Abstract: Even though it is not yet certain how climate change will affect Nigeria, the recent changes in rainfall regime could be an indication of some of the challenges that we may face as we move into the 21st century. At present, the Nigerian economy is largely dependent on fossil fuel, which is one of the biggest contributors of CO2 to the atmosphere. This paper discusses the potential impacts of climate change in Nigeria in the 21st century and how renewable energy can be harnessed to mitigate or adapt to its effects. Various obstacles to achieving sustainable renewable energy in terms of policy, technical and financial barriers are enumerated and the strategies that could be adopted to overcome them are also discussed. The paper concludes that adopting clean technologies should be of utmost importance in domestic energy strategies and these should be supported by governments and other stakeholders.
