Analysing the Impact of Human Capital on Renewable Energy Penetration: A Bibliometric Reviews

Abstract

In contributing to reducing the adverse effects of non-renewable energy sources, this paper researched how human capital can enhance the penetration level of renewable energy, which is highly abundant in Nigeria, Sub-Saharan Africa. This paper, using qualitative research methodology through Bibliometric analysis, reviewed three hundred and three (303) papers published between the year 2000 and March 2022. The bibliometric study covered publications per author, publications per country, research focus based on co-occurrence keywords, and research thread. The findings revealed that publications on how human capital can aid renewable energy penetration have been slow and in an infant stage in the past two decades. It also shows that there have been eighteen (18) papers on the subject papers in the last twenty years, showing the low level of human capital development in the energy sector. The intellectual patterns via the co-occurrence of keywords shows five (5) clusters, which are economics of renewable energy sources, human capital factors in environmental management, economic factors in energy supply and demand, sustainable energy factors, and human capital development and economy. These cluster areas revealed how human capital could be developed to increase the penetration level of the abundant renewable energy in the world. Thus, this paper recommends intensive efforts in optimizing human capital through inter-organizational collaboration on renewable energy technologies and periodic training.
