Rapid urbanization has intensified the environmental impacts of residential neighborhoods as key nodes of urban energy consumption and carbon metabolism. This study integrated life cycle theory with emergy ecological footprint analysis to quantify the sustainability of a residential neighborhood in Wuhan. The analysis revealed distinctive patterns in renewable energy utilization, where rainwater chemical energy and earth cycle energy constitute the primary contributions, supplemented by rain geopotential energy and solar energy, with minimal wind energy participation. Assessment of Building L₆ over its 70-year service life demonstrated that the operational phase dominates the emergy ecological footprint (EEF) at 1.86E+07 hm², greatly exceeding contributions from pre-construction (1.072E+05 hm²), demolition (2.133E+4 hm²), and construction phases (1.14E+3 hm²). The neighborhood's total emergy ecological carrying capacity (EECC) of 1.50E+3 hm² was vastly overwhelmed by its cumulative EEF of 1.823E+8 hm², resulting in a significant ecological deficit (EEDs < 0). In order to verify the accuracy of the data, a sensitivity analysis was conducted. This severe imbalance indicated substantial environmental pressure, primarily attributable to long-term operational energy demand and material preprocessing. In response, this study proposes targeted strategies including enhanced renewable energy integration, optimized construction management, adoption of high-efficiency low-emission building systems, and reduced reliance on conventional cooling technologies. This research provides both a methodological framework for neighborhood-scale sustainability assessment and practical guidance for reducing environmental impacts in urban development.

快速城市化加剧了住区作为城市能源消耗和碳代谢的关键节点对环境的影响。本研究将生命周期理论与能量生态足迹分析相结合，对武汉市某住宅小区的可持续性进行量化。分析揭示了可再生能源利用的独特模式，其中雨水化学能和地球循环能是主要贡献，雨水地势能和太阳能是补充，风能参与最少。对L6号楼70年使用寿命的评估表明，运营阶段的能量生态足迹（EEF）占主导地位，为1.86E+07 hm2，大大超过了施工前（1.072E+05 hm2）、拆除（2.133E+4 hm2）和施工阶段（1.14E+3 hm2）的贡献。邻域的总能生态承载力（EECC）为1.50E+3 hm2，而其累计能生态承载力（EEF）为1.823E+8 hm2，导致了显著的生态赤字（eed < 0）。为了验证数据的准确性，进行了敏感性分析。这种严重的不平衡表明了巨大的环境压力，主要是由于长期的运营能源需求和材料预处理。为此，本研究提出了加强可再生能源整合、优化施工管理、采用高效低排放建筑系统以及减少对传统制冷技术依赖的针对性策略。本研究既为社区尺度的可持续性评价提供了方法框架，又为减少城市发展中的环境影响提供了实践指导。

Addressing energy poverty (EP) has become a requirement in the design of modern energy efficiency mechanisms, particularly under Energy Efficiency Obligation Schemes (EEOS), as reflected in the 2023 recast European Union Energy Efficiency Directive. In this context, Türkiye's plan to introduce an EEOS by 2027 offers a strategic opportunity to incorporate social targeting into energy efficiency policy. Yet, the absence of a systematic methodology for identifying energy-poor households remains a key challenge. This study presents a data-driven and multidimensional targeting framework that integrates structural inefficiencies, financial vulnerability, and regional disparities. Using 2023 microdata from the Survey of Income and Living Conditions, the methodology begins by filtering households based on housing-related inefficiencies. A custom Eligibility Index is then constructed using carefully selected financial difficulty indicators, with indicator weights assigned through Multiple Correspondence Analysis. To segment households without relying on arbitrary thresholds, a k-prototypes clustering algorithm is applied, yielding three distinct groups: Priority Energy-Poor, At-Risk, and Regular. Among Türkiye's estimated 15 million inefficient households, 2.25 million are identified as Priority Energy-Poor, requiring fully subsidised interventions under EEOS. At-Risk households represent an additional 4.5 million and would benefit from preventive support. The remaining 8.25 million Regular households could be reached through co-financing schemes. The spatial distribution of these groups reveals significant regional inequality, emphasizing the need for geographically adaptive policies. The proposed methodology offers a replicable framework for socially inclusive EEOS implementation and highlights the urgent need to expand national data systems to support evidence-based energy efficiency planning.

