Abstract. This article focuses on the influence of climate change on energy consumption in Ireland. The purpose is to conclude this influence and give the Irish energy companies a better understanding of energy production. All the data sources were collected from the official websites of the Irish government. The article chose several climate factors such as wind speed and temperature etc. This paper especially concentrates on electronic power consumption. All these data were transformed into a monthly form. The author used linear regression models to analyse the relationships between climate factors and Energy consumption. The R studio is one of the most important tools for this research. The author creates many kinds of linear models to fit the data accurately. The main discovery of the research is that temperature has the most significant influence on energy consumption. They have a strong linear relationship. The Irish government might need to manage electricity production based on the temperature change to fit the citizens' needs and avoid risks of severe climate conditions in the future.
