2017; Katsoulakos & Kaliampakos, 2016; Papada & Kaliampakos, 2017; Petrova, 2017; Santamouris et al., 2014), and work by Greek researchers has also contributed to an improved understanding of indoor conditions across Europe (Kolokotsa & Santamouris, 2015).
Western European countries have also attracted significant new interest. An exploration of the everyday strategies that are employed by Austrian households in order to alleviate domestic energy deprivation has revealed that ‘energy-inefficient windows, buildings and housing sites are the cause of heavy burdens’ (Brunner, Spitzer, & Christanell, 2012, p. 7) for this group. Conceptualizing processes of targeting, identification of households and implementation as three interdependent steps has highlighted the complex errors of inclusion and exclusion implicated in the design of France’s rapidly developing fuel poverty policy (Dubois, 2012). The increasing amount of public attention and state funding attracted by the energy poverty predicament in this country has been accompanied by the expansion of scientific research devoted to the issue, especially in terms of the relationship between vulnerability patterns and support policies (Bafoil, Fodor, & le Roux, 2014; Bartl, 2010; Legendre & Ricci, 2015; Ortar, 2016). Several recent contributions indicate that energy poverty is even present in countries like Germany, where rates of social inequality and inefficient housing are at record low levels (Becker, Kouschil, & Naumann, 2014; Billen, 2008; Großmann, Schaffrin, & Smigiel, 2016; Kopatz, 2009; März, 2017; Tews, 2014).
Geographic Patterns of Energy Poverty in Europe
The highest shares of populations with insufficient self-reported domestic warmth are concentrated in the part of the EU that is constituted by the post-socialist states of ECE (also referred to as the EU-10), especially Bulgaria. In such countries, the share of the population reporting inadequately heated homes has been 20.0 per cent, while the value of the composite fuel poverty indicator is 44.5 per cent. This is against EU-wide averages of 12.8 and 31.7 per cent, respectively. Also scoring high according to the same criteria are the eight EU countries that border the Mediterranean Sea, where 16.6 per cent of the population has reported being ‘unable to keep their home adequately warm’, while the composite fuel poverty indicator reaches 43.58 per cent.
In the index, the indicator Inability received a higher weight in order to reflect the greater importance that our assessment gives to self-reported thermal discomfort levels in comparison with the indicator Arrears, which keeps track of late payment levels in energy and other utility bills. At the same time, Housing faults is closely related to, but not necessarily a direct indicator of, energy poverty. Our weighted values approach was thus based on previously developed energy poverty indices and weight values (Thomson & Snell, 2013). It operated under the premise that consensual measures (such as the self-reported inability to keep warm) are insufficient to capture the complex economic and material underpinnings of energy poverty, and should be combined with indicators describing the housing and financial conditions of the population in order to obtain a fuller picture.

Thus, it can be argued that a core versus periphery distribution is a better descriptor of the spatial disparities in energy poverty rates across the EU than the traditional three-region model. The resulting European infrastructural divide is enmeshed in the improved macroeconomic performance and income levels among the latter group of states, as well as their higher-quality housing stock and more effective targeting of vulnerable groups. Overall, the principal differences between core and periphery countries are reflected in the degree of public recognition received by energy poverty, its socio-demographic extent as well as the structural drivers of the condition. While cultural differences may partly explain the disproportionately high prevalence of self-reported inadequately heated homes in Eastern, Central and Southern Europe, there is little doubt that energy poverty is objectively present in these parts of the continent to a much higher extent than elsewhere.
The structural causes of energy poverty in the two regions, however, are markedly different. As was pointed out in the previous sections of this chapter, ECE states have provided fertile ground for the expansion of energy poverty due to the unique combination of cold climates, above-average rates of inefficient residential buildings, insufficiently developed and/or decaying infrastructure, high rates of income inequality and systemic issues in the management of energy, social welfare and housing operations. The socialist centrally planned economy left behind an energy sector that was entirely state-owned and -run, with indirect cross-subsidies from industry to the residential sector creating a pricing structure whereby household energy tariffs were set at below cost-recovery levels. Consequently, most countries in the region undertook dramatic price increases in order to remove such subsidies, while unbundling and privatizing energy companies so as to open up the industry to competition.
