Though the European Commission has repeatedly stated that the necessary energy transition in Europe should leave “no one behind”, this paper describes a building refurbishment case that has entailed economic hardships for the low-income families involved. The project is located in the area of P. D. Orcasitas in southern Madrid, led by a grassroots neighbours’ movement, comprising one hundred and seven housing blocks, containing more than 2000 dwellings. The main source of funding for the operation consists of subsidies granted by the Madrid City Council; however, Spanish legislation requires the state Agency of Tax Administration to classify these subsidies as capital gains derived from lucrative transfers. Based on the tax data of vulnerable beneficiaries, the conclusion is that the recipients have ended up returning part of the subsidies to the State through their Income Tax Return. In addition, the Spanish Social Security Institute requires the return of social benefits associated with non-contributory retirement pensions and the Minimum Living Income. Apart from tax accounting, regulations are revised to draw conclusions. Unlike most actuations of this kind, in this case the negative effects are obvious. Although intended to alleviate fuel poverty, the initiative has exacerbated vulnerability due to the impact of the imposed penalties on household income. In conclusion, unless preventive measures are implemented, the mandatory refurbishment of inefficient buildings may place an undue burden on vulnerable low-income occupants and hinder the effective implementation of energy-efficiency regulations.

This study proposes an integrated analytical framework (IAF) as a tool to simultaneously assess vulnerable social groups within their administrative context. This study hypothesizes that analyzing vulnerable groups through socio-spatial delineation reveals subnational disparities and sub-regional heterogeneity in energy poverty (EP) indicators, associated with additional context-sensitive environmental consequences of energy use. Using Hungarian deprived rural settlements (DRSs) (n = 300) as an example, mixed methods were applied to examine national–regional disparities, intra-regional variations, and the environmental implications of extreme household energy use practices. Results show that both socio-economic indicators and building energy efficiency, and energy-use profiles, fall short of national indicator performance. The sample outlined by the IAF performed homogeneously regarding socio-economic circumstances and showed mild differences in housing quality and energy access. These results indicate not structural differences but variation in underlying regional drivers, highlighting the region-specific manifestation of EP. The energy-use-related environmental assessment was performed using a parametrized building-stock model and the two most extreme energy-use scenarios for households relying on solid fuels. The results suggest that the use of substitute fuels substantially increases the combined emissions of CO₂, CO, PM, NOx, and SOx by up to 32 percentage points. Although limitations constrain the reporting of empirically representative results, findings underscore the potential policy relevance of DRSs in national climate objectives. Full article

The building sector is responsible for 40% of CO₂ emissions in Portugal, making the integration of renewable energy systems increasingly relevant. Photovoltaic (PV) technologies have become more accessible due to declining levelized costs of energy, and when coupled with battery energy storage systems (BESSs), they can enhance grid independence, reduce household energy expenses, and mitigate peak load stress. However, high upfront costs still limit adoption, particularly among vulnerable communities. This study evaluates the technical, economic, and environmental performance of PV systems, with and without BESSs, compared with an existing solar thermal configuration in a social-housing neighbourhood in Porto, Portugal. Numerical simulations were conducted for three scenarios, optimising system sizing and ensuring hourly energy flow balance between generation, storage, and grid supply. Results indicate that all configurations are technically feasible within Porto’s climate conditions, though with distinct investment needs, payback periods, and CO₂ reduction outcomes. The findings offer practical guidance for designing renewable energy solutions tailored to social housing, supporting both decarbonization goals and long-term mitigation of energy poverty.

Sustainability and the Sustainable Development Goals (SDGs) are garnering significant attention due to growing global challenges, including poverty, inequality, environmental degradation, and climate change, with the latter addressed specifically through SDG 13. This study examined the level of self-reported awareness of six science-related SDGs—SDG 3 (Good Health and Well-Being), SDG 6 (Clean Water and Sanitation), SDG 7 (Affordable and Clean Energy), SDG 13 (Climate Action), SDG 14 (Life Below Water), and SDG 15 (Life on Land)—among science teachers in the Arab sector in Israel as a function of background variables: gender, seniority, degree type, academic institution, school type, area of specialization, and the integration of these SDGs into the science curriculum. The study employed a mixed-methods approach: in the quantitative component, 204 science teachers responded to a Likert-scale questionnaire; the qualitative component consisted of semi-structured interviews with 30 middle school science teachers from the Arab sector. The findings indicated a moderate level of self-assessed awareness regarding SDGs. Significant differences in awareness were found according to teaching subject: environmental studies teachers demonstrated the highest awareness, followed by general science, biology, and physics teachers, with chemistry teachers ranking lowest. No significant differences were found for the remaining variables (p > 0.05). Qualitative findings indicated that while teachers perceived SDG-related content as implicitly present in the curriculum, explicit and systematic integration of the SDG framework is largely absent. Overall, the findings suggest that teachers are not adequately exposed to the SDGs. Therefore, it is recommended to incorporate these topics into teacher-training courses and professional development programs and to further integrate them into curricula. This study contributes to the growing body of research on SDG integration in science education, particularly within underexplored minority educational contexts. Full article

