The demand for electricity generation around the world has significantly increased over the past decades, this is due to the growth in the world’s population, industrialization, economic activities and technological innovation; with various countries opting for alternative sources of renewable energy sources to replace the use of fossil fuel sources of energy whose availability has rapidly declined. The Nigeria power sector has experienced a major setback in power generation, distribution and the power consumption rates in the country has been very low compare to other African countries in electricity per capita. This study examines the designing of an affordable solar photovoltaic (PV) system in Nigeria using the cost and benefit method. Furthermore, a proposed PV electrification model was designed to calculate the Financial Internal Rate of Return (FIRR), Net Present Value (NPV) and Sensitivity analysis of installing a mini-grid system within the Federal Capital Territory (FCT). The result however showed that the system efficiency was calculated as FIRR was 17.5% and the NPV was at N320,897,841 which suggest that the project on this scale is economically viable in the FCT, making the life cycle cost per kWh, including the grid extension cost relatively low. Furthermore, the result obtained revealed that electricity generated from solar energy can contribute to the country’s economy and also eliminate or cut the pollution and toxic waste from the burning excess fossil fuel that releases large amount of CO2 into the atmosphere which affects human health and the environment.

The study analyzed the relationship between parent socioeconomic status and child malnutrition in Nasarawa State, Nigeria, with a particular emphasis on the pathway through which the socioeconomic factors of the parents determine child nutrition and wellbeing. To achieve this objective, a study was conducted in the Lafia metropolis with a random sample of 480 women who had children between the ages of 0 to 5. Data analyzed was collected by administering a structured questionnaire to women in the study area. Descriptive statistics, chi-square, and mediation analysis were employed to analyze the data. The findings from the results unveiled that the primary determinant of child nutrition in Nasarawa State is the mother’s educational status. Furthermore, the mediation analysis showed a perfect mediation between the mother’s Education, toilet facility, and child malnutrition. The study recommended that the government should encourage sensitization on the importance of girl child education at all levels, especially among rural dwellers. Having quality education by the girl child will improve her socioeconomic status through an increase in Education and a rise in income level to better her role as a future mother.
