Energy Performance Contracting (EPC) is increasingly used as a financial mechanism to accelerate renewable energy investments in public infrastructure; however, its effectiveness depends not only on technical performance but also on institutional governance arrangements. This study evaluates a 1.71 MWp grid-connected photovoltaic (PV) system implemented under an EPC model at a public university in Türkiye, examining the interaction between operational performance and institutional governance structures. A mixed-methods research design was applied, combining SCADA-based electricity generation data for the 2024–2025 monitoring period with contract analysis and institutional evaluation. The results indicate that the PV system achieved stable electricity production levels and an average performance ratio of approximately 83%, demonstrating reliable operational performance under real operating conditions. Annual electricity generation reached about 2.13 GWh in 2024 and 2.44 GWh in 2025, corresponding to estimated carbon emission reductions of approximately 895 and 1025 tonnes of CO₂, respectively. Despite these technical achievements, the analysis reveals several governance-related challenges, including fragmented institutional responsibilities and limited transparency in monitoring and verification processes. The findings suggest that the effectiveness of EPC mechanisms depends on the integration of technical performance monitoring with coherent institutional roles and transparent governance structures. When supported by clear policy alignment and systematic monitoring frameworks, EPC-based photovoltaic investments can function as effective instruments for accelerating renewable energy deployment and supporting decarbonization strategies in public sector institutions.

Bu çalışma, Türkiye’nin demokratikleşme aşamalarında asker-sivil ilişkilerine yönelik tarihsel arka plandan hareketle demokrasinin konsolidasyon sürecini incelemektedir. Özellikle 15 Temmuz askeri kalkışmasına kadarki süreç, Türkiye’de ordunun siyasete doğrudan müdahale ettiği darbeler dönemini demokrasi tarihi bakımından üzücü birer vaka olarak göz önüne serer. Bu bağlamda askerlik mesleğinin iç ve dış tehditlere karşı devleti koruyan hiyerarşik otonom bir güç oluşu, demokratik temayüllerin ve kanuni tanımların yetersizliği nedeniyle siyasetin gündemiyle anılmasına neden olmuştur. Demokrasinin sivilleşme çabaları dikkate alındığında Türkiye’de söz konusu durum, sıklıkla ordu-siyaset ilişkisini anti-demokratik ilişkiler boyutuna taşımıştır. Dolayısıyla 15 Temmuz sonrası yapılan kanuni düzenlemelerle sivil denetim faaliyetinin önemi artmış ve yargı birliği sağlanarak, ordu-siyaset ilişkisinin demokratik şekilde konsolide edilebilmesinin önü açılmıştır.

The localization of the Sustainable Development Goals (SDGs) has become a central dimension of sustainable urban development, as local governments play an increasingly important role in translating global sustainability agendas into place-based action. This study aims to provide a state-of-the-art assessment of how scholarly research has examined the relationship between local governance and SDG implementation over the period 2018–2025. A mixed-method review approach was employed, combining bibliometric mapping using VOSviewer with qualitative content analysis conducted through NVivo. Based on predefined inclusion criteria, 143 peer-reviewed articles indexed in the Web of Science database were systematically analyzed. The results reveal several dominant thematic clusters, including institutional coordination, sustainable urban planning, data-driven governance, accountability mechanisms, and the growing use of policy tools such as Voluntary Local Reviews (VLRs). The findings indicate an increasing emphasis on performance-based monitoring, participatory governance approaches, and multilevel institutional frameworks supporting the integration of the SDGs into local policy and planning processes. At the same time, persistent challenges are identified, particularly with regard to equity considerations, data inconsistencies, and the limited inclusion of marginalized urban communities in SDG-related decision-making. Overall, this review offers a structured and comprehensive overview of current research on SDG localization in urban governance and identifies key gaps and priorities for future research and policy development aimed at more inclusive, measurable, and context-sensitive pathways to sustainable urban development.

Türk iktisadi hayatının yükseliş ve çözülüş dinamikleri üzerinde duran Sabri Ülgener, gerek batılı düşünürlerin yorumları gerekse geçirdiğimiz tarihsel süreçten hareketle İslâm toplumlarını iktisadi hayatını anlamlandırmaya çalışır. Türk toplumunun 16. Yüzyıldan beri geri kalmışlığının sebepleri üzerinde duran Ülgener, batılı yorumcuların aksine, dinin Türk toplumunun gelişiminde önemli bir yere ait olduğu görüşünü savunur. Türk sanatını, kültürünü, siyasetini belirleyen İslâm’ın aynı zamanda iktisadi hayatını da belirleyen önemli bir norm olduğu, medeniyetin yükselişi ve inhitatında bu normun önemli bir yer edindiğini vurgular. Bu bağlamda insanı “homo econumicus” yani ekonomik bir varlıktan ibaret olarak gören modern iktisadi yaklaşımlardan uzak, insana mânâ vazifesi yükleyen, insanın ekonomik durumunu da dinî ve kültürel referanslarla anlamlandıran bir iktisadi yaklaşımı önceler. Bu durum toplumların düşüncesi dünyasındaki farklı algılamaların ürünüdür.

This study conducts a multi-dimensional evaluation of Energy Performance Contracts (EPCs) applied to solar photovoltaic (PV) systems in public institutions, emphasizing their technical efficiency, governance structure, and policy accountability. Within the broader context of solar resource utilization and sustainable energy transition, EPCs are increasingly recognized as strategic mechanisms to enhance energy efficiency and reduce emissions without imposing immediate fiscal burdens on public budgets. Using a mixed-methods approach, the research integrates quantitative assessments of photovoltaic system performance—based on SCADA-verified production data and CO₂ mitigation outcomes—with qualitative evaluations of contract design, stakeholder coordination, and institutional transparency. The case of a 1710.72 kWp university-based PV installation in Türkiye demonstrates that EPCs can effectively deliver high operational reliability (performance ratio: 83%) and substantial environmental benefits (1168.64 tons of CO₂ avoided annually). However, the study also reveals that EPC success is critically shaped by the coherence of regulatory frameworks, administrative capacity, and accountability mechanisms. Institutional fragmentation, limited data integration, and insufficient governance oversight remain significant barriers to scaling EPC adoption in the public sector. The research concludes by proposing an integrated policy framework that aligns technical performance monitoring with transparent governance and policy coherence. This approach supports real-time performance tracking, multi-level coordination, and enhanced institutional accountability—key enablers for accelerating the solar energy transition through scalable and financially sustainable EPC models in public infrastructure.
