The Nuclear Dilemma : A Study on the Nuclear Energy Growth Nexus and Greenhouse Gas Emissions

Detta är en Master-uppsats från Linköpings universitet/Nationalekonomi; Linköpings universitet/Filosofiska fakulteten

Sammanfattning: The relationship between energy consumption and economic growth has been a popular topic in recent studies, with a considerable amount of literature conducted, although there still is no consensus regarding the relationship. Few studies have analysed the nuclear energy growth nexus with greenhouse gas emissions, and none have used the same method, data, and sample period. Therefore, there are still gaps in the literature regarding the Energy Growth Nexus, and this study provides a unique insight into the Swedish nuclear dilemma.   The purpose of this paper is to study the causal relationship between economic growth and nuclear energy consumption, and the causality between greenhouse gas emissions and nuclear energy consumption, in Sweden. The results of which are used to discuss the future consequences a continued shutdown of Sweden’s nuclear power could have. Seven EU nations and two non-EU nations are included to be able to make comparisons to Sweden. This paper is based on a method of time series analysis by conducting Ordinary Least Squares-regressions in combination with Granger causality tests.    Our results indicate that nuclear power granger cause growth in Belgium and the United Kingdom. Additionally, this study finds a bidirectional granger causality between greenhouse gas emissions and nuclear energy in the USA. The causal relationship between nuclear energy, economic growth, and greenhouse gas emissions in Sweden is still unclear. However, the Swedish energy market is facing multiple challenges including global warming, increased energy demand, and a transition towards a completely renewable energy mix. The role of nuclear power in the Swedish energy mix is still unclear. It is therefore the authors belief that a decision regarding the future of the Swedish energy supply is needed.
