Humanity has undertaken actions to decarbonize the main CO2-emitting industries, such as the energy industry. The solution to this problem has been to use renewable energy sources, with positive results in recent years. The objective of the present research was to analyze the scientific advances produced in research on renewable energy and energy production globally during the years 2019 and 2023. The purpose was to determine the current status and future trends in renewable energies in order to contribute to the scientific community by identifying potential risks and encouraging collaboration between authors, institutions, and countries. A bibliometric analysis was performed in the Scopus database using the keywords “renewable energies” and “energy production” within a search equation with a time limit of 2019 and 2023. Keyword co-occurrence and collaboration between authors and countries were performed with VOS Viewer software. It was determined, using per capita research analysis, that the leaders in this research were Cyprus, Denmark, Qatar, Norway, and Ireland. The leading institutions in this field of research are the Technical University of Denmark; Aalborg University; and the Ministry of Education, China. The predominant research topics were energy, engineering, and environmental sciences, related to energy sources such as biomass, hydrogen, or wave energy. The results described here have the potential to contribute to the scientific community, stimulating new research and identifying new needs in the existing literature.

Objective: To describe the characteristics of under-graduate theses, satisfaction and reasons for choosing a topic of study. Materials and Methods: Cross-sectional study that included two populations, theses and thesis students who were able to support their work from 2015 to 2021 in the Faculty of Dentistry of the Universidad Nacional Mayor de San Marcos (Lima, Peru). Documentary analysis was used at first to record bibliometric data. The survey was used in a second stage to collect information related to the reasons why the thesis students chose their topic and the degree of satisfaction. Results: A total of 269 theses were examined. The theses corresponded to more women (n=142; 52.8%). All had a quantitative approach. The cross-sectional/descriptive design was the most frequent (n=207; 77%). Of the 114 respondents, the majority of them indicated that their thesis topic decision was influenced by a faculty member outside of their advisor (n= 26; 22.8%). A total of 49.1% of thesis students were in complete agreement about what they had learned about research at the end of their thesis. Conclusions: The undergraduate theses evidenced to be developed mainly by women, most of the thesis students were satisfied with the elaboration and execution of their academic work; it was evidenced that the thesis topics are mainly influenced by a teacher different from the thesis advisor, this indicates that the advisors should be more conscious when guiding the student and influencing the thematic, methodological and writing decisions together with the advised. Keywords: Dental Students; Motivation; Academic Dissertations; Satisfaction.
