The growing demand of electric power supply in Nigeria necessitates the integration of renewable energy resources into the country’s energy mix which is in consonance with the global energy transition. This paper is an attempt to theoretically evaluate the potential of human waste (faeces) for the electrification of a modest residential building (3-bedroom flat) with six occupants. The daily electrical energy demand of the building is estimated to be  while the daily electrical energy value of the biogas produced by the excreta of the six occupants is. This shows that the daily quantity of excreta of the six building occupants is inadequate to meet the daily electrical energy demand of the building. Therefore, hybrid system should be employed if the building is to be effectively electrified. Individuals and government at all levels are implored to embrace this emerging technology because of its potential of not only generating biogas for electricity generation or cooking, but also for fertilizer production, protection of the environment and mitigation of sanitation problems.
