In the first part of
the above titled article, we established that for any African country to be
self-sufficient and industrialized, it is necessary to have a sound energy
policy and embark on a diversified energy strategy. A diversified energy
is necessary to improve the quality of lives of citizens. The
diversification may include, among other possibilities, Biomass, energy from
fossil, hydroelectric, micro-hydroelectric, Solar, Ocean waves and wind and
last but not the least, Nuclear. The option of nuclear energy must be
carefully considered especially fro a developing world because the by-products
are difficult to dispose of (ask US and Russia). A country that embarks
on a diversified energy will improve its quality of life through good
healthcare delivery, improve its industrial base, enjoy increased foreign
investments, indirectly discourage brain drain and hence enjoy advance
technology transfer. To this end, there need to be a paradigm shift in
governmental energy policies toward industrialization in the 21st
century, a re-thinking of her energy and industrial strategies that can lead to
stellar capacity utilization.
The idea of seeking
helping hands from government other than sound energy policies must be
discouraged, not from inefficient government and political leaders that see
politics as a way for self aggrandizement. In Nigeria, for example, every
achievable business success is tied to who one knows in government. For
Nigerian energy professionals to divorce their success from a tie to
government, they must work with anti-corruption agencies to rid the nation of
corruption and begin to challenge those enemies of Nigeria that tag more that
140 million citizens as corrupt for the sins of a few citizens. It is
only through these efforts that the professionals can discuss with those
trusted investors colleagues in Diaspora and in Nigeria that Nigerian energy
sector is the next frontier to conquer and were gazillion Naira or dollars will
be made on a FIFO basis.
Although citizens
should not expect too much helping hands from their government, currently,
successes in every the industrial sectors in Nigeria depend partly or wholly on
Federal and state government inputs. The only demand by energy
professionals from any reliable, and people-focused government (Federal and
States), should be sound energy policies. Once good energy policies are
established, public and private sectors will have confidence in attracting both
national and foreign investors who will be willing to pump investment funds
into the energy sectors just like in the communication sector. But first,
government policies must address: a) Institutions finance and markets; b) the
endemic corruptions that has stifled the nations growth and infrastructural
developments; c) The nations capacity utilization; c) Energy sectors
management and efficiency; d) Local and Regional Environmental Impact of Energy;
and e) Climate Change impact. Most individuals and corporations in
Nigeria currently depend on noisy and environmentally degrading generators to
produce services and products and this must stop.
Stable energy sector will bring about
industrial development. Industrial development always follows the
progressive establishment of primary, and secondary and tertiary
industries. Primary industries process can add values to agricultural or
natural resources, while secondary industries utilize the products of primary
industries with or without natural resources. Tertiary industries are of later
developments and they depend on the output of secondary industries among other
inputs. At the onset, primary industries are mainly on small scales
because of limited infrastructure, capital, technical expertise and managerial
skills. At this point in time, the growth of small-scale primary
industries holds the key to industrial development in Nigeria.
On the other hand,
appropriate small-scale industries will add value to local resources; promote
the development of artisans, technicians, engineers and managers. These
industries will provide employment; foster economic growth and could sustain
the economy when the Nigerian oil sector is depressed. The choice of
small-scale industries will depend on local resources that could be
commercialized.
THE DISTURBING
ATTITUDES OF NIGERIAN PROFESSIONALS
Nigerian
professionals have never understood what cooperation contributes to the bottom
line, take off of businesses, research implementation, and for the development
of a nation. If anyone has ever interacted with most Nigerian
professionals, they seem to have ideas but when it comes to implementation,
there are more chiefs than Indians. All want to be the CEO of a
corporation that is generating zero revenue. In my own view, I believe
there must be a change of attitude of those willing to work for the success of
a system and allowing identified goal getters to stir the ship for greater
financial and national success. In the oil and gas sector, for example,
there are so many small companies providing menial services in the upstream and
downstream sectors instead of two or three smart and energetic Nigerians
joining together, hiring an independent but active CEO to move the company
forward, they settle for being MD in a Mom and Pap store type of business. What
I am leading to in this article is that Nigerian professionals need to trust
themselves write an enforceable by-laws, and run credible, globally recognized
corporation. The energy sector should take a lead in this venture.