正如2023年修订的欧盟能源效率指令所反映的那样，解决能源贫困（EP）已成为现代能效机制设计的一项要求，特别是在能效义务计划（EEOS）下。在这种背景下， rkiye计划在2027年之前引入EEOS，这为将社会目标纳入能源效率政策提供了战略机遇。然而，缺乏确定能源贫乏家庭的系统方法仍然是一个主要挑战。本研究提出了一个数据驱动的多维目标框架，整合了结构性效率低下、金融脆弱性和地区差异。该方法使用了《收入和生活条件调查》（Survey of Income and Living Conditions）的2023年微数据，首先根据与住房相关的低效率对家庭进行筛选。然后使用精心选择的财务困难指标构建自定义资格指数，并通过多重对应分析分配指标权重。为了在不依赖任意阈值的情况下对家庭进行分割，应用了k-原型聚类算法，产生了三个不同的组：优先能源匮乏组、风险组和常规组。在斯里兰卡估计的1500万户低效家庭中，225万户被确定为优先能源贫乏户，需要根据平等就业机会法进行全面补贴干预。另外450万处于危险中的家庭将受益于预防性支助。其余的825万普通家庭可以通过共同筹资计划获得资助。这些群体的空间分布揭示了显著的区域不平等，强调了制定地理适应政策的必要性。提出的方法为社会包容性的EEOS实施提供了一个可复制的框架，并强调了扩大国家数据系统以支持循证能源效率规划的迫切需要。

Universal access to affordable and reliable electricity remains a cornerstone of Sustainable Development Goal 7, yet many remote regions continue to face persistent barriers to electrification. Mae Hong Son Province in northwestern Thailand represents the nation's lowest electrified region, with 22.2% of its main villages remaining unserved. This study applies the PESTEL analytical framework—Political, Economic, Social, Technological, Environmental, and Legal—to systematically examine the multidimensional barriers to achieving full electrification in the province. Data was collected through document analysis and semi-structured interviews with government agencies, technical experts, and residents. A total of 39 barriers were identified across the six dimensions. While several factors, such as inadequate funding and grid inaccessibility, are consistent with challenges in other developing contexts, Mae Hong Son presents distinct barriers related to protected forest regulations and the legal status of Hill Tribe settlements. Institutional obstacles—particularly lengthy and complex permitting procedures—emerged as the most critical constraint. The study provides the first comprehensive, PESTEL-based assessment of rural electrification barriers in Thailand and delivers policy-relevant insights to support inclusive, sustainable, and context-specific electrification strategies that strengthen energy equity and socio-economic resilience in remote communities.

普遍获得负担得起和可靠的电力仍然是可持续发展目标7的基石，但许多偏远地区在电气化方面仍然面临持续的障碍。泰国西北部的湄丰顺省是全国电气化程度最低的地区，22.2%的主要村庄仍未通电。本研究应用PESTEL分析框架——政治、经济、社会、技术、环境和法律——系统地考察了该省实现全面电气化的多方面障碍。通过文献分析和与政府机构、技术专家和居民的半结构化访谈收集数据。在六个维度上共确定了39个障碍。虽然资金不足和电网不通等几个因素与其他发展中国家面临的挑战一致，但Mae Hong Son在森林保护法规和山地部落定居点的法律地位方面存在明显的障碍。制度上的障碍——特别是冗长而复杂的审批程序——成为最关键的制约因素。该研究首次对泰国农村电气化障碍进行了全面的、基于pestel的评估，并提供了与政策相关的见解，以支持包容性、可持续和因地制宜的电气化战略，从而加强偏远社区的能源公平和社会经济复原力。