During the post-socialist transition, however, most governments were unable to provide adequate social assistance and energy efficiency investment to protect vulnerable households from energy price increases. This meant that many families had no option other than to cut back on their energy purchases. The concurrent rise in income inequality and overall poverty, alongside the initial lack of concerted efforts to improve the energy efficiency of rapidly decaying housing stocks and energy infrastructures, has created a situation whereby energy poverty now includes large parts of the population. In Poland, for example, the average ‘energy burden’ (the share of energy expenditure within total household expenditure) has been steadily increasing throughout the post-socialist period, even though both absolute and relative poverty have fallen during the same period. This suggests that energy affordability problems are widespread among the population, and that the expansion of economic prosperity is failing to relieve the pressure of rising energy costs on household budgets.
In Bouzarovski et al. (2016) we found that energy burdens have been on the rise particularly rapidly in Hungary: from 11.6 per cent in 2005 to 16.9 per cent in 2011. While the figures for Hungary point to the pervasive presence of energy poverty across the country, neighbouring Poland and Czechia also face difficult circumstances in this regard—in light of the fact that the literature on the subject considers energy burdens near or at 10 per cent as a sign of hardship (Boardman, 1991; Fankhauser & Tepic, 2007), it is notable that significant numbers of households in all three countries have energy burdens above 20 per cent. This is where the comparatively greater size of the problem in Poland becomes more visible, as does the significant recent increase of the population affected by domestic energy deprivation in Hungary. In more general terms, it becomes apparent that post-communist energy sector reforms undertaken in all three countries—as well as the ability of nations like Poland to maintain GDP growth after the post-2008 financial crisis—have not translated into decreased energy costs or burdens for the general population and vulnerable groups alike.
The high prevalence of energy poverty in Southern European countries has been attributed to the lack of adequate heating systems, as well as the overall poor quality of residential dwellings, which has resulted in insufficient thermal insulation. In 2004, it was reported that only 12, 8, 6 and 16 per cent of Greek households had, respectively, cavity wall insulation, double-glazing, floor insulation and roof insulation in their homes (Healy, 2017). The situation was worse in Portugal, where the corresponding figures were 6, 3, 2 and 6 per cent. Nearly a quarter of Portuguese households had stated that they had rotten window frames, while a third revealed that they had patches of condensation on the indoor walls of their home (both of these conditions are considered good indicators of poor energy efficiency). Moreover, the same study found that 16, 19 and 11 per cent of households in, respectively, Greece, Portugal and Spain are suffering from leaking roofs, indicating the absence of adequate roof insulation. An additional problem in Mediterranean states is posed by the need for cooling. According to SILC data, 30 per cent of the population in the eight states bordering the Mediterranean Sea have reported that they are unable to keep their homes adequately cool in summer. Almost two-thirds of such households are considered income poor, while 70 per cent of them are above 65 years of age.
Countries such as the RoI, the UK—and to a lesser extent Belgium and France—constitute a third geographical realm with above-average rates of energy poverty in the EU. For example, it has been reported that indoor damp, itself a very strong indicator of energy poverty, is particularly prevalent in these countries (Healy & Clinch, 2002). For the reasons outlined above, the RoI and the UK developed a wide range of measures to combat the problem: in the UK, the Warm Homes and Energy Conservation Act, effective November 2000, resulted in the implementation of an unprecedented set of policies for fuel poverty reduction, embodied in the 2001 UK Fuel Poverty Strategy. According to this document, fuel poverty reduction targets should have been achieved by eliminating fuel poverty among ‘vulnerable’ households (older persons, sick and disabled households and families with children) by 2010, expanding to all households by 2016.
The large-scale geographic variations discussed above mean that energy poverty is particularly concentrated in Southeastern Europe, where millions of households are likely to be suffering from a lack of adequate domestic energy services. Conventionally vulnerable groups such as ‘pensioners, unemployed, low income households’ have been particularly hard-hit, especially in the states that have not yet developed ‘adequate social safety mechanisms’ to protect energy-poor consumers. The limited extent of certain types of networked energy infrastructures (particularly gas) means that, in addition to inefficient residential stocks and affordability issues, energy deprivation is also predicated upon the spatial and technical limitations associated with switching towards more affordable fuel sources in the home. The demise of district heating systems—associated with spiralling supply costs and vicious cycles of disconnection, and coupled with rapidly rising electricity prices—has meant that some parts of the population have had no option other than using fuel wood for heating. This is particularly evident in Bulgaria, where switching towards this source of energy has a clear income dimension (Bouzarovski et al., 2012).

