“…Olaoye et al (2016) opine that the use of 1000 W solar power systems on rooftops of one million Nigerian homes will result in a cumulative power production of 7000 MW of which can translate into a 45% addition to the present electricity per capita consumption. Several PV-related studies have been conducted in Nigeria including: solar energy potentials (Fadare, 2009;Okoye et al, 2016;Giwa et al, 2017;Ikejemba & Schuur, 2016); solar energy related policies ; environmental footprints of electricity generation from solar PV (Akinyele et al, 2017); and technical and or economic feasibility related study of solar PV-systems (Bukar et al, 2017;Njoku et al, 2016;Okoye & Tylan, 2017;Adaramola & Oyewola, 2014;Ajoa et al, 2011;Adaramola, 2014;Oparaku, 2002;Akpan et al, 2013). From the aforementioned studies, it could be gathered that Nigeria has a good solar potential which could be harnessed to allay the energy crisis of the country and reduce GHG emissions.…”

The development and use of solar photovoltaic (PV) technologies worldwide is considered crucial towards fulfilling an increasing global energy demand and mitigating climate change. However, the potential of a solar PV-system is location specific, influenced by the local solar resource, energy demand and cost among other factors. The main aim of this study is to conduct a detailed assessment of the potential of solar PV-systems in residential buildings in Lagos Metropolitan Area, Nigeria. Nigeria has enormous solar energy potential, it is the most populous country in Africa and occupies a significant place in the development of Africa. Yet, it is a county with one of the lowest per capita electricity consumption in the world-at 149 kWh per capita for a population of about 170 million, about 7% of Brazil's and 3% of South Africa's. To achieve this goal, this study employed the survey of 150 residential buildings in three local government areas (LGAs) in Lagos State, Nigeria to obtain electric load data. HOMER Pro was used to size the PV-systems and to determine the levelized cost of electricity (LCOE). The computed energy results of the study for the base case scenario revealed the PV array, lead acid 2 battery and the converter (inverter) of the PV-systems to be in the following range: 0.3 to 76 kW; 2 to 176kWh; and 0.1 to 13.2 kW respectively. Economic analysis revealed a LCOE of the systems in the range of 0.398 USD/kWh to 0.743 USD/kWh. The use of PV-system generated electricity in the dwellings has potential for an annual reduction of greenhouse gas emissions in the range of 31.24 kgCO2eq to 7456.44 kgCO2eq. Clearly, the use of solar PV systems in residential buildings possesses potentials for enabling Nigeria to attain its climate change mitigation targets indicated in her National Determined Contributions (NDCs).

“…The outlined challenges are ascribed to inadequate electric power generation and overreliance on seasonal hydroelectric dams and gas-fired turbines (Musa 2010; Odior and Oyawale 2012). Other prominent challenges include distribution losses due to old or lowefficiency transmission infrastructure, and the rising spate of power-cable vandalism (Oparaku 2002;Oseni 2011). Hence, the problem of inadequate power generation needs to be urgently addressed through diversification of the nation's energy mix, which currently comprises hydropower, natural gas, and biomass (Oyedepo 2012b;Oyedepo 2014).…”

In this study, the physicochemical, microstructural, mineralogical, thermal, and kinetic properties of three (3) newly discovered coals from Akunza (AKZ), Ome (OME), and Shiga (SHG) in Nigeria were examined for potential energy recovery. Physicochemical analysis revealed high combustible but low levels of polluting elements. The higher heating values (HHV) ranged from 18.65 MJ/kg (AKZ) to 26.59 MJ/kg (SHG). Microstructure and mineralogical analyses revealed particles with a rough texture, surfaces, and glassy lustre, which could be ascribed to metals, quartz, and kaolinite minerals. The major elements (C, O, Si, and Al), along with minor elements (Ca, Cu, Fe, K, Mg, S, and Ti) detected are associated with clays, salts, or the porphyrin constituents of coal. Thermal analysis showed mass loss (M L ) ranges from 30.51% – 87.57% and residual mass (R M ) from 12.44% – 69.49% under combustion (oxidative) and pyrolysis (non-oxidative) TGA conditions due to thermal degradation of organic matter, vitrinite, inertinite and liptinite macerals. Kinetic analysis revealed that the coal samples are highly reactive under the non-isothermal oxidative and non-oxidative conditions based on the Coats-Redfern Model. The activation energy ( E a ) ranged from 23.81 kJ/mol – 89.56 kJ/mol whereas the pre-exponential factor ( k o ) ranged from 6.77×10 -04 min -1 – 1.72×10 03 min -1 under pyrolysis and combustion conditions. In conclusion, the coals are practical feedstocks for either industrial applications or energy recovery.

“…Research has been ongoing in the area of life cycle cost analysis of different renewable energy systems and conventional energy sources. Refs [5][6][7][8][9][10] affirmed the need for the adoption of solar energy as alternative energy systems. Software and different simulation tools have been developed and employed in life cycle cost analysis of alternative power generation systems [11,12].…”

The human and economic development of any nation is largely tied to the availability of energy, hence the need for an adequate supply of electricity by reliable energy systems. Nigeria’s economic growth is undermined by the epileptic nature of its electricity supply system. Consequently, the populace is forced to turn to alternative sources of power. However, this presents another problem - conflict of choice between available options for power generation. There is, therefore, the need to assist electricity consumers in Nigeria make better and cost-effective choices in this regard. In this paper, a software computer program is developed to determine/compare life cycle cost (LCC) of solar photovoltaic (PV) and diesel generator systems as preferences for electricity generation in Nigeria. The software is developed through an approach involving load determination, energy resources determination, system sizing and a typical residential building. The key methodology adopted is evolutionary prototyping which focuses on vertical dimension approach. Typical load description of a household located in Amawbia Awka of Anambra state in Nigeria was used to test the efficiency of the source code. The initial cost and life cycle cost for the two systems over a period of 30 years was ascertained. The test results showed the solar PV system to be a more cost-effective solution than the diesel generator based on total life cycle costs. The study recommends among others, the need to increase awareness of the long-term benefits of solar energy systems as an alternative source of electricity in Nigeria.