The widespread use of solid biomass in developing countries presents a critical paradox: while promoted as a renewable and accessible energy source, its unregulated combustion generates severe indoor air pollution and entrenches environmental injustice. This study examines how biomass energy governance fails to internalize health and equity concerns by comparing the legal and regulatory frameworks of Vietnam and India with the EU's evolving model under the Renewable Energy Directives II and III (RED II/III). Using a combined doctrinal, comparative, and case-law methodology, supported by WHO and IEA data on health and emission impacts, the analysis reveals that Vietnam and India rely predominantly on incentive-based and programmatic policies that lack enforceable standards on lifecycle greenhouse gas emissions, sustainable feedstock sourcing, and indoor air quality. By contrast, the EU framework institutionalizes precaution and accountability through binding lifecycle and traceability requirements. The study advances energy justice scholarship by demonstrating that the sustainability of biomass energy is ultimately a legal question and by proposing a justice-oriented regulatory framework that embeds enforceable health, equity, and sustainability obligations within energy law.

固体生物质在发展中国家的广泛使用造成了一个严重的矛盾：虽然作为可再生和可获得的能源加以推广，但其不受管制的燃烧产生了严重的室内空气污染，并加剧了环境的不公正。本研究通过比较越南和印度的法律和监管框架与欧盟在可再生能源指令II和III （RED II/III）下不断发展的模式，探讨了生物质能治理如何未能将健康和公平问题内部化。在世卫组织和国际能源署关于健康和排放影响的数据的支持下，采用理论、比较和判例法相结合的方法，分析表明，越南和印度主要依赖基于激励和规划的政策，这些政策在生命周期温室气体排放、可持续原料采购和室内空气质量方面缺乏可执行的标准。相比之下，欧盟框架通过绑定生命周期和可追溯性要求将预防和责任制度化。该研究通过证明生物质能的可持续性最终是一个法律问题，并提出了一个以正义为导向的监管框架，将可执行的健康、公平和可持续性义务嵌入能源法，从而推进了能源正义学术研究。

Agrivoltaic (AV) systems enable the simultaneous use of land for agricultural processes and solar photovoltaic (PV) power production. However, the performance of AV systems is often hampered by inefficient irrigation methods and the continued dependency of irrigation and other farming activities on the grid electricity. Improving irrigation efficiency and decreasing this dependency on grid is necessary to sustain agricultural productivity in AV systems. In order to meet this issue, a mesh grid-based geographic information system (GIS) framework provides high-resolution spatial, solar potential maps for the estimation of power production from AV. Crop suitability within the AV system is determined using soil triangle–aided analytic hierarchy process (AHP), incorporating variations in soil texture and climatic conditions. Additionally, a situational awareness (SA)-oriented conceptual framework related to adaptive irrigation has been proposed by infusing the factors of soil moisture, climate, and the availability of power from AV. The outcomes show a (25–30) % reduction in grid dependence for irrigation. This proposed integrated data-driven framework shows the ability to reduce the reliance on the grid, thereby offering the potential to make the adaptation of AV systems to climate variability and resource constraints more effective and efficient.

农业光伏（AV）系统能够同时利用土地进行农业加工和太阳能光伏（PV）发电。然而，由于灌溉方法效率低下以及灌溉和其他农业活动对电网电力的持续依赖，AV系统的性能经常受到阻碍。提高灌溉效率和减少对电网的依赖是维持AV系统农业生产力的必要条件。为了解决这个问题，基于网格的地理信息系统（GIS）框架提供了高分辨率的空间太阳能潜力图，用于估计AV的电力生产。利用土壤三角辅助层次分析法（AHP）确定AV系统内的作物适宜性，结合土壤质地和气候条件的变化。此外，通过注入土壤湿度、气候和AV的电力可用性等因素，提出了一个与适应性灌溉相关的以情景感知（SA）为导向的概念框架。结果表明，灌溉对电网的依赖降低了（25-30）%。这个拟议的综合数据驱动框架显示了减少对电网依赖的能力，从而提供了使自动驾驶系统更有效和高效地适应气候变化和资源限制的潜力。

