Promotion of renewable energy and energy efficiency in Nigeria will address the challenges highlighted above.

Solar electricity may be used for power supply to remote villages and locations not connected to the national grid.
For these deployments one, two or more modules can be situated on a structure for it to provide the necessary electrical energy for the running of the basic lightning needs of the village household.
It has been reported that an average annual wind speed of not less than 5 m/s at a height of 10m above ground level is the feasible speed for the exploitation of wind energy at today’s cost.
In recent studies carried out in twelve states and four river basins, over 278 unexploited SHP sites with total potentials of 734.3 MW were identified.
The availability of biomass resources follows the same pattern as the nation’s vegetation.
Reference Growth Scenario:
- GDP growth of 7% p.a
Optimistic Growth Scenario:
- GDP growth of 11.5% p.a
High Growth Scenario:
- GDP growth of 10% p.a
Energy Demand and Supply Projections The Energy Commission of Nigeria recently worked on the energy demand and supply projections in Nigeria. Their assessment followed the following scenarios:
With the above, the following demand projections were obtained for the short, medium and long time considerations using the different growth rates of 7.5, 10 and 11.5 % considered.Table.1 Electricity peak demand projection for Nigeria
Table 2. Projected Access to Grid Electricity by Household for Nigeria(Note that electricity can be from fossil, nuclear or renewable energy source)
The NEP, and indeed the renewable energy component, has amongst other things, five broad objectives:
In 2005, the draft roadmap for the implementation of the renewable component of the NEP, referred to as the Renewable Energy Master Plan (REMP), was produced under the arrowhead of Energy Commission of Nigeria and financially supported by the UNDP. In 2006, a renewable electricity policy was developed for Federal Ministry of Power by ICEED
Energy demand and supply studies conducted by the Energy Commission of Nigeria, taking into consideration the economic vision, demography, available energy resources and modern developmental path, using MAED and MESSAGE energy planning models of IAEA has indicated that huge amount of energy in the form of electricity, fuels and heat would be required to meet this vision.
Use of energy saving devices/energy efficiencyConservation of energy is achieved with the use of energy saving devices. Some of these are as shown here
Listed above are the direct impacts of renewable energy devices deployment on the environment.
In Nigeria however, deployment of Renewable electrification has enhanced the socio-economic situation of the communities electrified, some villages that have been using solar based energy have allowed their communities to feel safe, shop longer and interact with one another during the night.
Energy is very essential for economic growth and development in Nigeria. Nigeria is endowed with sources of renewable energy such as solar, wind, biomass, hydropower, geothermal and ocean waves in addition to fossil fuel sources. The energy from these renewable sources can be transformed to supplement the final energies, from conventional energy, needed to grow the economy in a sustainable manner in the short and medium term; and to serve as substitute, when petroleum becomes uneconomical to exploit. However, adequate policies, programmes, incentives and legal instruments as well as adequate funding are imperative to support and grow the penetration of these new energy sources into the nation’s energy supply mix. It has been shown in this paper that the provision of these clean energy sources will to a good extent allow adequate provision of energy for Institutions and communities that cannot be connected to the grid.