SOLAR/PHOTOVOLTAIC
ENERGY GENERATION, ADVANTAGES AND DISADVANTAGES
Some African
countries are exploring solar or Photovoltaic (PV) energy to augment the energy
generated from fossil fuel or to use solar energy as a stand-alone in rural and
even urban residential and industrial complexes. Energy professionals who
will be guided by sound energy policies from Federal and State governments must
help Nigeria in: a) establishing realizable standards; b) Becoming a beckon of
hope in erasing dark days; c) Frustrating the generator and diesel cabals
efforts in stopping the wheel of progress in the nation for selfish reasons; d)
Encourage hard work and industry; and e) become a true gateway to
industrialization.
In Kwara state
which is my state, as in most neighboring States, agriculture is the main stay
and it should be focused on during the initial industrial development.
Developing this sector aligns well with existing social structure and needs,
and paves way for a smooth transition to long-term industrialization.
When it is all said and done, sustainable energy of which solar energy is a
part, is still the key to industrialization in developing countries.
ADVANTAGES AND
DISADVANTAGES OF SOLAR ENERGY
There are obvious advantages and
disadvantages of solar energy. The advantages of solar or Photovoltaic
(PV) are
a) ECONOMIC
IMPACT
· Solar energy provides superior lighting at
the least cost when compared to utility power or generators. Monthly
payments for solar home system are often below what a family would pay for
kerosene, dry-cell batteries and candles.
· Solar electric systems can extend the
productive work-day. It is dark by 6:00 PM year round in equatorial
latitudes and electric lighting only allows families extend their work-day to
evening hours.
· Solar energy helps to foster
micro-enterprise development. Enterprises in local towns and small shops
can benefit by using the system to provide light during power outages and
especially when utility power is not available. For example, small
businesses utilizing electric sewing machines, water pumps, and computers to
provide services to the locals can benefit from solar electric system.
For these types of businesses, there would be no need for storage system
because the businesses are operated during high sun hours.
· Solar can create direct and indirect
employment opportunities in the Nigerian States. For instance, local
businesses that sell and service solar home systems can spring up thus
providing employments for local residents. Dealers, regulated technicians
via standardization can be employed selling and servicing solar home systems.
· Solar energy system can facilitate the
development of micro-lending programs. Revolving credit funds and other
financing mechanism may be utilized for the purpose of purchasing solar home
systems. Such credit servicing can become a vehicle for local financial
institutions to set aside small funds such as loans to rural businesses for
quick turn around.
· Solar also helps to conserve foreign
exchange. As much as 90% of the export earnings of some developed
countries are used to pay for imported oil and spare parts, mostly for
generators. Capitals saved by not building large power plants can be used
for investing in health, education, economic development, and industry.
Expanding solar rural electrification creates jobs and business opportunities
based on an appropriate technology in decentralized marketplace.
b) EDUCATIONAL IMPACT
· Solar
electrification improves literacy by providing high quality electric reading
lights. Electric lighting is far brighter than kerosene or candle
lightening and it can prevent house burning.
· Solar
increases access to news and educational programming through television and
radio broadcasts. With the advent of television and radio people who were
previously cut off from electronic information, educational and entertainment
can be reconnected at minimal cost.
· On
going education classes and adult literacy can be encouraged and held during
the evening hours in solar-lit community centers when other days work is
completed.
· Solar
lightening can provides residential lights so that men of the underworld who
need darkness to work will be discouraged fro operating and might even be
encouraged to take on genuine works that are legal and assuring;
· Solar
electricity, when coupled with wireless communications can encourage rural
phone and data communication services to remote villages. It can also
help in reporting of accidents to area emergency medical centers thus saving
valuable lives; and more importantly,
· Imagine
how beautiful an environment, and proud our students would be when placed in an
environment well lit, air-conditioned primary, secondary, and other tertiary
schools with modern telecommunication technologies. A healthy educational
environment provides a healthy mind and a sound research vision.
c) HEALTH IMPACT
· Kerosene
lamps are serious fire hazard in developing world killing and maiming tens of
thousands of economic productive citizens each year. Kerosene, diesel
fuel and gasoline when stored for use in powering lamps and small generators
are often safety hazards, whereas, solar electric lamps are entirely safe.