India's rapid economic growth is driving a surge in electricity demand, with peak demand projected to reach 366 GW by 2031–32. The Government of India aims to develop 500 GW of renewable energy (RE) capacity by 2030. As the nation integrates renewable energy to meet these targets, the variability of these sources necessitates robust energy storage solutions. This paper investigates the techno-economic viability of integrating Grid-connected Battery Energy Storage Systems (BESS) within a large state-owned distribution company (DISCOM) for the target year 2027–28. DISCOMs are the key stakeholders to the success of large-scale deployment of RE resources and its integration in India. Deploying BESS at the distribution level can offer several techno-economic benefits to DISCOMs and further accelerate the country's renewable energy initiatives.

The study utilizes a Mixed Integer Linear Programming (MILP) based simulation model MiPower Power System Optimization (MiPSO) and MiPower for load flow analysis to quantify five distinct value streams, revenue streams, and value stacking: firm capacity Power Purchase Agreement (PPA) deferral, energy arbitrage, Deviation Settlement Mechanism (DSM), reactive power support, and network charge savings (State transmission and General Network Access charges). The BESS capacity is estimated through grid assessment, demand and supply evaluation, and resource adequacy plans.

It identifies that the financial analysis, based on a CAPEX of $165/kWh the identified BESS capacity can provide a payback period of 4–5 years, with an Internal Rate of Return (IRR) of 31.07%, Net Present Value (NPV) of INR 65.42 billion and a levelized cost of storage of INR 2.44/kWh which is equivalent to the normal solar power in India. The deployment is projected to reduce the DISCOM's effective tariff by approximately 9.64 paisa/kWh (0.1% reduction in tariff) in the first year. These findings provide a strategic framework for DISCOMs to leverage BESS for economic optimization, grid stability, and efficient capital expenditure.

印度经济的快速增长推动了电力需求的激增，预计到2031年至2032年，峰值需求将达到366吉瓦。印度政府的目标是到2030年发展500吉瓦的可再生能源（RE）容量。随着国家整合可再生能源以实现这些目标，这些能源的可变性需要强大的储能解决方案。本文研究了大型国有配电公司（DISCOM）在2027-28年目标年整合并网电池储能系统（BESS）的技术经济可行性。discom是印度成功大规模部署可再生能源资源及其整合的关键利益相关者。在配电层面部署BESS可以为DISCOMs提供多项技术经济效益，并进一步加速该国的可再生能源计划。该研究利用基于混合整数线性规划（MILP）的模拟模型MiPower电力系统优化（MiPSO）和MiPower进行负荷流分析，量化五个不同的价值流、收入流和价值堆叠：企业容量电力购买协议（PPA）延期、能源套利、偏差解决机制（DSM）、无功支持和网络费用节约（状态传输和一般网络接入费用）。BESS容量是通过电网评估、需求和供应评估以及资源充足性计划来估计的。它确定了财务分析，基于165美元/千瓦时的资本支出，确定的BESS容量可以提供4-5年的投资回收期，内部收益率（IRR）为31.07%，净现值（NPV）为654.2亿卢比，平均存储成本为2.44卢比/千瓦时，相当于印度的正常太阳能发电。预计该部署将在第一年将DISCOM的有效电价降低约9.64帕萨/千瓦时（电价降低0.1%）。这些发现为DISCOMs利用BESS实现经济优化、电网稳定和高效资本支出提供了战略框架。

Southern Chile faces severe air pollution driven by residential firewood use and energy poverty. This study evaluates the effectiveness of thermal retrofitting policies in Coyhaique through a multidimensional analysis of 68 households, combining sociodemographic surveys, indoor temperature monitoring, and an assessment of housing typologies and their transformations. Results indicate that lower-income households consume significantly more energy per square meter yet achieve lower thermal comfort duration. While retrofitting improves indoor temperatures, it fails to decouple households from polluting fuels; notably, in 62% of retrofitted dwellings, the use of firewood persists due to ingrained cultural and economic factors. The findings highlight that current policies, characterized by a lack of inter-ministerial coordination and standardized designs, fail to address the specific socio-technical realities of intermediate cities. We conclude that effective decontamination requires a transition from sectoral approaches to integrated territorial management, aligning housing quality standards with local energy transition goals.

