Energy Inequality Indicators: A Comprehensive Review for Exploring Ways to Reduce Inequality

Abstract

Society faces challenges in achieving a climate-neutral society due to deepening energy inequality. The pandemic led to reduced emissions but also caused an economic downturn. Geopolitical tensions since 2022 raised energy prices, affecting affordability. To address these issues, this research aims to conduct a systematic literature review to explore the content, conceptualization, and distinguishing factors of energy inequality compared to similar concepts as well as to identify energy inequality dimensions and its indicators and explore ways to reduce it. A systematic literature review explored recent publications on energy inequality from 2019 to 2023, encompassing both pre-pandemic and pandemic-affected periods. This review analyzed 203 articles, with 61 of them directly focusing on energy inequality indicators. This research is conducted in several stages. Firstly, this article clarifies the concept of energy inequality and highlights its differences from related terms. Secondly, this study investigates the effects of energy inequality taking into account its diverse dimensions, and it categorizes these dimensions and their respective indicators based on their specific contexts. Thirdly, recommendations are provided for potential approaches to reduce energy inequality. The methodology integrates an examination of macroeconomic energy inequality statistics. The resulting findings hold the potential to significantly contribute towards cultivating a more environmentally conscious trajectory. Moreover, these outcomes play a pivotal role in advancing energy justice and effectively tackling the multifaceted challenges posed by energy inequality.
