Bibliometric Analysis of Renewable Energy Research Trends Using VOSviewer: Network Mapping and Topic Evolution

Abstract

This article presents a bibliometric analysis of renewable energy research trends using VOSviewer software. The study aims to map the collaboration network between researchers, institutions, and countries and to identify the evolution of emerging topics in the field of renewable energy. The data is taken from leading scientific databases covering publications in recent years. The article uses network map visualisation techniques to reveal collaboration patterns and research distribution focused on critical themes like solar, wind, and bioenergy. In addition, the article analyses frequently occurring keywords, helping to identify emerging topic trends. The results of this study are expected to provide insights into the direction of future developments in renewable energy research and encourage increased international collaboration in the field.
