Lawal, Lateef Ademola2025-05-182009-07http://repository.futminna.edu.ng:4000/handle/123456789/1999Research ArticleThe importance of energy in the built environment cannot be over-emphasised. in Nigeria, energy is being supplied to every home and built up areas through fossil fuels and hydro systems. The supplies of energy through these systems are not only unreliable but also have inherent dangers associated with their use with attendant pollution of the environment. Despite this shortcoming, most countries of the world ironically, still continue to rely on these sources for their energy supply. This paper seeks to explore other renewable sources of energy that can be used in the built environment. It examines solar energy as a veritable alternative for Nigeria because of the abundance supply of sunlight in the country, which has not been optimally utilised. It presents the experiences of countries in Africa and North America who have adopted the use of solar energy in their various communities. The paper gives suggestions toward ensuring adequate and affordable electricity in the built environment.enBuildingEnergyEnvironmentRenewableSolarArticle
