Scientometric Analysis of Renewable Energy Investment: Examination of Patterns and Key Topics
Keywords:
Renewable Energy Investment, Scientometrics, Energy Policy, Sustainable Development, Network AnalysisAbstract
This study conducts a scientometric analysis of renewable energy investment (REI) with the aim of identifying major patterns and key thematic areas within this field. Given the growing importance of renewable energy in addressing environmental challenges and achieving sustainable development, the research investigates scientific trends related to investment in renewable energy. The research adopts a descriptive design and utilizes data indexed in the Scopus database covering the period from 2000 to 2025. A systematic search strategy was implemented to retrieve relevant publications, including the identification of appropriate keywords, their combination using Boolean operators, and a rigorous screening process of the retrieved documents. Ultimately, 1,123 articles were selected as the final statistical population. The findings indicate a significant increase in the number of publications over the past two decades, with China and the United States emerging as leading contributors in this domain. Keyword co-occurrence analysis revealed that concepts such as “investment,” “renewable energy,” “energy policy,” and “sustainable development” hold central positions and are frequently addressed in the scientific literature. The study also emphasizes the importance of institutional and policy interactions in renewable energy investments and provides a foundation for future research in this field. In particular, the results can assist researchers, policymakers, and investors in developing more effective strategies for sustainable development and renewable energy investment by improving understanding of prevailing trends and existing challenges.
