ABSTRACT
The paper attempts to examine the trend in renewable energy generation capacity in
Nigeria (2011 – 2020). The objective is
to have a better understanding of the generation of renewable energy of the study area. The renewable energy
sources considered include hydropower, solar energy, solar photovoltaic energy
and bioenergy. The assessment was carried out using statistics, trend analysis,
and regression models. Results showed that the hydropower energy sources
are the most utilized mode of power generation in the study area. It mirrors a
normal distribution with skewness = 0.267. The distribution curve for all the energy generation is
platykurtic as the numeric value of the kurtosis is less than 3. Also, the
highest growth rate of 45% is attributed to solar energy while the hydropower
generation has an insignificant growth rate of 0.047%. Finally, polynomial
regression model was observed to be the most appropriate model for predicting
hydropower, solar photovoltaic and bioenergy power sources while the
exponential model was suitable for the solar energy.
Keywords: Renewable energy, sustainable power, hydropower, solar energy, bioenergy
