India's electricity requirements will continue to grow with its increasing population and urbanization. Climate change, increased carbon emissions, and the depletion of nonrenewable energy resources have forced India to shift to renewable energy resources. India's solar potential is large enough to provide 100-percent of its current electricity requirements if photovoltaic arrays and energy storage infrastructure of sufficient size is deployed. In this paper, we modeled the dynamics of net electricity input and output from a photovoltaic electricity (PV) system as it is built out to provide the entire electricity demand by 2050. The results showed that building a PV system large enough to meet the nation's entire electricity demand by 2050 is possible; however, it will require a rapid increase in the deployment of solar PV and the associated storage infrastructure over the next few decades. Such rapid expansion of the PV system will require substantial electricity allocation away from general societal use and towards building the photovoltaic system equipment and integrating it with existing infrastructure. This will lead to a short-term lack of electricity supply for general use by society. [ABSTRACT FROM AUTHOR]

Electricity is the basic tool that drives industrialization, technological advancement, engineering transformation and economic growth all over the world. The situation of Nigeria's electricity power sector is one that has defied virtually every effort made to resurrect it from its state of dilapidation. A major concern is “can there ever be stable and cost effective electricity in Nigeria?” The authors are positive this can be realised, but not without considering other forms of electricity energy resources available in Nigeria other than the conventional sources of electricity which is currently the mainstay. A deliberate transition from conventional sources of electricity energy to renewable and environmental friendly sources is critical for national development, even though recent development show the Nigerian government is backsliding in adopting renewable energy technologies. This paper will be used to highlight the different sources of renewable energy which is critical to solve the lingering problem of electricity generation in Nigeria. Hence, based on the literature, modeled scenarios and field experience, the authors discovered it is much easier for individuals to drive this transition to 100% renewable energy than to continue to depend on government forever.