Green finance seeks to reconcile economic expansion with environmental protection and may, by relaxing financing constraints on clean-energy projects, contribute to lower energy poverty. Using provincial panel data from China over 2010–2019, this study examines the relationship between green finance development and energy poverty and evaluates potential spatial spillovers. The results show that green finance development is negatively associated with energy poverty, and this relationship remains statistically robust in dynamic-panel specifications estimated using system generalized method of moments (system GMM). Mechanism analyses further provide suggestive evidence that this negative association may operate partly through greater energy-supply investment and improved energy-infrastructure conditions. Spatial econometric evidence also indicates the presence of spillover effects: improvements in green finance in one province are associated with lower energy poverty in neighboring provinces. These findings imply that efforts to eradicate energy poverty should explicitly incorporate green finance, recognize regional heterogeneity in green finance development, and improve the transmission of green finance into tangible investment in clean energy and energy infrastructure. Interprovincial policy coordination is also warranted given spatial interdependence. Full article

Thermal comfort is among the primary determinants of habitability in the built environment. In tropical developing countries, however, its treatment in public housing policy has often been limited, fragmented, and, in many cases, subordinated to energy-saving criteria that do not adequately reflect occupant needs or local climatic diversity. This study analyses the integration of thermal comfort within housing policy using a mixed-methods approach combining regulatory analysis with post-occupancy environmental monitoring. Empirical monitoring shows average indoor temperatures between 16.3 °C and 18.5 °C, with more than 80% of recorded hours falling below adaptive comfort thresholds and a predicted dissatisfaction rate (PPD) of approximately 47%. These findings demonstrate that compliance with efficiency-centred sustainability regulation does not necessarily ensure thermally adequate indoor conditions in occupied social housing, highlighting a structural gap in current regulatory frameworks between efficiency-based compliance and thermally adequate indoor conditions in occupied social housing. The analytical framework integrates three dimensions: policy analysis, environmental performance verification, and interpretation of occupant adaptive behaviour. Rather than claiming that Bogotá is statistically representative of all tropical conditions, the paper treats it as an analytically revealing case in which tensions among efficiency-centred regulation, imported comfort standards, and constrained occupant adaptation become visible. The paper also demonstrates that the current Colombian sustainability regulation (Resolution 0194 of 2025) operationalises sustainability primarily through energy and water saving targets and climatic zoning, while lacking explicit, verifiable indicators for thermal comfort, occupant well-being, or health outcomes. Finally, the paper discusses the relevance of locally calibrated standards, standardised field methodologies, and passive design strategies within a broader agenda of energy governance, environmental equity, and housing adequacy.

Recent geopolitical tensions and the global energy crisis have highlighted the urgent need to shift from traditional energy supply models towards sustainable solutions involving active participation from citizens, public authorities, and private actors. Renewable Energy Communities (RECs) are emerging as a novel form of community-based entrepreneurship grounded in social innovation and participatory governance, capable of generating economic and socio-environmental benefits. This study presents a systematic literature review using the PRISMA methodology, based on a Scopus search until 10 August 2025, to identify key research trends in the social and political dimensions. The final corpus includes 45 peer-reviewed journal articles, classified into two dimensions: 26 addressing the social dimension, centred on acceptance, engagement, trust, and behavioural drivers; and 19 focusing on the political, encompassing regulatory frameworks and governance arrangements. The review reveals that social factors mobilise and sustain collective participation, while political ones reduce coordination costs and support replication. Crucially, the analysis points to the social legitimacy that sustains RECs but cannot ensure their diffusion without institutional support; conversely, enabling frameworks fail to deliver scalable outcomes when not anchored in local acceptance and participation. Furthermore, the review identifies the potential of RECs in addressing energy poverty, distinguishing between empirical evidence and normative expectations. These findings are particularly relevant for territorially fragile areas, where RECs can foster resilience and inclusivity. Full article

