The global energy transition is pivotal in mitigating climate change. In Chile, the system that includes hydropower faces challenges from prolonged megadroughts, necessitating diversification toward renewable sources like solar and wind energy. However, research gaps persist understanding how these can optimally address climate-induced vulnerabilities. This study conducts a bibliometric analysis to identify trends on strategies under extreme drought conditions, distinguishing it systematic or narrative reviews. A was conducted using Scopus, incorporating 82 selected documents analyzed via Bibliometrix VOSviewer map co-authorship networks, keywords, publications. Results revealed significant increase (26.83%) (25.61%) within period (2005–2024), with most notable growth occurring last six years. Key findings include predominance of studies optimization, technologies emerging as for enhancing resilience water-scarce regions. These insights underscore strategic role energies addressing vulnerabilities while supporting sustainable transitions. implications this work lie guiding future policy frameworks enhance security environmental sustainability.