由于居民使用柴火和能源匮乏，智利南部面临严重的空气污染。本研究通过对68户家庭的多维分析，结合社会人口调查、室内温度监测、住房类型及其改造评估，评估了科伊海克地区供暖改造政策的有效性。结果表明，低收入家庭每平方米能耗显著增加，但热舒适持续时间较短。虽然改造改善了室内温度，但它未能使家庭与污染燃料脱钩；值得注意的是，在62%的改造住宅中，由于根深蒂固的文化和经济因素，仍然使用柴火。调查结果突出指出，目前的政策，其特点是缺乏部际协调和标准化设计，未能解决中间城市的具体社会技术现实。我们的结论是，有效的去污需要从部门方法过渡到综合区域管理，使住房质量标准与当地能源转型目标保持一致。

Photovoltaic self-consumption (PVSC) has spread unevenly worldwide. In Ecuador, adoption remains lower than expected, and the influence of residential tariff design on PVSC profitability has received limited attention. This study examines how the increasing block pricing (IBP) tariff and net metering (NM) interact to determine the financial performance of residential PVSC in Ecuador. Full-year, high-resolution monitoring data from eight operational households were analysed. PV generation was scaled from 10% to 100% of annual demand and assessed under four scenarios: IBP with NM, IBP without NM, a fixed-price volumetric tariff with NM, and the same fixed tariff without NM. The results indicate that the IBP structure is the primary driver of profitability: under IBP with NM, the time to return on investment (TROI) is typically short for most households and can become exceptionally low for high-consumption ones. Removing NM reduces returns; however, under IBP, PVSC generally remains viable. In contrast, under a uniform volumetric tariff, NM becomes critical, as profitability deteriorates markedly in its absence. Overall, the findings help explain the uneven uptake of PVSC in Ecuador and highlight the central role of tariff design when deploying residential PVSC under regulated pricing frameworks.

光伏自用（PVSC）在世界范围内分布不均。在厄瓜多尔，采用率仍然低于预期，居民电价设计对PVSC盈利能力的影响受到的关注有限。本研究探讨了不断增加的大宗定价（IBP）关税和净计量（NM）如何相互作用，以确定厄瓜多尔住宅PVSC的财务绩效。分析了来自8个经营家庭的全年高分辨率监测数据。光伏发电量占年需求的比例从10%扩大到100%，并在四种情况下进行评估：有纳米发电的IBP、没有纳米发电的IBP、有纳米发电的固定价格容量电价和没有纳米发电的相同固定电价。结果表明，IBP结构是盈利能力的主要驱动力：在IBP与NM下，大多数家庭的投资回报时间（TROI）通常很短，对于高消费家庭来说可能会变得非常低。去除NM可降低收益；然而，在IBP下，PVSC通常仍然可行。相比之下，在统一的容量关税下，NM变得至关重要，因为在它缺席的情况下，盈利能力明显恶化。总体而言，研究结果有助于解释厄瓜多尔PVSC的不均衡吸收，并强调在受监管的定价框架下部署住宅PVSC时，关税设计的核心作用。

Liquefied Petroleum Gas (LPG) is a key clean cooking alternative to biomass, especially in developing countries where household air pollution remains a major concern. This study proposes a scalable decision-making framework for the design of LPG distribution networks, using Rwanda as a case study. We formulate a hierarchical location–allocation model as a Mixed-Integer Linear Program (MILP), leveraging a large-scale dataset with rooftop-level LPG demand for over 3.3 million households across Rwanda. To enable tractable, country-scale optimization, we adopt two complementary strategies: (i) a time-aggregated formulation assuming stable seasonal demand, and (ii) a spatial aggregation method based on agglomerative hierarchical clustering, which places retailers at distance-constrained geomedian points of rooftop clusters. We compare this clustering-based approach against a benchmark that uses village centroids for retailer siting, demonstrating cost savings and improved spatial fairness. Additionally, we assess the scalability of the system under projected demand growth and evaluate infrastructure–transportation trade-offs under fluctuating diesel prices. Our findings underscore the potential of data-driven planning tools in advancing equitable access to clean cooking solutions.

