Abstract

<p>This study examines the intersection of climate change and energy security in Nigeria, with a particular focus on the role of renewable energy solutions in addressing these challenges. Nigeria’ s heavy reliance on fossil fuels has made its energy sector vulnerable to climate-related disruptions and global market volatility. The research explores the current state of energy security, highlighting the nation’ s dependency on oil and gas, and identifies the vulnerabilities exacerbated by climate change, such as disruptions in hydropower generation and the degradation of oil infrastructure. The study also evaluates Nigeria's untapped renewable energy potential, including solar, wind, hydropower, and biomass, and emphasizes their critical role in diversifying the energy mix, reducing greenhouse gas emissions, and improving energy access. However, it identifies several challenges impeding the development of renewable energy, including policy and regulatory barriers, financial constraints, and inadequate infrastructure. The paper concludes with policy recommendations to foster the growth of renewable energy in Nigeria, such as strengthening policy frameworks, encouraging investment, expanding off-grid solutions, and enhancing technical capacity. The findings underscore the urgent need for a multi-dimensional approach to harness renewable energy for Nigeria’ s sustainable development, energy security, and climate resilience.</p>
