Thematic Structure of Renewable Energy Integration in Sustainable Development

Abstract

The purpose of this study is to analyze the thematic structure of renewable energy integration, identify development
patterns, and propose a research roadmap for BRICS nations in renewable energy sector. The research uses
bibliometric analysis to achieve an aim of the research. The keywords utilized "Renewable energy," "Sustainable
development," "Digitalization," "Green energy," and "Social and Economic development," which were employed to
retrieve relevant research from the Scopus database. The core collection of Scopus yielded 448 renewable energy
research articles published between 1994 and 2023, which were analyzed using the bibliometric analysis program
in VOS viewer. The findings revealed that the keywords that performed best were "energy" and "renewable," with
circles denoting related topics. Nearly, 58.3% of the 448 papers from 1439 different authors were included in the
study. The most fruitful co-authorships were those that connected the top ten writers of the paper. The findings also
revealed that the challenges like high costs, technological hurdles, and regulatory barriers persisted in the renewable
energy sector.