液化石油气（LPG）是生物质的关键清洁烹饪替代品，特别是在家庭空气污染仍然是主要问题的发展中国家。本研究以卢旺达为例，提出了一个可扩展的LPG分配网络设计决策框架。我们将分层位置分配模型制定为混合整数线性计划（MILP），利用卢旺达超过330万户家庭的屋顶液化石油气需求大型数据集。为了实现可处理的、国家尺度的优化，我们采用了两种互补的策略：(i)假设季节性需求稳定的时间聚合公式，以及（ii）基于聚集分层聚类的空间聚合方法，该方法将零售商置于距离受限的屋顶集群几何点上。我们将这种基于聚类的方法与使用村庄中心点进行零售商选址的基准方法进行了比较，证明了成本节约和空间公平性的提高。此外，我们评估了系统在预计需求增长下的可扩展性，并评估了柴油价格波动下的基础设施运输权衡。我们的研究结果强调了数据驱动的规划工具在促进公平获得清洁烹饪解决方案方面的潜力。

There is a lack of complete life cycle assessment (LCA) for solar electric vehicles (SEVs), particularly gaps in the quantitative analysis of synergistic effects between vehicle-integrated photovoltaic (VIPV) systems and power battery configurations. To address these issues, this study conducted a cradle-to-grave LCA of SEVs relative to battery electric vehicles (BEVs). Three interlinked models including life cycle carbon emission (LCCE) reduction, life cycle cost (LCC) increase, and energy consumption change were constructed, and four typical Chinese cities with distinct solar resource grades were selected for analysis. Key findings include: (1) SEVs significantly reduce the number of grid charges; for example, BEVs in Lhasa require 442 charges over 10 years, while SEVs only need 83 charges (81.2% reduction). (2) Power battery capacity reduction (20%–30%) balances environmental and economic benefits, and at 20% reduction (Lhasa) or 30% reduction (Chengdu), SEVs' LCC increase shifts from positive to negative. (3) Under similar numbers of charges, compared with BEVs, SEVs can reduce their power battery capacity by 50%–60%. (4) The LCC critical line (0 boundary) shifts upward with solar resource quality: at 25% VIPV efficiency, Lhasa tolerates an initial module cost of 500–600 CNY/m², while Chengdu only tolerates 200–300 CNY/m². Notably, improving VIPV efficiency has a weaker impact on LCC reduction than lowering initial module costs.

太阳能电动汽车（sev）缺乏完整的生命周期评估（LCA），特别是在车载集成光伏（VIPV）系统与动力电池配置之间协同效应的定量分析方面存在空白。为了解决这些问题，本研究进行了sev相对于纯电动汽车（bev）的从摇篮到坟墓的LCA。构建了全生命周期碳排放（LCCE）降低、全生命周期成本（LCC）增加和能源消耗变化3个相互关联的模型，并选取中国4个太阳能资源等级不同的典型城市进行分析。主要发现包括：(1)sev显著减少了电网收费数量；例如，拉萨市纯电动汽车10年充电次数为442次，而纯电动汽车10年充电次数仅为83次，降幅达81.2%。(2)动力电池容量减少（20% - 30%）平衡了环境效益和经济效益，在减少20%（拉萨）或30%（成都）时，sev的LCC增长由正向负转变。(3)在相同充电次数下，与纯电动汽车相比，纯电动汽车的动力电池容量可减少50%-60%。(4) LCC临界线（0边界）随着太阳能资源质量的提高而向上移动：在25% VIPV效率下，拉萨可承受的初始组件成本为500-600元/m2，而成都仅能承受200-300元/m2。值得注意的是，提高VIPV效率对降低LCC的影响要弱于降低初始组件成本。
