Impact Analysis of Renewable Energy based Generation in West Africa – A case study of Nigeria
Get PDFThe limited supply of fossil fuels, constant rise in the demand of energy and the importance of reducing greenhouse emissions has brought about the adoption of renewable energy sources for generation of electrical power. In this paper, the impact of renewable energy generation in Nigeria is explored. A review of renewable deposits in Nigeria with a focus on Solar, Biomass, Hydropower, Pumped Storage Hydro and Ocean energy is detailed. The impact of renewable energy-based generation is assessed from three different dimensions: Economic Impact, Social Impact and Environmental Impact. In accessing economic impact; the conditions are employment and job creation, gross domestic product (GDP) growth and increase in local research and development. To analyze the social impact; renewable energy education, renewable energy businesses, ministries and institutes, renewable energy projects and investments as well as specific solar and wind projects across Nigeria were considered. Also, environmental issues were discussed. Similarly, policy imperatives for renewable energy generation in Nigeria was provided. This paper would be useful in accessing the successes Nigeria has experienced so far in the area of sustainable development and the next steps to achieving universal energy for all in Nigeria in 2030.Ograniczona podaż paliw kopalnych, stały wzrost zapotrzebowania na energię oraz konieczność ograniczenia emisji gazów cieplarnianych pociągnęły za sobą konieczność stosowania odnawialnych źródeł energii do wytwarzania energii elektrycznej. W artykule zbadano wpływ wytwarzania energii odnawialnej w Nigerii. Szczegółowy przegląd zasobów energii odnawialnej w Nigerii, ze szczególnym uwzględnieniem energii słonecznej, biomasy, energii wodnej i elektrowni szczytowo-pompowych i energii oceanicznej. Produkcja energii ze źródeł odnawialnych została przeanalizowana w trzech różnych wymiarach: wpływ na gospodarkę, wpływ na społeczeństwo i wpływ na środowisko. W aspekcie wpływu na gospodarkę wzięto pod uwagę: zatrudnienie i tworzenie miejsc pracy, wzrost produktu krajowego brutto (PKB) oraz wzrost lokalnych badań i rozwój. Analiza wpływu społecznego objęła: edukację w zakresie energii odnawialnej, przedsiębiorstwa, ministerstwa i instytuty zajmujące się energią odnawialną, projekty i inwestycje w zakresie energii odnawialnej, a także konkretne projekty dotyczące energii słonecznej i wiatrowej w całej Nigerii. Omówiono również kwestie środowiskowe. W podobny sposób przedstawiono imperatywy polityczne dotyczące wytwarzania energii odnawialnej w Nigerii. Ten artykuł wskazuje na istotny dla Nigerii cel zrównoważonego rozwoju, jakim jest odnawialna energia dla wszystkich. Celem jest osiągnięcie w tym kraju powszechnej odnawialnej energii dla wszystkich w 2030 r
Modeling the Next Decade of Energy Sustainability: A Case of a Developing Country
Get PDFThe 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
Get PDFEnergy 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
