This study explores the relationship between renewable energy adoption and digitalization in the sector, reviewing literature from 2010 to 2022. The research aims to identify the current use of digital technologies, challenges to adoption, and future prospects. Key search engines (SCOPUS, Web of Science, and Google Scholar) were used to locate relevant papers, resulting in 69 articles for analysis. The findings highlight the significant role of digital technologies in supporting renewable energy, with high costs and security risks being major challenges. Most papers are optimistic about the future but recommend further R&D. The integration of digital technologies into renewable energy is driven by sustainability and sustainable development, extending beyond energy demand. The study contributes to the literature by considering the broader picture of the coupling between digitalization and renewable energy, focusing on critical areas. The small sample size (69 out of 856 hits) underscores the need for more in-depth research. The integration of digital technologies, such as blockchain and IoT, is advancing globally, with solar and wind power being the most discussed renewable energy sources. Challenges include technological security, high costs, and regulatory frameworks. Addressing these challenges holistically with a focus on sustainability can facilitate a smoother and more resilient energy transition.This study explores the relationship between renewable energy adoption and digitalization in the sector, reviewing literature from 2010 to 2022.
