The dynamic relationships between nuclear energy consumption, nuclear reactors and load capacity factor: time and frequency domain panel data analysis

Abstract

Nuclear energy is an environmental issue that needs to be carefully considered regarding its consequences. The environmental effects of nuclear energy encompass a complex interplay of factors, ranging from managing radioactive waste to the potential for accidents, emissions, and resource depletion, necessitating a thorough examination of its impact on our planet. This study examines the relationships between nuclear energy, nuclear fission, nuclear fusion, and load capacity factor for the eight countries (Canada, China, France, Germany, Japan, Russia, Spain, USA) that consumed the most nuclear energy from 1993 to 2018 using the time (Emirmahmutoglu & Kose, 2011) and frequency domain (Croux & Reusens, 2013) panel causality tests. The results differ according to time and frequency domain causality tests. While the time-domain causality test results showed no causal relationship between the nuclear energy consumption, nuclear reactors, and the load capacity factor variables, the frequency-domain causality test revealed that there are causal relationships between these variables in the short, intermediate and long run. According to the frequency-domain causality test results, there is a bidirectional causality relationship between nuclear reactors, energy consumption and load capacity factor. In line with the main findings of this study, it is recommended that these countries implement effective policies to increase environmental quality and make investments and incentives in nuclear energy and technologies.
