Modeling the Next Decade of Energy Sustainability: A Case of a Developing Country
No full textThe development of any country is closely related to its ability to provide access to electricity for productive labor. Many countries in sub-Saharan Africa have low electrification rates for commercial, industrial and residential consumers. This study focuses on Nigeria, which has one of the largest populations and economies in sub-Saharan Africa. Although Nigeria possesses abundant renewable energy resources that can increase electricity generation, it has suffered a significant setback in electricity generation. However, for Nigeria to become one of the leading industrialized countries by 2030, access to clean, reliable, and sustainable energy sources is vital (Vision 20: 2030). This study assesses the possibility of Nigeria developing and transitioning to the use of various energy sources. Additionally, this study evaluates greenhouse gas (GHG) mitigation plans and future trends in energy sustainability through multi-criteria decision analysis (MCDA), considering the technical, social, economic, and environmental dimensions of the sustainability structure. A total of twelve (12) sustainability indexes were taken into consideration; these consist of two (2) technical, three (3) social, three (3) environmental, and four (4) economic indicators. A scenario-based software called Long-range Energy Alternative Plan (LEAP) was used to integrate the analysis criteria and forecast a sustainable energy generation mix for the future. It considered three scenarios, namely: the business as usual scenario (BAU); renewables, natural gas and biomass scenario (RNB); and renewables and coal scenario (REC). It was concluded that the renewables, natural gas, and biomass scenario (RNB) is the best scenario to solve Nigeria’s energy problem based on the aim of the study
Holistic review of agricultural wastes used as supplementary cementitious materials in cement-based materials
No full textConcrete is the most consumed construction material owing to its vast applicability, durability, and low cost. However, the carbon footprint of cement, the main binder in concrete, is concerning. Hence, the need for low-carbon substitutes is urgent. Agricultural waste materials that can serve as supplementary cementitious materials have been identified as a possible option. In this chapter, a holistic overview of the characteristics, properties, and performance of agricultural waste materials serving as supplementary cementitious materials in cement-based materials, such as mortar and concrete, is presented. Agro-waste materials covered are sugarcane bagasse ash, rice husk ash, corn-cob ash, palm oil fuel ash, paper pulp ash, groundnut husk ash, bamboo leaf ash, coconut shell ash, cassava peel ash, and wood/sawdust ash. The performance of cement-based materials at optimum content is presented. If the agro-wastes are well processed, they could serve as supplements for cement in cement-based materials with comparable performance to the control concrete mixture.</p
Artificial Neural Network and Particle Swarm Optimization for Medium Term Electrical Load Forecasting in a Smart Campus
No full textEnergy demand has continued to increase rapidly not exempting Covenant University. As the university continues to witness infrastructural expansion and population increase, it has become a necessity for energy consumption to be predicted. Hence, this research work developed a medium-term load forecasting system to solve this problem and ensure an efficient electricity supply from the power system operators of Covenant University. The forecast was carried out on real-time monthly load data collected from the university community power plant between 2015 and 2018, using the Artificial Neural Network (ANN) model. A medium-term load forecast was evaluated based on three different ANN algorithms. The FeedForwardNet, Cascadeforwardnet and Fitnet are tested against three (3) different learning algorithms namely Levenberg Marquardt, Bayesian regularization and BFGS quasi-Newton backpropagation with a particle swarm optimizer. And the network performance was obtained using Normalized Root Mean Square Error (nRMSE %). The result revealed an nRMSE of 0.0634%, a correlation coefficient, r, of 0.9082 and the fastest computation speed of 171.789 seconds. Hence, this study provides a point of reference for other related studies and future energy forecast improvement in the study location

Performance evaluation of the prospects and challenges of effective power generation and distribution in Nigeria
No full textEffective Electric Power Generation and Distribution result in the overall increase in efficiency in
an economy. Nigeria generates 4500 MW for a population of 200 million people; hence, more
than 50% of the population has no electricity access, and those with access experience power
outages. Inasmuch as Nigeria is blessed with a vast amount of renewable energy sources, the
country heavily relies on Natural Gas for power Generation. With regards to Power Generation, it
is seen that the Power Generated is not evacuated efficiently. The purpose of this study is to access
the growth of the Nigerian Power Sector from 1898 till date. This is achieved by evaluating the
Power Sector Reforms enacted by different government to analyze their effectiveness. Furthermore,
the study reviews strategically research that have discussed the strengths and weakness of
the Nigerian Power Sector to be able to suggest hidden opportunities and reveal threats to the
attainment of sustainable energy for all in 2030. Some of the Challenges discovered were energy
user challenges, financial challenges, and energy losses. Some solutions and opportunities are the
use of distributed generation, smart meters and the implemented of a smart grid system. In the
long run, the authors propose that viable renewable energy sources in each State of the federation
be tapped for Power Generation this would enable each State to the self-reliant and contributors
to the Nigerian Power Generation Pool. It is believed that this actions would promote economic,
social and technological benefits for the every stakeholder