· Solar
improves indoor air quality and environment. Fume from kerosene lamps in
poorly ventilated homes are serious health problem in much of the world where
electric light is erratic or unavailable. The World Bank estimates that
780 million women and children breathing kerosene fumes inhale the equivalent
of smoke from two packs of cigarette a day.
· The
use of solar electric lighting systems by rural health centers increases the
quality of healthcare provided. Solar electric systems improve patient
diagnoses through task lighting and use of electrically lit microscopes.
Photovoltaic system can power televisions and VCRs in order to educate
healthcare workers and patients about preventive care, medical procedures, and
other healthcare provisions.
· Finally,
solar electric refrigerators have a higher degree of temperature control than
kerosene units and this leads to lower vaccine spoilage rates and increased
immunization effectiveness.
d) ENVIRONMENTAL
IMPACT
· With decrease in the amount of kerosene use
for lighting there is corresponding reduction in the amount of local pollution
produced. Solar rural electrification also decreases the amount of electricity
needed from small diesel generators;
· Solar offsets greenhouse gases.
Photovoltaic systems produce electric power with no carbon dioxide (CO2)
emissions. Carbon emission offset is calculated at approximately 6 tons
of CO2 over the twenty-year life of one PV system;
· For developing world, solar is an effective
energy conservation program because it allows costly conventional power for
urban, town market centers, and industrial and commercial uses and leaves
decentralized PV generated power to provide lighting and basic electrical
needs of the majority of rural populations; and
· The small cell batteries used for
flashlights and radios provide source of energy for un-electrified world.
Most of these batteries are disposable lead-acid cells which are not
recycled. Lead from disposed dry-cells is absorbed into the ground
thereby contaminating soil water. Solar rural electrification decreases
the lead absorbed due to less battery use since over fourteen million batteries
were sold in 2003.
ADVANTAGES OF SOLAR POWER OVER GENERATORS
· Solar is passive and eliminates the noise
that results from generators;
· Solar power contains no moving parts and
hence there is little or no maintenance required;
· Solar is modular which implies that one can
start with a small system and later add to it as ones needs increase. A
generator, on the other hands, will not allow this flexibility;
· Unlike generators, solar systems do not
create pollution;
· Solar eliminates the need for diesel and/or
petrol which are often in short supply and renders both residential and
industrial complexes useless for days and even weeks;
· Unlike a generator, solar only needs battery
bank to store excess energy which can be used at a later time and date;
· To run a generator, the same amount of
diesel/petrol is required even if one is powering a 10-Watt bulb; and
· Solar panels are warranted for a minimum of
25 years.
One disadvantage
that many refer to is the fact that solar technology is still in its
infancy. This is partly true but many scientists are working to correct
the shortcomings in solar system. In fact, many nations are designing
homes that are solely solar powered. Even, the disadvantage of any system
provides future research and improvement for capable scientists. Rather
than always focusing on the negative and why an idea will not work, it may be
equally important to discuss how the system can improve.
For a start,
communities can begin to integration of solar systems by powering streetlights
in their subdivisions. If this works, many may decide to employ solar
energy to power their lamps, fans, outdoor lights, and for solar power
pumping. Any short fall in the solar system output can be corrected by
professionals. This is how we can integrate solar energy into the never
working NEPA and force NEPA to be efficient.
Finally on the
solar system, the energy Wattage derived will be a
product of required use and the capacity of the storage. This will be
discussed if specific design needs are presented. Moreover, the strategy
in this write up is to provide general ideas for the renewable energies before
discussing the feasibility studies and economic impact necessary to give
investors ideas of the opportunities inherent in any chosen renewable energy
system. The knowledge presented here will also give an investor idea on
how he can achieve a good return on his investment. The studies needed may be
funded by interested parties and even sometimes governmental agencies as in the
case of the Internet which private companies are enjoying today.
