Finding Sustainable Countries in Renewable Energy Sector: A Case Study for an EU Energy System

Abstract

This study aims to identify sustainable countries within the European Union in terms of renewable energy. The objective is to support renewable alternatives and enhance sustainability in the renewable sector among the top economic countries. The study reviews key drivers of sustainable development, establishes criteria for each dimension, and selects up-to-date indicators. The fuzzy analytical hierarchy process and expert judgments are employed to rank the countries, ensuring unbiased results, and reducing uncertainty. The findings indicate that Sweden, Belgium, Ireland, France, Germany, Spain, the Netherlands, Poland, and Italy exhibit their positions from the most advanced to the lower sustainable countries, respectively. Energy and environmental indicators play a primary role as the most influential drivers. Economic factors contribute as tertiary drivers, while social and institutional indicators have a relatively minor influence. Notably, Sweden, Belgium, and Ireland, despite being among the last three in terms of economic ranking, emerge as the most sustainable countries in renewable energy, surpassing stronger economies such as France, Germany, and Spain. On the other hand, the Netherlands, Poland, and Italy, as middle economy countries, rank lower in terms of sustainability. These results provide insights for harnessing renewable energy in high-growth economies and offer valuable policy advice for implementation.

Rationalization of Electrical Energy Consumption in Households through the Use of Cheap IoT Module with Cloud Data Storage

“…Coal-fired power facilities are the predominant source of electricity in Poland, resulting in a relatively low ranking in the EU sustainable development economy [31]. However, the share of RES in Poland's electricity production has been steadily increasing for many years.…”

Do Green Energy and Information Technology Influence Greenhouse Gas Emitting Countries to Attain Sustainable Development?

“…In the climate change space, significant policies that have been encouraged and advised in recent years to reduce greenhouse gas (GHG) emissions have focused on enhancing clean energy [1,2]. The primary drivers of these policies are the extreme levels of CO 2 emissions triggered by intensive non-renewable energy (NRE) in the overall energy mix [3,4]. Over 80% of the energy consumed worldwide comes from non-renewable sources [5].…”
