This study investigates the optimal selection of renewable energy technologies in Turkey through a combined multi-criteria decision-making (MCDM) framework that addresses both environmental sustainability and energy security within a context marked by rapid industrialization, substantial investments in wind and geothermal capacities, and a continued reliance on imported fossil fuels. In response to the global imperative to transition from unsustainable energy systems, the research introduces a novel integration of Hesitant Fuzzy Linguistic (HFL) Term Sets with the Simple Additive Weighting (SAW) method (HFL-SAW) to rigorously derive weights for a comprehensive set of criteria and sub-criteria essential to renewable energy selection. Building on this methodological foundation, the study employs three robust MCDM techniques, HFL Additive Ratio ASsessment (ARAS), HFL Multi-Attributive Border Approximation Area Comparison (MABAC), and HFL Evaluation based on Distance from Average Solution (EDAS), to comprehensively evaluate and rank competing renewable energy alternatives. This dual-level novelty which are methodological innovation and application to Turkey's evolving energy landscape distinguishes the study from prior research. The numerical results indicate that, based on the factor weights derived from HFL-SAW, SDG6 (Clean Water and Sanitation), SDG7 (Affordable and Clean Energy), and SDG13 (Climate Action) emerge as the most pivotal, underscoring the intrinsic interdependence between water security, sustainable energy production, and climate change mitigation. Comparative ranking thus reveals some variability among the methods, with hydropower energy systems consistently achieving superior rankings in both the HFL ARAS and HFL MABAC evaluations, and bioenergy and biomass systems are predominantly favored in the HFL EDAS assessment. The convergence of these findings not only substantiates the robustness and validity of the integrated analytical approach but also highlights the potential efficacy of hydropower and bioenergy solutions in facilitating Turkey's strategic energy transition. Furthermore, by systematically mapping each evaluation criterion to the corresponding United Nations SDGs, the study bridges the gap between renewable energy technology selection and global sustainability frameworks, offering valuable insights for policymakers tasked with formulating sustainable energy policies that foster economic growth, reduce environmental impacts, and enhance national energy security.
