The analysis of 82 documents retrieved from Scopus reveals a notable increase in scientific production over the past six years, peaking in 2023 and 2024. This trend reflects the growing interest in sustainable energy solutions to address extreme climatic phenomena such as droughts. Among the most prominent research areas, climate change (29.27%), solar energy (26.83%), and renewable energies in general (25.61%) dominate the field, with a central focus on energy resource optimization and drought management. The keyword analysis confirms that solar and wind power are the most studied renewable energy technologies in drought-prone regions, emphasizing their potential to enhance energy resilience in vulnerable areas like Chile. The journal and citation network analysis indicate that the most influential publications are concentrated in journals such as _Applied Energy_, _Desalination_, _Renewable Energy_, and _Solar Energy_, which play a central role in disseminating research on climate adaptation strategies. The author collaboration mapping highlights the importance of international partnerships, with China and the United States of America leading in publications and cooperation networks. The co-authorship analysis further reveals that research efforts are increasingly globalized, with interdisciplinary teams working on optimizing hybrid renewable energy systems to mitigate the effects of drought and climate change. From a citation perspective, the most influential studies explore the potential of hybrid solar-wind systems, particularly in regions with limited water resources, and the application of renewable energy in rural and high-energy-demand sectors such as data centers. These studies emphasize the relevance of clean energy solutions in addressing both energy access and climate resilience challenges. The thematic evolution analysis further highlights a shift in focus from fossil fuels towards cleaner energy alternatives, as evidenced by the decline in publications on conventional energy sources. Solar energy in particular has gained increasing prominence since 2020, emerging as a key technology for mitigating the risks associated with megadroughts, especially in water-dependent economies like Chile. While this study provides valuable insights into research trends and collaborations in renewable energy strategies for drought mitigation, several limitations should be acknowledged:  
* The analysis is based exclusively on Scopus, which, although comprehensive, may exclude relevant studies indexed in other databases such as Web of Science or IEEE Xplore. * The search string used to retrieve documents inherently influences the results. Some relevant studies may not have been included due to variations in terminology or indexing practices. * The field of renewable energy is rapidly evolving. Future research may uncover emerging trends and technologies not fully captured in this dataset. In addition to these limitations, the findings of this study offer valuable insights for guiding future research and policy development. The results emphasize the need for further exploration of hybrid renewable energy systems, which play a crucial role in ensuring energy resilience in drought-prone regions. Moreover, the role of international collaborations is fundamental in fostering technological innovation and policy integration for a sustainable energy transition. The findings also suggest that emerging technologies, such as AI-driven energy optimization and hydrogen storage, could play a key role in addressing the challenges of renewable energy deployment under extreme climatic conditions.
