Endowed with abundant renewable energy resources, Nigeria stands at a pivotal point in its energy development journey. This study explores the landscape of renewable energy policy and legislation in Nigeria, highlighting the challenges and opportunities that shape the sector. The research begins with an overview of Nigeria's current energy framework, emphasizing the critical role of renewable energy in achieving sustainable development. It examines existing policies and legislative frameworks, identifying the key government agencies responsible and outlining their respective functions. Despite the country's vast potential, numerous barriers impede the growth of renewable energy. These include legal and regulatory inconsistencies, institutional inefficiencies, financial constraints, and technical challenges. The study delves into these issues, providing a comprehensive analysis of how they hinder progress in renewable energy adoption. Conversely, the research identifies significant opportunities to enhance renewable energy policy and legislation including potential legislative reforms, institutional strengthening, financial incentives, and the promotion of technological innovation and infrastructure development. By leveraging these opportunities, Nigeria can create a more robust and conducive environment for renewable energy growth. The study concludes with strategic recommendations for policymakers and stakeholders to bridge the existing gaps and foster a sustainable energy future for Nigeria. It also outlines future research directions aimed at optimizing renewable energy policies and practices. Through this comprehensive analysis, the study aims to contribute to the ongoing discourse on renewable energy in Nigeria, providing insights to guide effective policy-making and legislative action.