Electrification is vital for economic growth, poverty reduction, and improved quality of life. Over 80% of Afghanistan’s rural population lacks electricity. Despite increasing interest in decentralized energy systems, there remains a lack of site-specific studies that jointly assess the technical, economic, and policy feasibility of decentralized solar PV for rural electrification in Afghanistan. This study addresses that gap through a mixed-method case study of Syahgel, Ghazni, combining a household survey of 30 households, PVsyst-based system sizing, economic evaluation, and policy analysis. The study compares multi-tier Solar Home Systems (SHSs) with a community microgrid under local demand and affordability conditions. The results show that SHSs, with entry-level costs starting from USD 95, are more suitable for small, dispersed settlements, while microgrids remain relevant for larger or more concentrated communities. Financing mechanisms, including subsidies and interest-free loans, can improve affordability by up to 75%, while electrification can reduce annual fuelwood expenditure by approximately USD 51.5 per household and generate broader health, educational, and livelihood benefits. The findings highlight the need for integrated policy reform, targeted financial support, and context-sensitive system design to support sustainable and inclusive rural electrification in Afghanistan.

Energy poverty remains an important challenge for sustainable development in China, with pronounced regional disparities and evolving temporal dynamics that require accurate and interpretable prediction tools. This study develops a provincial panel-based framework that combines Energy Poverty Index (EPI) construction, SSA-LSTM prediction, SHAP-based model interpretation, and two-way fixed effects (TWFE) regression analysis. Using provincial data for China (2003–2022), we first construct a composite EPI with the entropy weight method, then apply a Sparrow Search Algorithm (SSA) to optimize LSTM hyperparameters for EPI forecasting. SHAP is used to interpret feature contributions to model-predicted EPI, and TWFE regression is used to provide complementary panel-data evidence on factor–EPI associations. The results show that the SSA-LSTM model outperforms benchmark machine learning and deep learning models in out-of-sample prediction performance. SHAP-based interpretation indicates that variables such as GDP, energy intensity, and power generation per capita contribute strongly to prediction variation, with notable regional heterogeneity. TWFE results are broadly consistent with several key patterns identified in the SHAP analysis. Overall, the proposed framework provides an accurate and interpretable provincial energy poverty prediction approach and offers a useful empirical reference for energy poverty monitoring and policy discussion.

Population aging and climate change are two long-term processes that increasingly intersect, yet their interrelationship remains insufficiently explored in Southeast Europe. This article examines how adults aged 50+ in Serbia and Bulgaria understand, perceive, and respond to climate risks, with the aim of identifying age-specific vulnerabilities as well as opportunities for climate action. We administered the ClimateMind50+ questionnaire to purposive national samples comprising 309 respondents in Serbia (CAPI, 82 municipalities) and 155 respondents in Bulgaria (CAWI, 74 municipalities). Socio-demographic differences were analyzed using descriptive statistics and χ² tests. The findings indicate moderate levels of self-assessed climate literacy, strong concern about the impacts of climate change on future generations, and heightened anxiety regarding extreme heat and prolonged dry periods. During climate-related emergencies, respondents rely predominantly on family networks rather than local institutions, and overall preparedness for extreme events remains limited. Adaptive and pro-environmental behaviors are modest and vary by gender, education level, and type of settlement. Population aging interacts with socio-economic vulnerability, energy poverty, regional decline, and governance constraints, shaping both exposure to climate risks and the capacity for behavioral adaptation. Climate strategies in both countries should therefore become more age-inclusive and socially responsive, recognizing older adults not only as a vulnerable group but also as active contributors to resilience.

