Abstract
The global biofuels have attracted a lot of attention because of their potential as a clean and renewable source of energy. The bibliometric method has been used for providing quantitative assessment of the field of biofuels research in South Africa. Data used in this study were obtained from Scopus database. The research covers such topics as the publications and citations, the document type, journals, leading authors, institutions, subjects, areas and keywords. The publications and citations data fitted the Gompertz model to find out the growth rate. Two stages in the evolution of publications and citations were found and coincide with the exponential behaviour. Biofuels research was identified to have an exponential growth from 2011 with a growth rate of 0.2628 years-1 (R2=0.93). This study demonstrates that the most documents were published in high-impact journals. Researchers would benefit from the findings because they would be able to see a trend in biofuels research in South Africa.Keywords: Bioethanol, biogas, biofuel, biodieselJEL Classifications: Q16, Q20, Q42DOI: https://doi.org/10.32479/ijeep.11454
Highlights
The primary cause of anthropogenic greenhouse gas pollution is fossil fuels
Researchers conducted on South African institutions has covered a wide range of biofuels and it is necessary to assessment the evolution of publications to determine the potential of the scientific community and the pertinence of public policy
The following section explicitly describes the results of the bibliometric analysis of the 352 documents found, published from 1979 to 2020 on the biofuels field in South Africa
Summary
The primary cause of anthropogenic greenhouse gas pollution is fossil fuels. As a society, we need solutions for good food security and environmental quality. Excise tax exemptions and incentives, clean or low carbon fuel requirements, fiscal incentives, and public financing have been developed and introduced to promote the production of biofuels (Ebadian et al, 2020). In this context, South Africa has developed a number of policies aimed at promoting the production and use of biomass fuels, as well as attracting investment into rural agricultural growth and creating new jobs, but biofuels have yet to be commercially generated in large quantities (Pradhan and Mbohwa, 2014). A bibliometric analysis can provide information on the growth trends and characteristics of research outputs
