Abstract

The more frequent meteorological anomalies and climate changes push us to consider green sustainable energy as a chance to slow down such issues. Thus, we should introspect the correlations between indicators over time and understand the underneath of their meaning. Large volumes of data regarding energy are provided by Eurostat and other official data sources that require data analytics to extract valuable insights from energy indicators and indices to better understand the dynamics towards a green energy transition of the European Union State Members (EU-SM). In this paper, we analyze several energy indicators calculated for a 12-year time span with statistics and machine learning techniques, such as an unsupervised clustering algorithm with Self-Organizing Maps (SOM). Grouping the EU-SM by energy indicators from the beginning years to the end of the analyzed interval reveals differences and similarities in their efforts, shifted trends, influencing power and tendencies towards a green energy transition. The results of our analyses can be further used to assess the efficiency of stimuli for green energy generation and improve the policymakers’ strategies.

Highlights

In contemporary society, green energy generation became a necessity, because of the evermore higher pressure, to conform to environmental requirements
OBTAINED FROM CORRELATION ANALYSIS Before we proceed with the correlation analysis, we perform some preliminary tests to verify the assumptions needed in the described methods
We found a strong positive correlation between the implicit tax rate on energy and energy productivity

Summary

Introduction

Green energy generation became a necessity, because of the evermore higher pressure, to conform to environmental requirements. In the fight against climate change, the modern economy must adapt and be oriented towards those sustainable energy sources which can offer certainty in provisioning and a low impact on the environment. Green energy production is a growing industry these days. Imperatives such as continuous climate change and general population health issues related to air pollution are restrictive. Other power generation means, such as nuclear power, have a public perception problem related to near-past large-scale accidents, and a higher cost problem. Many states and other state-like entities, such as the EU, have large-scale policies for supporting green energy production [1]
