This review synthesizes the burgeoning intersection of digital transformation and human resource management (HRM) within Nigeria’s renewable energy sector. The research aims to elucidate how digital technologies are reshaping HR practices and strategies, and to what extent these changes are influencing the sector’s growth and sustainability. Employing a systematic literature review methodology, the study aggregates findings from peer-reviewed journals, industry reports, and case studies pertinent to the Nigerian context. The review reveals a significant shift towards automation and data-driven decision-making in HR functions, including recruitment, training, performance management, and employee engagement. It also highlights a growing emphasis on strategic HRM to foster a workforce agile enough to adapt to digital innovations. Key findings suggest that while digital transformation presents opportunities for efficiency gains and competitive advantage, it also poses challenges related to workforce digital literacy and the alignment of HR strategies with technological advancements. The implications of this study are twofold: it offers a roadmap for HR practitioners in the renewable energy sector to navigate the digital landscape effectively, and it provides policymakers with insights into the necessary frameworks to support the sector’s digital transition. The review concludes with recommendations for future research, particularly the need for empirical studies to validate the identified trends and strategies in the Nigerian renewable energy context.
