1.0 Introduction
1.1 Background of the Study
All living things depend on energy for survival, and modern civilizations will continue to thrive only if existing sources of energy can be developed to meet the growing demands, hence Energy is “Life” Energy is“Existence”, it is the dividing line between the rich and the poor, between the developed, developing and the underdeveloped (Ohunakins et al., 2011). For a country to grow beyond its subsistence economy, tackle the problem of poverty, the country will need to have minimum access to energy services for the larger proportion of its population (Ohunakins et al., 2011). However, in Nigeria energy supply has been epileptic in nature, causing the socio-economic status of the country to be downgraded (Ohunakins et al., 2011).
Nigeria's energy demand increases with an increase in population, but power supply has remained unreliable and insufficient with a country generation capacity of about 3500 MW as at 2011 (Okeke, 2011). Nigeria as a nation has started feeling the impact of adverse climate change, that may be attributed to the overdependence on fossil fuel fired power plants which is the main source of greenhouse gas emissions (GHG), coupled with activities of manufacturing industries, oil prospecting firms and deforestation, to mention but a few.
Renewable energy (RE) has been identified as the only alternative of addressing these problems. RE is energy derived from an energy source that can generate itself through natural processes within a relatively short period; unlike fossil type resources that take millions of years to form and which is not regenerative.
