Implication

Randomized trial evaluates renewable energy choices in Istanbul, indicating wind energy as the top option.

Key Points

This study aims to evaluate renewable energy sources by addressing complexities in decision-making using a novel analytical framework.
Employs spherical fuzzy sets to capture uncertainty in expert evaluations.
Utilizes a distance-based mechanism for comparison in spherical fuzzy environments.
Integrates I-SF-SWARA and I-SF-PROMETHEE for ranking renewable energy alternatives.
Wind energy ranked first with a net outranking flow value of 1.5978, followed by solar energy at 1.5717.
Technological complexity (0.1723), technological maturity (0.1605), and reliability (0.1379) were identified as key influencing criteria.
