    Spatial analysis of energy communities and energy vulnerabilities in Spain
    (Elsevier Ltd, 2025-05-11) Husiev, Oleksandr; Ukar Arrien, Olatz; Enciso-Santocildes, Marta
    Energy communities are increasingly recognized for promoting citizen-led transitions toward a just energy system. This paper provides an empirical study examining the distribution of collective action initiatives (CAIs) within Spain's energy transition, focusing on their alignment with local energy generation configurations and energy vulnerability, reflected in socio-economic conditions at the municipal level. This study uses spatial and statistical analyses to assess CAI distribution with a minimal set of socio-economic indicators characterizing basic dimensions of energy vulnerability and its standardized index, as well as energy assets across Spanish municipalities. Results show modest correlations between CAIs and indicators such as income levels and measures of income distribution. However, no significant link is found with income inequality, as measured by the Gini index, when considering high and low-population municipalities separately. Spatial clustering analysis with Local Moran's I reveals a low yet significant association between mean household income and low-capacity PV installations in neighboring areas, suggesting localized economic factors may influence renewable adoption patterns. The study also investigates CAIs' limited impact on addressing gender disparities within the energy sector, finding weak correlations with gender-balanced participation. These findings underscore the strengths and limitations of CAIs in supporting community resilience while highlighting their current insufficiency in addressing broader socio-economic inequalities. Furthermore, this paper discusses the results within a framework for preliminary CAI mapping within energy vulnerability contexts, offering insights for analytically-guided municipalities selection for in-depth, mixed-method exploration of community-led energy initiatives.

    Terminologies and concepts of energy cooperations in Europe: a systematic review of characteristics, potentials, and challenges
    (Elsevier Ltd, 2025-04) Arias Royo, Alba; Husiev, Oleksandr; Schwaller, Corinne; Sturm, Ulrike
    The development of energy communities and the promotion of decarbonisation of settlements through the implementation of renewable and local energy production sources has been emphasised in recent years by European agreements and agendas such as the European Green Deal, the Clean Energy for All Europeans Package, or the REPowerEU Plan. While these directives focus on Renewable Energy Communities and Citizen Energy Communities, the range of terms used in the field is much wider. For this reason, an in-depth analysis of academic literature on European energy cooperation initiatives was carried out for a five-year period between 2018 and 2023. This comprehensive literature review allowed to identify the types of cooperative energy initiatives that are being promoted in Europe to support the climate neutrality targets. The paper presents a systematic overview of the different terms used to describe energy cooperation initiatives, their organisational forms, the main actors involved, and their roles and levels of participation, the main purposes and motivations, social cohesion factors, financing systems and economic models, as well as challenges and benefits encountered. The findings allow to identify challenges and innovations that can more successfully promote the different forms of energy cooperations and thus support the decarbonisation of cities and communities by decentralising energy, using local and more sustainable resources, transgressing the current social, legal and market regulations, and involving different local actors, especially citizens, in the process.

    What does Horizon 2020 contribute to?: analysing and visualising the community practices of Europe's largest research and innovation programme
    (Elsevier Ltd, 2023) Husiev, Oleksandr; Ukar Arrien, Olatz; Enciso-Santocildes, Marta
    Decarbonising the world's energy system requires integrated and concise incentives to encourage citizens to participate actively in the energy transition. This article explores community-addressed practices within highly competitive energy projects of the Horizon 2020 framework programme. Compared with bibliometric research, analysing projects' open-platform databases in connection with academic literature can leverage the review and identification of practices in state-of-the-art research projects. In this regard, by applying methodology based on natural language processing techniques to a publicly available Horizon 2020 knowledge database, this paper generalises community-oriented approaches and solutions described in high-impact energy projects. The findings illustrate and characterise disproportions in generalised practices directed to energy consumption reduction, low-carbon energy generation, social economy, policy and strategy actions. Furthermore, the results discuss and exemplify specific projects in the context of the high-impact framework program's technical, socio-economic and socio-cultural matter. Finally, this research work has demonstrated the implementation of language processing within the custom implementation and certain limitations. Given its flexibility, the complex approach can be used as an easy-deployable lens to epitomize the thematic study and facilitate a discussion of trends in social and energy field research

    Why district renovation is not leading the race?: critical assessment of building renovation potential under different intervention levels
    (Elsevier Ltd, 2023-09-15) Husiev, Oleksandr ; Campos Celador, Álvaro ; Álvarez Sanz, Milagros; Terés Zubiaga, Jon
    Building is one of the main sectors in which significant energy savings can be achieved with a consequent reduction in emissions. This paper assesses the large-scale renovation of buildings, exploring the quantitative and qualitative factors that determine their replicability potential from three different perspectives, namely dwelling, building and district intervention level. Different passive and active measures are assessed, covering energy saving measures, the improvement of energy supply systems and the integration of renewable energy sources. Different scenarios are defined for each intervention level, which are evaluated using the methodology developed in the IEA-EBC Annex 75 project. The methodology is applied to a residential district located in Bilbao (Northern Spain). The analysis is based on the results obtained from the simulation of 41 combinations of different renovation options, obtained by simulation in the Design Builder software. The assessment is carried out from the evaluation of different key performance factors, including annualised cost and annual primary energy consumption, as well as the CAPEX and OPEX requirements. The results show that energy renovation of buildings offers a great opportunity for energy reduction at affordable investment costs, obtaining the cost optimal values when the intervention focus on the energy system and reaching net NRPE values close to zero when the intervention is carried out in a comprehensive way, considering energy systems and thermal improvement of the envelope. Additionally, the different energy reduction scenarios show that, while interventions at district level offer the greatest potential for minimising annual costs and primary energy consumption levels, intervening at building level offers only slightly worse results. However, there are other issues which can better explain the current low rate of renovation works in the urban environment. Thus, if the additional existing social, material and legal barriers and constraints are included in the analysis, it becomes clear why renovation from a district perspective is not actually leading the race. Given this situation, some measures and policies are proposed to realise the true potential of large-scale building renovation.