This study explores Nigeria’s bioenergy industry’s potential in reducing unemployment. It focuses on two objectives: first, to determine how the development of the bioenergy sector can reduce Nigeria’s unemployment rate, and second, to identify effective policy instruments to harness the potential of the bioenergy industry in Nigeria. Using a Forest and Agricultural Sector Optimization Model for Nigeria, this study modeled three scenarios with varying labor wage rates. The second scenario used an hourly wage of US$0.38/h for US$3.00 purchasing power parity (PPP), reflecting the International Labor Organization’s global minimum PPP. The first and third scenarios applied prices slightly below and well above the PPP at the rate of US$0.32/h for US$2.56 PPP and US$1.04/h for US$8.30 PPP, respectively. This was modeled against the baseline labor rate (Nigeria’s minimum wage of 45 USD/month, approximately US$0.28/h, equivalent to 70,000 NGN). Nigeria’s current energy and food security targets and policies are also implicitly implemented. The product-demand driver is the Nigerian population data projection, which aligns with the Shared Socioeconomic Pathways (SSPs) for Scenario 2. Results reveal that while increases in the labor wage rate improve labor welfare above the global poverty threshold, they also impact the bioenergy sector and the aggregated total economic welfare. Results highlight an optimal wage balance where employment growth in the bioenergy sector can be sustained without compromising production capacity or aggregated total welfare. Based on these insights, actionable policy implications from this study include implementing moderate wage growth, subsidies, and productivity investments to maximize bioenergy’s potential as a sustainable employment generator in Nigeria.

Public buildings and open spaces form key elements in an exchange system of both tangible resources (energy, water, physical spaces) and intangible assets (services, skills, time). This study presents an innovative protocol (AGAPE—Automatic GIS Assessment Protocol for Energy and environment) to regenerate metropolitan suburbs by managing common resources and support sustainable communities. It tackles energy poverty by integrating urban planning, environmental design, and economics into geographic information science. This expedites public well-being by redesigning public facilities to enhance community connections and improve bioclimatic resilience. The model test site is a peripheral suburban area, Melito di Napoli, within the Metropolitan City of Naples (Italy), characterized by high population density and ongoing suburban expansion. The protocol evaluates temporal scenarios for implementing multi-purpose solutions, supporting public agencies in strategic intervention assessments, optimizing funding allocation and community benefits. The modeling of redesigned community assets reveal key outcomes: renewed land-use opportunities, reduced spatial inequities, and increased climate change resilience. The transformation of public buildings and facilities into multi-benefit community cores catalyzes virtuous urban regeneration processes. The model AGAPE provides a replicable decision framework to transform existing settlements and to drive the transition towards more sustainable, equitable urban communities. Full article

Approximately 70% of the Nigerian population experiences energy poverty. The country generates about 4500 MW of electricity for over 200 million people, and half of its population lacks reliable access to power. With that in mind, this study aims to examine the various aspects of energy poverty in Nigeria and to provide steps to address this as well as recommendations. The study employed both quantitative and qualitative methodologies to reveal that energy poverty in Nigeria is largely a result of inadequate infrastructure and poor governance, and is heavily dependent on traditional, harmful energy sources. Additionally, poor maintenance and deterioration of energy facilities, as well as government corruption, also contribute to this. Both methodologies are used in the review because they provide a comprehensive, holistic, and validated understanding of the study by merging statistical precision with deep, contextual insight. The review establishes that Nigeria’s power sector faces financial difficulties, inefficient distribution networks, and significant energy losses, all of which further complicate efforts to meet rising electricity demand. Policy interventions and the other factors mentioned in the study are ways to address energy poverty in the country. Hence, policies that aim to increase access to affordable, reliable energy are welcome and recommended. Through this medium, policymakers are responsible for ensuring sustainable economic growth in the long term, which will benefit and promote the country. Full article

The main aim of this study was to determine the share of Polish household income allocated to energy, taking into account socioeconomic diversity and income quintile distribution, as well as to identify changes in the burden of energy expenditures on budgets. The importance of this topic stems from the energy transformation of the European Union and the significant increase in energy prices in recent years, which may exacerbate existing energy poverty in Poland. The study utilized numerical data on household budgets published within Polish public statistics. The following measures were used: mean, quintiles, structure indicators, and fixed- and chain-based indices, as well as the relationship between income and expenditure (correlation coefficients). The research was conducted using data from 2014–2022 or selected years within this period. The highest share of energy expenditures in total expenditures was recorded among households of annuitants and farmers. However, annuitant households have the lowest incomes and are most vulnerable to energy poverty. The disparity in energy expenditure between the wealthiest and poorest households has narrowed. Educational efforts on energy efficiency in households should therefore continue, alongside the development of support mechanisms for those with the lowest incomes. Full article
