Existing literature has revealed both positive and negative impacts of solar photovoltaic (PV) from the viewpoints of engineering design, energy system's stability, environment, and socio-economic aspects. However, little has been known about solar PV's multi-dimensional impacts on resilience of local farmers and fishermen under climate change. To fill this gap, this paper assessed the kinds of positive and negative impacts on resilience that could be generated by land- and water-based solar systems and how various policies could be harmonised to synergise solar energy diffusion, resilience, adaptation, and more broadly, sustainable development. Laguna Lake watershed in the Philippines which is planning the installation of large-scale floating solar PV was selected as a case study site, where focus group discussions were held and the participants' perceived impacts of solar PV were measured. The results suggested that both land- and water-based solar PV were perceived as providing relatively larger co-benefits compared to the potential risks with regards to farmers' income, climate adaptability and green development level including water saving and greenhouse gas emission (GHG) reductions. Both types of solar PV have large co-benefits in the productivity of intermediate inputs, network marketing of agricultural products, production value, infrastructure, and eco-environment, while water saving and GHG emission reduction are unique co-benefits of land-based solar PV. Impacts on sustainable development goals (SDGs) of both types of solar are non-negligible for ending poverty (SDG 1), ending hunger (SDG 2), education (SDG 4), gender equality (SDG 5), economic growth and employment (SDG 8), climate actions (SDG 13) and global partnership (SDG 17). Based on these findings, a generic conceptual framework consisting of drivers, policies, actions, local enabling conditions, and outcomes for climate and sustainable development was suggested, which showed how to synergise mitigation and adaptation for the purposes of sustainable development in a just or equitable manner by enhancing local enabling conditions or resilience through a combination of climate and non-climate policies.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"88 ","pages":"Article 101812"},"PeriodicalIF":4.9,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145018283","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study addresses that gap using competitive tender prices and detailed PVsyst performance simulations from six recently commissioned grid-connected hybrid systems in Trinidad and Tobago (2–10 kW PV; 15–30 kWh storage). Results highlight pronounced economies of scale, with system size expansion from 2 kW to 10 kW reducing the levelised cost of electricity (LCOE) from US$0.694/kWh to US$0.191/kWh (−72 %) and levelised cost of storage (LCOS) from US$0.284/kWh to US$0.186/kWh (−34 %). Marginal abatement costs simultaneously decrease from US$211 to US$66 per tonne CO₂, reflecting substantially improved environmental returns with increased system scale. Lead-acid batteries offer lower upfront costs; however, lithium-ion storage approaches cost parity at system capacities of 5 kW or greater due to superior cycle life and utilisation characteristics. Despite these improvements, the resulting costs remain significantly above global benchmarks, highlighting structural economic and logistical challenges specific to SIDS contexts. Key policy recommendations include aggregating rooftops into optimally sized installations (8–10 kW), deploying targeted green financing mechanisms, and introducing dual-rate net billing tariffs coupled with storage rebates. Implementing these policies can significantly reduce unit costs, narrowing the gap with global benchmarks, and provide a replicable framework for sustainable renewable energy deployment and carbon mitigation in SIDS.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"88 ","pages":"Article 101818"},"PeriodicalIF":4.9,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144988461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using qualitative content analysis (QCA), the study systematically analyzed relevant laws and guidelines issued by government agencies. A set of codes corresponding to social sustainability categories was applied to identify patterns and potential gaps. Key findings reveal six prominent social sustainability categories, including energy access (emphasizing full electrification); socio-economic benefits and employment (highlighting financial benefits and affordable electricity); involvement and governance (enhancing stakeholder participation in policy decisions); social development, well-being, and quality of life (addressing environmental concerns); social equity (focusing on distributive and procedural aspects); and health and safety (prioritizing public health and pollution mitigation). Underrepresented categories, such as social acceptance, gender, human rights, and education, indicate policy gaps that warrant further integration. This study advances theory by introducing a coding framework that identifies social sustainability dimensions from national energy policies. It also offers practical value by providing empirical insights to enhance policy inclusivity and a transferable approach for similar assessments in other national contexts, particularly in developing countries.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"88 ","pages":"Article 101817"},"PeriodicalIF":4.9,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144931773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its adoption in developing countries faces significant barriers. Existing studies have significantly analysed barriers to cooking energy and technology, but have overlooked those specific to induction cooking. Moreover, no comparative analysis using multiple multi-criteria decision analysis (MCDA) models has assessed the robustness of different tools. Past studies also mainly rely on expert opinions only, often neglecting household perspectives. This study identifies and ranks the primary barriers to induction cooking adoption in Nepal, based on the perceptions of both experts and households. Drawing on literature review and expert consultations from academia and non-governmental organisations, 21 barriers were identified and grouped into five categories. These barriers were prioritised separately by 47 experts and 220 induction stove user households. Experts compared the barriers using the Saaty scale, and their inputs were analysed through the Analytical Hierarchy Process (AHP) and Fuzzy Analytical Hierarchy Process (FAHP). While both methods rank alternatives based on expert judgements, FAHP incorporates fuzzy logic to better capture uncertainty and human subjectivity. Meanwhile, households prioritised barriers using ranking-based frequency analysis. Sensitivity analysis showed FAHP to be the most effective decision-making tool compared to AHP due to stable and reliable rankings. FAHP-based expert rankings revealed the economic criterion as the most influential category, with poor electrical wiring/metering ranked as the top barrier by 51.19 % of experts. Conversely, household rankings indicated improper peak load management as the most critical barrier, cited by 38.6 % of respondents. Both groups highlighted technical barriers as a significant challenge to the adoption of induction cooking.
