This document outlines a presentation about accelerating the development of renewable energy irrigation systems in Nigeria. It discusses Nigeria's potential for solar and wind energy given the climate. A hybrid solar-wind power technology is proposed for powering irrigation pumps on farms. The current state of renewable energy and irrigation projects in Nigeria is described, along with constraints and proposed strategies to increase renewable energy development. The impacts would include increased income, quality of life, and job efficiency for farmers. The conclusion is that Nigeria has good solar and wind resources that could be leveraged to power irrigation and support agriculture, which is currently highly dependent on rainfall.

3. INTRODUCTION
Renewable energy (RE) are those sources whose development into
useful energy are inexhaustible.
Renewable energy – clean, reliable, and indigenous – they are well-positioned
to fill Nigeria’s growing needs for generating capacity.
(RE) as an alternative energy is fast becoming viable and in some
circumstances, they are said to be approaching “ grid parity” with fuel
powered plant for electric power supply .
The (RE) sources available to us include:
• Small hydro power
• Solar ( PV /Thermal)
• Wind (Turbine/Windmill)
• Tidal
• Biomass
• Hydrogen-powered fuel cells
• Geothermal.
 For the purpose of this presentation, the (RE) sources that will be
considered for power supply to irrigation systems are: Solar PV and
Wind Turbine (I.e. Hybrid solar –wind system)

Several factors ( i.e. key Drivers) that explain why RE (Renewable Energy )
are the world fastest growing energy resources are ;

Can the use of hybrid solar –wind system for irrigation farming
make a difference ?

5. RE RESOURCE POTENTIAL IN NIG. -
SOLAR ENERGY
Solar energy is the most promising of the renewable energy sources in view
of its apparent limitless potential. The sun radiates its energy at the rate of
about 3.8 x 10E23 (KW) per second.

6. SOLAR ENERGY – CONT’D

With an average annual sunshine of 1500 hours per year, Nigeria enjoys
excellent solar exposure throughout the country .
Nigeria isolation value ranges from an average of 3.5kWh/m2/day in the
coastal states to
7 kWh/m2/day in the northern states .
This means that solar energy is a viable option for meeting the energy
demand of an average Nigerian farmer.

7. RE RESOURCE POTENTIAL IN NIG.-
WIND ENERGY
7
Wind is a natural phenomenon related to the movement of air masses
caused primarily by the differential solar heating of the earth’s surface.

8. Wind energy resources cont’d
A study on the Wind energy potential for a number of Nigeria cities shows
that the annual average wind speed at 10m heights varies from about
2m/s in the Coastal areas to about 4m/s in the far north(
RUGBERE,D.K.(2006)).

In contrast to a windmill , a
modern wind turbine power
generator is designed to
produce high quality,
network frequency electricity
whenever enough wind is
available.

11. In Nigeria, the current status of Irrigation is a far cry from what it ought to be.
The north part with its lower rainfall and shorter rainy season consists of
savanna land and this represents 80% of the vegetation zone of the country

IRRIGATION IN NIGERIA
According to NINCID (2009), recent survey suggest that 39% of the land mass is
potentially suitable for agriculture and out of this between 4.0 and 4.5 million ha
(approximately 4.5 to 5.0%of the land) are judged suitable for irrigated agriculture but
only 1.1 million ha can be supported fully by the water available, the remaining 3.4
million ha being Fadama.

12. CONSTRAINTS
There are a number of economic, technical, social and institutional constraints that
have been EXPERIENCED, OBSERVED & RECORDED to be withholding the
widespread development of Renewable energy technologies for irrigation water
pumping purposes. Although most of the issues have since been receiving
attention. They include :
12
 High initial investment costs
 Lack of clear, inconsistent National policies and priority
 Longer construction period due to resource assessment and validation
 Lack off adequate awareness on Renewable Energy Technologies
 Lack of access to affordable finance
 Dependence on nature
 High Cost of Operations and Maintenance [O&M]
 Inadequate availability of local expertise

13. STRATEGIES
The following strategies and steps are likely to intensify
the pace of development of renewable energy projects for
irrigation system. To achieve this, a concerted effort by the
Government, NGOs, private investors, professional
societies, financial institutions and progressive individuals
are urgently needed.
Suggested strategies includes:
13
 Demonstration, Training & Implementation
 Institutional Policy, Information awareness & Planning
 Research & Development (R&D)
 Flexible financing & innovative business concepts
 Undertake an analysis of (strengths, weaknesses,
opportunities and threats [SWOT]) to help reveal any
potential conflict that could arise from renewable energy
promotion and identify fields of action.

14. LIKELY IMPACTS
Linking Renewable energy with productive uses such as irrigation system
will
 Create opportunities (farmers are less likely to move away to urban areas
in search of employment)
 Raise income level (Farmers will sell surplus produce at local /interstate
markets)
 Improve quality of life of the farmers in rural areas (environmental point
of view)
 It will increase job efficiency as working hours under the new
system(drip irrigation) will be halved.
The progress of matching RET & IRRIGATION can be monitored in relation to
social, technical, economical and environmental factors .This could
influence the project’s success and opportunities for replication in the
places.

15. CONCLUSION
From all indication, it is clear that Nigeria has great solar and
fairly good wind energy potentials, but our development
toward these inexhaustible power sources for various
applications are very low and almost non existent for
irrigation farming.
 The agriculture in our country is highly dependent on rainfall
 The proposed system is based on renewable energy(solar &
wind ) which is always available without any limitations.
 Technological improvement in system and a new designed
wind turbine & BOS components makes system more
efficient
 The microcontroller makes system automatic and saves man
power and as well as power & wastage of water.
 Adopting solar & wind power for water pumping has
resulted in huge benefits.
The very fact that sources of renewable energy are the future of tomorrow
15
calls in for corporate investment in this field by all of us .
