A state-of-the-art review on readiness assessment tools in the adoption of renewable energy

The goal for a sustainable tomorrow has been in focus for quite some time. The significance of renewable energy in achieving that goal is unavoidable. The necessity for transitioning toward a diverse energy portfolio with renewable energy sources has been established for a low-carbon future. The collective efforts rapidly deploying clean energy sources at multiple levels, from self-consumption facilities to large-scale renewable energy harnessing projects, have been widely encouraged as a social responsibility. The significance of measuring the effectiveness of the put-forth attempts through policies and initiatives is an undebatable fact. This paper attempts to comprehend the existing assessment tools and related literature on the prevalent systems for assessing renewable energy adoption readiness of a country or a region through a systematic literature review. The most relevant published literature was identified with a methodological framework and summarized to understand the explored angles of the research area. The research also makes an attempt to investigate the annual trend in the publication and contributions of authors, affiliations, journals, and articles in the published literature through bibliometric analysis using the “bibliometrix” package of the R Studio platform. The analysis also outlines the trends of the topics of research, methods, and analysis tools used in the field of study, and various approaches used to explore different scenarios. The summarized collection of articles emphasized the role of interdisciplinary research areas in determining the status of a region in the clean energy transition and the relevant need for addressing challenges at multiple scales.
