Abstract:
Nigeria is the seventh most populous country in world being the highest in Africa. The country is blessed with vast natural resources and is one of the highest producers of oil in the world. However, the inadequate supply of electrical energy is a major setback in the nation\'s economic development. Thus, there is need for an urgent and immediate solution to address the electricity access situation in Nigeria. It is in view of this that we first present an overview of the electrical energy situation of Nigeria (especially in the rural areas). The benefits of rural electrification and it impacts are discussed to buttress the need for electrifying rural areas and an overview of the abundant renewable energy resources in Nigeria is presented. As a proposed solution to improve the electricity situation, the concept of a reuse solar photovoltaic system based on e-waste components and old materials is presented. The system comprises repurposed Power Supply Unit (PSU) from old desktop computers, old thermal car Lead-acid batteries, old solar panels and Uninterruptible Power Supply (UPS) units. The possibility of adopting this solution in Nigeria depends on the amount of e-wastes generated annually thus necessitating the need for an analysis to see the annual impact of this system on electricity access based on the amount of available e-waste. Using the huge amount of e-waste generated/received annually in Nigeria, the feasibility of our solution is assessed by estimating the possible number of households that could be electrified by the second life renewable energy systems we propose. Due to the lack of official data in this field, certain constraints and assumptions were defined for the purpose of this analysis which resulted in obtaining a range of results that showed the possible impacts of adopting the reuse system. The analysis showed the minimum and maximum impacts the reuse solution could have on electricity access in Nigeria, based on best and worst case scenario respectively. The results further showed that an average of 287,000 households can be electrified annually if this solution is adopted, causing 2.2 % increment in population with electricity access in a year (between 620 thousand and 4.1 million individuals). Thus, the result is an indication that it is possible to achieve immediate growth in electricity access based on renewable energy integration, frugal innovation and reuse/repurposing of e-waste materials. In addition, this extension of their lifespan reduces their ecological footprint. It is expected that the energy demands of the continuously growing population can be met by strict adherence to set targets including adoption of smart-grids, generation diversification and focusing on rural electrification.
摘要:
尼日利亚是世界上人口第七多的国家,也是非洲人口最多的国家。该国拥有丰富的自然资源,是世界上最高的石油生产国之一。然而,电力能源供应不足是国家经济发展的重大挫折。因此,有必要采取紧急和立即的解决方案,以解决尼日利亚的电力接入情况。鉴于此,我们首先概述了尼日利亚(特别是在农村地区)的电能状况。讨论了农村电气化的好处及其影响,以支持农村地区电气化的需求,并概述了尼日利亚丰富的可再生能源资源。作为改善电力状况的解决方案,提出了基于电子垃圾组件和旧材料的再利用太阳能光伏系统的概念。该系统包括从旧台式计算机重新利用的电源单元(PSU),旧的热汽车铅酸蓄电池,旧的太阳能电池板和不间断电源(UPS)单元。在尼日利亚采用这种解决方案的可能性取决于每年产生的电子废物的数量,因此需要进行分析,以根据可用电子废物的数量来查看该系统对电力访问的年度影响。利用尼日利亚每年产生/接收的大量电子垃圾,我们的解决方案的可行性是通过估计我们提议的第二生活可再生能源系统可能实现电气化的家庭数量来评估的。由于缺乏这方面的官方数据,为了本分析的目的,定义了某些约束和假设,从而获得了一系列结果表明采用重用系统可能产生的影响的结果。分析显示,再利用解决方案可能对尼日利亚的电力接入产生的最小和最大影响,分别基于最佳和最坏的情况。结果进一步显示,如果采用这一方案,平均每年可实现28.7万户家庭通电,导致一年内用电人口增加2.2%(62万至410万人)。因此,结果表明,在可再生能源一体化的基础上实现电力接入的即时增长是可能的,节俭的创新和电子垃圾材料的再利用/再利用。此外,它们寿命的延长减少了它们的生态足迹。预计通过严格遵守设定的目标,包括采用智能电网,可以满足持续增长的人口的能源需求。发电多样化,专注于农村电气化。
