Renewable Energy Sources and Energy Production: A Bibliometric Analysis of the Last Five Years

Abstract

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.

Impact of the Structural Parameters on the Performance of a Regenerative-Type Hydrogen Recirculation Blower for Vehicular Proton Exchange Membrane Fuel Cells

“…The growth rate in the number of automobiles globally has raised concerns about the growing environmental pollution and energy crisis [1]. To this end, in view of the large demand for fossil fuels in conventional internal combustion engine vehicles, as well as the problems of atmospheric pollution and the greenhouse effect [2], some countries have taken action to reduce carbon emissions for realizing global energy sustainability [3]. As a result, there is an urgent need for the exploitation of other alternative sustainable energy sources.…”

Latin America towards Sustainability through Renewable Energies: A Systematic Review

“…Since industry and transportation depend on fossil fuels, there is an increase in the demand for energy [2], as well as the generation of CO 2 emissions and other pollutants that increase the global temperature of the planet and the environmental problems by seriously affecting vegetation, crops, the balance of ecosystems and fauna. In this context, all organizations worldwide have made efforts in recent years to protect and safeguard the environment by signing agreements and treaties to regulate the use of pollutants and the amount of harmful emissions and to curb the environmental impact of human activities [3,4]. This is reflected in the creation of accords such as the Paris Agreement by the United Nations, with the objective of mitigating climate change and considerably reducing global temperatures, in addition to accelerating investments and actions for a more sustainable future [5].…”

Assessment of Wave Energy Converters Based on Historical Data from a Given Point in the Sea

“…Renewable energy is one of the cornerstones of sustainable human development, with solar, wind and sea waves being the most popular due to their high energy capacity, although the latter is very far from achieving its exploitation objectives [1]. Within this field, wave energy has some important advantages, especially due to the continuous availability of the source, all day and year-round, and to its low environmental impact compared to other energy sources, since it does not generate emissions or pollution during its operation [2].…”
