Abstract: The unceasing and phenomenal rise in oil prices and drastic need to reduce gas emissions causing to craft policies to boost the energy generation through the renewable energies. The non-conventional energy sources like wind power, mini-hydro, solar, etc having a significant contribution in energy production. The empathy and effective use of renewable energy resources are the plunge areas in the development of energy sector. Among all these wind energy is one of the utmost atmosphere pleasant, clean and benign energy assets. The wind energy will remain to be the chief in renewable energy sector in any country. The assimilation of wind energy into current power system boons technical challenges of power quality measurements such as variation of voltage, reactive power, flicker, harmonics, and electrical behavior of switching operation. So to have consistent renewable energy it is necessary to reduce these problems associated with the addition of renewable energy into the power grid. So the major purpose of this paper is to study the practical encounters that affect quality of power included: voltage flicker, Impact of nonlinear load on harmonics generation, reactive power, switching operation in the power system and the damages caused by these issues.

Abstract: Growing concern regarding energy resources and the environment has increased interest in the study of alternative sources of energy. To meet increasing energy requirements, there has been growing interest in alternative fuels like biodiesel to provide a suitable diesel oil substitute for internal combustion engines. Biodiesels offer a very promising alternative to diesel oil since they are renewable and have similar properties. It is a promising substitute as an alternative fuel and has gained significant attention due to the predicted shortness of conventional fuels and environmental concern. The utilization of liquid fuels such as biodiesel produced from waste cooking oil by transesterification process represents one of the most promising options for the use of conventional fossil fuels. However, as the biodiesel is produced from vegetable oils and animal fats, there are concerns that biodiesel feedstock may compete with food supply in the long-term. Hence, the recent focus rely on using waste cooking oil as the substantial feed stocks for biodiesel production.

Abstract: The diesel driven water pumping systems have a great impact on irrigation in remote areas around the world. However the gradual increase of fuel prices worldwide and high maintenance cost discourages the utilization of the technology. Therefore, it is important to think of an alternative energy source for such application. The optimal sizing of this PV water pumping provides theoretical studies of photovoltaics and modelling of electric power requirement for powering pump to irrigate crops as an alternative to diesel technology. The analysis employs determining the optimum tilt angle of solar panel which can collect the maximum solar energy when irrigation water demand could be higher based on seasonal Variation. The irrigation requirement has been determined by combining climate inputs, hydrology, crop type and developing stage, soil type, moisture and irrigation method etc. at each time stage of irrigation period. The power requirement has been analysed using dynamic programming by relating hydraulic load with the solar radiation energy from the solar panel for each decadal irrigation period. The maximum power has been minimized so as to select the power which can satisfy all irrigation periods with reduced cost of PV system. Furthermore Pumps (Centrifugal surfaces) with high discharge and low heads are selected to minimize water cost for such application as surface water sources from rivers and ponds are mostly applicable for irrigation in Ethiopia.

Abstract: Assessment of Global Solar Radiation Absorbed in Maiduguri, Nigeria was carried out in order to assist researchers in the field of solar radiation especially in developing countries that are increasingly faced with a serious data constraint. This will prove useful to many fields of study that rely on atmospheric energy input. The irradiation data was measured with the aid of constructed solar cell-based Pyranometer called the Reliable Model Pyranometer (RMP 002) at promising site. Insolation data at 1 min intervals were recorded for Maiduguri, Nigeria, using data loggers. The data were stored in a propriety binary format and later saved as text files that were imported into excel. From the data obtained, it was observed that maximum values of insolation occurred during the winter period while the minimum occurred during the summer period.
