    Developing Sustainable Renewable Energy for Rural Dwellers' Energy Sufficiency
    (ABUAD Journal of Engineering Research and Development (AJERD), 2017) Ajibola, Olawale Olaniyi Emmanuel; Ibidapo-Obe, Oye; Balogun, Oluwaseyi Jessy
    The issues connected with the worldwide growth in energy consumption, energy conservation, and finding environmentally benign ways of energy production may arguably be the most significant challenge facing mankind in the 21st century. Government policies on rewarding economic goals have failed due to inadequate supply of energy. A strong energy sector is essential for a vibrant and competitive economy. Whilst we proceed with increasing the energy generation capacity, transmission and distribution of existing energy from traditional sources through the development of energy systems that enhance social, economic and environmental performance; it is appropriate to focus on renewable and sustainable energy forms for rural areas. In this paper, we explored various renewable and sustainable energy options, namely: solar, wind, micro hydro, fuel cells and bio fuel; with the aim of proposing an environmental friendly and cost effective option that will ultimately solve the energy crisis both in rural and urban areas in Nigeria. Our methodology is purely empirical with data drawn from a pilot project carried out on a household in Magboro community, a suburb of Lagos. The result of the work revealed that the solar system based on photovoltaic cells is a viable renewable energy solution to the perennial power failure especially to the rural populace in Nigeria. The ultimate aim of this paper is to provide the springboard for the development of an enduring energy policy in Nigeria.

    Experimental Investigation of Energy Potentials of Kitchen Organic Waste
    (Journal of Engineering Research, 2016-12) Ajibola, Olawale Olaniyi Emmanuel; Fagbamila, TT; Balogun, Oluwaseyi Jessy
    In sub-Sahara Africa, kitchen wastes (KWs) are worthless product that are disposed freely on open refuse sites causing environmental pollution and aiding the spread of pathogenic diseases. With increasing population, demand for energy is constantly on the rise. Persistent rise in prices of fossil fuel products often result in shortage in supply of energy for both domestic and industrial applications in most developing nations. To solve the imbroglio created by the shortfall of energy, renewable energy can be explored: one viable source of such is the biomass. However, KWs have very high Carbon Nitrogen ratio (C: N) of 35: 1. The preceding statement then implies that if co-digested in appropriate ratio with human faeces and allowed to degrade inside an anaerobic digester, KWs have a disposition to drastically reduce the problems of inadequacy in energy supply. In this paper, the slurry obtained from KW, human excreta (HE) and water (W) was anaerobically digested in batch digesters A, B and C under mesophilic conditions in ratio 5: 1: 6, 1: 1: 2 and 1: 5: 6 respectively. The results obtained were analyzed to determine the slurry with the highest biogas yield. The digester with label A has the highest yield of 8164 mL of biogas as against digesters B and C which produced 7060 mL and 2307 mL respectively from the same volume of slurries. This is attributable to the higher ratio of kitchen waste in digester A. The result obtained from this study is expected to promote a better understanding of biogas technology
