Abstract

This study addresses the fragmentation of research on technological innovations for the integration of renewable energy in smart cities, addressing the lack of systematic mapping of trends and knowledge gaps. To this end, a bibliometric analysis of scientific production (2018–2025) was conducted using a Boolean search strategy in databases, analysis in RStudio and VOSviewer to map keyword co-occurrences, collaborative networks, author and journal metrics, and an author–term–source Sankey diagram. The results revealed three clusters: one focused on "clean energy," "renewables," and "artificial intelligence"; another on "sustainable development," "energy policy," and "smart grids"; and an emerging cluster on "energy production." The collaboration map placed India as the main node, connected to China, Germany, and the US. Among the authors, Abed AM stood out with 167 citations, followed by Alsharif MH (26), Brent AC (9), Kumar P and Nedungadi P (8 each). The journals Energies and Energy Reports led the way with 34 and 32 publications. The Sankey diagram illustrated knowledge pathways between researchers, topics, and sources, highlighting specialization and collaborative opportunities. These findings offer a roadmap to guide policies and foster interdisciplinary collaboration for more sustainable cities.
