Abstract

The free energy market allows consumers to choose their electricity suppliers, unlikethe regulated market, where distribution is exclusive to local utilities. Companies andpublic agencies can purchase energy directly from generators or traders, reducing costsand adopting sustainable sources. This study presents a bibliometric analysis of the renewable energy market in public institutions from 1986 to 2023. Using the Web of Science database and VOSViewer software, 47 documents were analyzed to identify research trends regarding the number of publications, most cited journals and countries, and keyword co-occurrence. Between 1986 and 2010, the average number of annual publications ranged from 1 to 3, but after 2010, a significant increase was observed, with peaks in 2012, 2019, and 2020. Among the most cited articles are Herring (1999), Wade (2010), Helgesen (2018), and Pearce (2012). The citation analysis revealed thematic clusters, with the journals Global Policy, Applied Energy, and Energy Economics standing out. The co-authorship network indicated dispersed collaboration among 102 authors, with Hazboun Shawn Olson as the central author. The international analysis of countries showed 13 clusters, with the United States, the Netherlands, and Brazil leading in scientific production and collaboration. The keyword co-occurrence analysis identified 277 terms grouped into 5 clusters, with "Renewable energy" and "climate change" being the most frequent. The results suggest that the use of certain terms may have limited the search, creating a gap in study identification. Broader keywords are recommended to better explore the topic and increase the volume of available studies, promoting a more comprehensive understanding of the free energy market in public agencies.
