Since power generation is one of the key factor in developing the country's economy in Nigeria, the need to look at the way of reducing the negative impacts of these power plants are also required so as not to hinder the life of inhabitants of the country. In this paper, emphasis is majorly placed on thermal power plants, since it's the main generating method that is employed by Nigeria because the county is blessed with its materials such as natural gas and coal. But looking at this generating means, it has a lot of environmental impacts which can cause harms to the life of people in the country together with aquatic lives. These harmful effects include the release of greenhouse gases, water pollutions and so on. Therefore, to reduce the harmful effects and improving the operation of these power stations, this paper suggested some modern technologies which can be employed by the power stations to reduce the harmful effects being caused by the power plants such as CO 2 emission, NO x emission, particulate matter, SO x and so on. Also, it tells us the ways by which electricity is generated from Short Research Articlethe raw materials being used, their environmental impacts, ways of reducing these impacts and some of the difficulties encountered by thermal power stations in Nigeria.

Power generation is the means of generating power supply into the society. This paper tells how power is being generated from various sources (nuclear, coal, solar, wind, natural gas, water, geothermal, biomass), its major impacts on the society and the possible solution to problems that arise from the process of power generation through the various means considered. The various methods of generating power, no matter how beneficial, still have one or two short-comings which might constitute threat to the peaceful coexistence of living things in the environment. Some of these shortcomings are considered in this paper with possible solutions suggested. Over-aged transmission and distribution lines, unequal phase loads, etc. contribute to electrical power losses in transmission and distribution in Nigeria.To solve these problems, control measures such as introducing more substations, implementing pre-paid metering systems, using conductors of appropriate sizes and re-aligning the lines are suggested. In order to ensure sustainable power generation, foreign participation based on experience should be encouraged in the Nigerian power sector, the sources of fuel for electricity generating stations should be diversified, etc.

The rapid expansion of the use of internet in the last decade has been made feasible largely by optical networks with high bandwidth and consistency. This paper explores the meaning of grooming, the methodological context in which it can be applied. An innovative nomenclature incarcerates useful aspects of grooming problems and is used to review publications on traffic-engineering and optimization problem class. The paper proposed an efficient traffic grooming model for all optical networks. The model has low complexity and it can be easily implemented for traffic grooming problems.
