Utilization of renewable energy sources is a major topic as energy demands increase and conventional energy sources continue to deplete. Consequently, the quantity of scholarly articles on the topic of hybrid renewable energy systems (HRESs) has increased during the past two decades. This article presents a bibliometric analysis on the topic of HRES using statistical analysis and analysis of publication characteristics to provide a thorough overview of research advancements and trends from 2004 through 2021. The results of a total of 1003 Scopus databases retrieved on February 22, 2022, show that the number of HRES theme publications is increasing year after year. VOSviewer, Rstudio Biblioshiny, Microsoft Excel, and Tableau Public were used to obtain the results of bibliometric analyses of the most prominent authors, number of citations, country productivity, and journals that publish HRES publications. Eltamaly, A.M., is the author with the most publications on this HRES topic, while Maleki, A., has the most citations. India is the most productive country, and Iran is the most cited country in this research theme. Collaboration between countries is also very dominant. In terms of journals, the "Renewable Energy" journal is the primary reference journal for this topic, having the biggest number of publications and h-index relative to other journals. Empirical researchers can use this article to see how study subjects change from year to year and how HRES research themes are changing.
