Energies and Its Worldwide Research

Abstract

Energy efficiency and management is certainly one of the key drivers of human progress. Thus, the trends in the energy research are a topic of interest for the scientific community. The aim of this study is to highlight global research trends in this field through the analysis of a scientific journal indexed exclusively in the energy and fuels category. For this purpose, a journal has been selected that is in the center of the category considering its impact factor, which is only indexed in this category and of open access, Energies of the publisher MDPI. Therefore, a bibliometric analysis of all the contents of the journal between 2008 and 2020, 13,740 documents published, has been carried out. Analyzing the articles that are linked to each other by their citations, 14 clusters or research topics have been detected: smart grids; climate change–electric energy community; energy storage; bioenergy sources; prediction algorithms applied to power; optimization of the grid link for renewable energy; wind power; sustainability of power systems; hydrocarbon improvements; conversion of thermal/electrical energy; electric motor advancements; marine renewable energy; hydropower and energy storage; and preventive techniques in power transformers. The main keywords found were electric vehicle, renewable energy, microgrid, smart grid, and energy efficiency. In short, energy research remains necessary to meet the future challenge of sustainable energy with high efficiency and the exploration of new renewable resources, all for increasingly sustainable cities.

The Journal Buildings: A Bibliometric Analysis (2011–2021)

“…The whole process of bibliometric analysis of the journal is illustrated in Figure 1. The different application fields of bibliometric analysis include civil engineering and management [5], automation in construction [6], energy [7], road and bridge engineering [8], transport [9], etc. Particularly, it is interesting to publish special issues or papers to celebrate the significant anniversary of a journal.…”

“…Note that in the literature, it has become the norm to develop bibliometric research since it provides scholars with realistic and objective statistics and analysis, enabling researchers to build a comprehensive knowledge and understanding of the research field. The different application fields of bibliometric analysis include civil engineering and management [5], automation in construction [6], energy [7], road and bridge engineering [8], transport [9], etc. Particularly, it is interesting to publish special issues or papers to celebrate the significant anniversary of a journal.…”

Solar Energy Technology: Step Towards Bright Future of the World

“…In nine main fields of solar energy sustainable development, 11,848 writers from 131 countries are working (Novas et al, 2021). Europe has 4080 researchers, the most of any continent, whereas Africa has the least contribution in the field of research, with several countries making no contribution at all (Garcia et al, 2020;Novas et al, 2020). With the use of two multi-criteria techniques (Streimikiene et al, 2012), a decision support framework was built to select the most sustainable energy technology, demonstrating that renewable energy sources should be selected to meet energy demand.…”

Advances in Solar Energy towards Efficient and Sustainable Energy

“…Within Europe, Italy is the country that contributes the most with 6.77% of the total, the largest contribution in Asia is made by China with 8.59% and in America the greatest contribution is made by the United States. The map shows that the African continent is where there is a greater concentration of countries that do not contribute with any researcher on this subject, as happens in other publications such as [7,8].…”
