This paper aims to present an energy balance load sensitivity analysis and multi-criteria method for sizing a green energy system f...

Sub-Saharan Africa (SSA) is home to 75% of the world’s unelectrified population, and approximately 500 million of these live in rural areas. Off-grid mini-grids are being deployed on a large scale to address the region’s electrification inequalities. This study aims to provide a comprehensive review of the research on the off-grid renewable mini-gr...

This research study presents the design of a mobile Android application which provides efficient PV sizing recommendations for residential users. The paper aims to promote the adoption of solar energy to meet energy demands for residential use, by providing accurate information to prospective renewable energy users via the development of an android...

Globally, the quest to meet water demand and the continuous depletion of quality water have increased. Human existence and its sustenance are subject to the availability of water, particularly potable water. However, the possibility of attacks on the water systems, which are some of the critical infrastructures, has attracted interest of researcher...

The diversity of water pollution and the depletion of some water resources have continued to linger despite several governmental and non-governmental programmes, especially in developing countries for water quality sustainability. This problem has reduced potable water availability, and it has increased water-related diseases in these countries. Th...

It is crystal clear that appropriate technical sizing has a significant effect on the techno-economic analysis of an off-grid standalone energy system. As a result, this study presents the effect of incorporating the temperature coefficient in the optimal analysis of an off-grid hybrid system using a standard fuel (gas) station in Nigeria as a case...

The complexity of a water distribution network (WDN) allows human imposition where accidental or intentional attack is possible. These attacks sometimes result in the contamination of water that has been treated at the treatment plant, and can eventually, be consumed by the society. However, the use of contaminated water has gross negative public h...

Purpose This study aims to analyze the effects of variations in annual real interest rates in the assessment of the techno-economic feasibility of a hybrid renewable energy system (HRES) for an off-grid community. Design/methodology/approach Hybrid Optimization of Multiple Energy Resources (HOMER) software is used to propose an HRES for Abadam com...

The 2030 Agenda for Sustainable Development suggests that all countries both developed and developing strive to attain the seventeen sustainable development goals (SDGs). Some items on the SDGs like implementation of renewable energy technologies to electrify regions disconnected from power grids are targeted to eradicate extreme poverty and hunger...

Water contamination can result in serious health complications and gross socioeconomic implications. Therefore, identifying the source of contamination is of great concern to researchers and water operators, particularly, to avert the unfavorable consequences that can ensue from consuming contaminated water. As part of the effort to address this ch...

Without a doubt, petroleum-based resources have caused in increased interests in bio-renewable polymer-based, relatively cheap, readily available and environmentally friendly materials. These interests are growing in leaps and bounds and have and continue to elicit even greater interest in order to come up with new resources that are less unfavorab...

Protection of water distribution networks (WDNs) is at the forefront because of the negative implications of the use of the contaminated water on the public health. In order to safeguard the water distribution networks from accidental and intentional attacks, a water quality sensor should be installed across the network. Remarkably, the budget cons...

Presented in this study is an optimal hybrid renewable off‐grid energy system model that supplies a typical rural healthcare center across the six regions in Nigeria. A technical and economic evaluation was carried out to identify the optimal off‐grid hybrid energy system combination based on photovoltaic (PV), wind, diesel generator and battery. D...

The quest for sustainable energy has greatly increased across the globe. Erratic energy supply in many African countries restricts socioeconomic growth, particularly in developing countries. Besides, the depletion of fossil fuel and the environmental threats caused by the use of conventional energy supply is a challenge that requires immediate atte...

There are over 50,000 telecommunication base transceiver stations (BTS) operating on conventional diesel generators across Nigeria, giving rise to a high operational cost and emission of Greenhouse gases which can be minimized by the adoption of greener energy generation. Presented in this study, is an analysis of the techno-economic and emission i...

Protection of the water system is paramount due to the negative consequences of contaminated water on the public health. Water resources are one of the critical infrastructures that must be preserved from deliberate and accidental attacks. Water qualities are examined at the treatment plant. However, its quality can substantially be contaminated du...

Background Simultaneous measurements of air temperature were carried out using automatic weather stations at 14 tropical locations in Nigeria. Diurnal variations were derived from the 5-minute update cycle initial data for the years ranging between 2007 and 2013. The temperature trends in Nigeria revealed a continuous variability that is seasonally...

Changing temperature is a major climatic concern, and its temporal variations affect activities such as agriculture, which is the major economic activity in north-central Nigeria. We present preliminary results on the use of artificial neural networks to model temporal surface temperature variations recorded at Tropospheric Data Acquisition Network...

The seasonal and diurnal variations of solar radiation have been studied by analyzing two years data measured at the ground surface in a tropical wet and dry climatic region and the guinea savanna station Anyigba (7.486N, 7.1836E), in Nigeria using Campbell automatic weather station. The analysis was carried out over two years with each year divide...