As a result of these developments, firewood—the dominant solid fuel consumed by Hungarian households, alongside coal and woodchips—now trails natural gas as the second most common energy carrier for domestic space heating, even though both fuels are often used synchronously.
Difference Within Countries, Regions and Social Groups
Overall, the academic literature has found above-average rates of energy poverty among older people, families with children, and households with disabilities, long-term illness, or infirmity (Bouzarovski, 2014). In the Irish context, for instance, ‘over half of elderly households endure inadequate ambient household temperatures during winter’ (Healy & Clinch, 2002, p. 329). The EPEE project has also identified as vulnerable populations those out of work or in poorly paid jobs, and those dependent on social security benefits. Earlier, it was established that the group most susceptible to persistent energy poverty in the ‘older’ EU-15 states is single parents, followed by lone pensioners (Gray, 1995). It has also transpired that households living in multi-family apartment blocks are more likely to be suffering from energy poverty if they live in Northern as opposed to Southern Europe, partly due to income differentials. Tenure has also shown to be an important predictor of energy poverty, with households living in rental homes more vulnerable to the condition (Bouzarovski, 2014).
The scale of the energy burden is often a good predictor of the socio-demographic groups suffering from energy poverty. In Poland, for example, disproportionate expenditure on energy is correlated to household size among pensioners, with lone pensioners facing particular difficulties (ibid.). Above-average rates of energy expenditure can also be found in the case of all households headed by ‘manual’ workers and farmers. On average, large households are more likely to suffer from this condition compared to medium-sized households. Similar trends can be found across other Eastern European states.

There is little doubt that energy poverty is a pervasive problem across the EU, and is likely to expand in coming years as a result of anticipated energy price increases. For a long time, however, systematic research on issues of domestic energy deprivation in the much of the EU was scarce, especially in the countries of ECE and the Mediterranean where this condition is likely to be most pronounced. This means that, other than the UK and the RoI —which have a longer tradition of academic scholarship and policy frameworks to address the issue—energy poverty measures in many EU Member States are of an emergent nature.
Understanding the causes, content and consequences of European energy poverty is all the more pertinent in light of the increasing policy attention that is being paid to the issue within various EU institutions. In contrast to many mainstream efforts to reduce the problem to affordability or income poverty issues, however, much of the scholarship on the problem shows that the physical and institutional arrangements underlying built environment formations and everyday household practices are just as important in this context. Thus, enabling households to access energy at a materially and socially necessitated level is just as much a question of ensuring an adequate match between housing types, heating systems and household needs as it is about incomes and energy efficiency. In broader terms, therefore, building a comprehensive EU energy poverty agenda requires a conceptual shift in the mainstream theorization of domestic energy deprivation, away from the relatively narrow focus on poverty, access and energy efficiency, onto more complex and nuanced issues of household needs, built environment flexibility and social resilience.
The reviewed evidence also indicates that the driving forces of energy poverty are themselves embedded in locally specific social, political and environmental circumstances. For example, even though countries with colder climates would be expected to exhibit a greater incidence of energy poverty, the size of the population affected by domestic energy deprivation is estimated to be the lowest in Scandinavia; conversely, it has reached record levels in Southern Europe, where higher rates of income poverty and poorly insulated homes are clearly playing a determining role, in addition to the fact that many dwellings lack satisfactory heating systems. Similarly, despite possessing some of the highest energy prices in Europe, the incidence of energy poverty in Germany is judged to be significantly lower than that in, for example, Bulgaria, where energy prices are comparatively modest. In case of the latter, however, the underlying causes of the problem reside in the poor affordability of gas, electricity and heat services and the inadequate energy efficiency of the residential sector.
Much of the reviewed literature shows that energy poverty in many vulnerable ‘peripheral’ EU countries is expanding, while encompassing populations well beyond the low-income bracket. This is unlike better-off states—primarily in the North and West—where domestic energy deprivation seems to be predominantly concentrated among specific socio-demographic groups. Thus, the ability to capture energy poverty via the lens of income-based indicators is less meaningful in contexts where difficulties in securing adequate levels of energy services in the home are common within the general population. There is also evidence pointing to the presence of a distinct geographic distribution of energy poverty across Europe, whereby the socio-spatial underpinnings of the condition are aggregated with wider patterns of economic inequality. In many Eastern, Central and Southern EU Member States in particular, there is a tendency for domestic energy deprivation to be concentrated in rural and peripheral regions with poor-quality housing and decreased access to affordable fuels.
