The condition of Nigeria’s economy in this current dispensation is fast becoming unbearable, prior to the inaccessibility of electricity by 60% to 70% of the masses, and the insufficient circulation of fuel energy. This is a problem at hand! If there must be a buoyant economy, then there must be reliable channels through which energy can be generated from steadily. Our problem in Nigeria as far as energy supply is concerned is that we usually put all our focus and struggles on a particular channel when there are other doors of opportunities that are open wide for us to diversify into. Solar energy, an energy obtained from the sun, is the world’s most abundant and cheapest source of energy available from nature, through which energy can be generated at ease. It is free and renewable. Therefore, as far as this study is concerned, the main point of focus will be on the use of solar system in Nigeria as an alternative source of energy generation considering its importance. The paper will also takes a look into the current problems encountered during the operation process and the use of the solar system, and the preferred solutions with more attention being paid to domestic and industrial utilization.
The length-weight relatonship and condition factor of four mormyrid species namely Mormyrus rume, Hyperopisus bebe, Campylomormyrus tamandua and Gnathonemus petersii from Anambra river were investigated from October 2002 to March 2004. In al400 species M. rume, 384 H. bebe417 C. tamandua and 335 G. petersii were sampled for the study Length-weigh relationship showed that the exponent “b,’ were 3.067, 2.459, 3.201 and 3.114 for M. rume, H. bebe, C. tamandua and G. petersii respectively. The mormyrid species studied with exception of H. bebe exhibited isometric growth and the correlation coefficients were positive and highly sgnificant (P < 0.05). The condtion factor (k) varied from 0.69 ± 0.22 in G. petersii to 1.17 ± 0.59 in M. rume. There were no significant difference in the mean condition facor between themales and females inall the mormyrid species. The importance of condition factor in the breeding activities o the mormyrid species revealed that not much energy s diverted into gonad synthesis and maturation during the breeding cycle season.
"Water is essential for all socio-economic development and for maintaining healthy ecosystems. As population increases and development calls for increased allocations of groundwater and surface water for domestic, agricultural and industrial sectors, the pressure on water resources intensifies, leading to tensions, conflicts among users, and excessive pressure on the environment. The increasing stress on freshwater resources brought about by ever rising demand and profligate use, as well as by growing pollution worldwide, is of serious concern."
Abstract: "The design and construction of a prototype parabolic trough for steam generation was carried out in Nsukka South-East Nigeria. The system was tested for the period of July to October 2014.This was done to explore the possibility of using solar thermal energy produced steam for processing of agricultural produce. The maximum efficiency obtained from the experimental result was 44.51% at ambient temperature of 280C and outlet temperature of 102 ºC. The maximum temperature produced by the system during the testing period was 110°C. The system was fabricated using locally available materials, which accounts for its relatively low performance. A repeat of the study with a stainless steel reflector or with an electro polished aluminium surface as reflector could improve the recorded efficiencies."
"Nigeria has envisioned to grow its economy at a rate of 11% - 13% so that it can be reckoned within the 20 largest economies in the world by 2020. Energy demand and supply studies 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..."
"Energy is a basic necessity for human activity, economic and social development. The productivity and overall performance of sub-Saharan African economies is being hampered by the state of the Energy Sector. Measures to overcome this problem will require the attention of Governments, the international lending agencies, nongovernmental organizations and the various stakeholders. The continent is endowed with RE sources from which modern energy can be produced."
Energy demands for the sustenance of science and technology, locally and internationally, continue to increase as the demands for science and technological goods increase. And everywhere, there is concern over sustainability in energy production, distribution and consumption.
Research shows that poor governance, illiteracy, disease and lack of political will are the major factors hindering development. Our government need act now!
The issue of appropriate pricing of petroleum products and the removal of government’s subsidy on petroleum price became a thorny controversial public policy issue.
The study of aquifer problems in Gosa area of Abuja, North-central Nigeria, has been undertaken. Abuja, the capital city of Nigeria, is underlain by Precambrian basement rocks.
