“…The CP content of WB was 172.9 g/kg DM, which was higher than the values (160, 165 and 168.2 g/kg DM) obtained by Feyera andAnimut, (2011), Solomon (2004) and Hagos and Melaku (2009), respectively, but lower than the value (199.9 g/kg DM) reported by Alemu (1981). This diff erence in CP values obtained by diff erent scholars might be due to the soil type where the wheat had grown, storage and processing techniques in the milling industry (McDonand, 2002).…”

The Objective of this study was to evaluate the eff ect of supplementation with Moringa stenopetala leaf meal (MSLM) 03 + 0.41, 17.25 + 0.33, 17.5 + 0.60, 17.7 + 0. 19 and 18.01 + 0.24 T2, T3, T4 and T5 gained 71.1, 51.5, 46.7 and 44.4 g/ head/day, respectively kg, respectively. The treatment feeds were adlibitum feeding of Rhodes grass hay alone (T1) or with daily supplementation of 300g dry matter (DM) sole MSLM (T2), 2MSLM:1WB mix (T3), 1MSLM:2WB mix (T4) and sole WB (T5). The data on nutrient content, feed intake, body weight gain, and digestibility were analyzed using Proc Mixed procedure SAS (SAS Institute, USA, version 9.4). The model included treatment as fi xed factor, while experimental animals were included as a random factor. The crude protein content, total dry matter intake (DMI) and

“…HOMER simulation software was developed by the United States National Renewable Energy Laboratory (NREL) used to simulate and suggest a feasible system for all possible combination of a component by making energy balance calculations in time steps of yearly data [9]. In each interval or time step, HOMER compares the electric and thermal demand in that time step to the energy that the system can supply and calculates the flow of energy to and from each component of the system [10]. This analysis uses the latest version of HOMER, namely Homer Pro, which features a new optimization algorithm to examine the least-cost system for rural application.…”

Photovoltaic hybrid power generation is an alternative solution for supplying electricity to rural areas, especially in Sarawak, Malaysia, where grid connection is almost impossible due to the cost and geographic location. Diesel generator systems are still used by local communities in these remote areas, and the implementation of photovoltaic diesel hybrid systems can reduce dependency on diesel generator units. The work presented in this paper explores the possibility of integrating solar energy resource with diesel generator to meet the load demand of rural communities in Sarawak. In further detail, the configuration and size of the PV-diesel system are analyzed in based on the lowest net present cost (NPC) and the cost of electricity (COE). The analysis is based on mathematical modeling and simulation using Hybrid Optimization Model for Electric Renewables (HOMER) software. Eight different configurations of two energy resources-photovoltaic panels and diesel generators-are studied and compared. The option with the highest optimization values is considered to be the most feasible electrification solution for the particular rural area. The outcomes of the analysis show that the PV-diesel hybrid configuration proves to be more cost-effective compared to an existing generator-based system in that it reduces fuel dependency and has the lowest NPC and COE among all configurations studied.

“…Most important alternative investments conserve energy, improve environmental sustainability, improve energy equity and improve the country's development indicators as shown in table 1. The Ethiopian energy report predictable energy request in different sector from 2015 to 2037 by the Ethiopian Economic Plan [13,14]. As different area energy needs as Agriculture Sector (197 to 5219MW) it increases 25.67% increase, Industrial Sector (447 to 7002MW) it increases 16.07%, service sector (304 to 2624) it increases 8.7% and transport sector (97 to 1564MW) it increases 16.4% in energy per time and power [15].…”

The objective of the study is to provide scientific information of the solar potential of Afar region, for photovoltaic (PV) solar energy industry sectors. The afar region being exceptional solar potential with high average solar radiation flux 239.9W/m 2 (105.4% of average photon energy surface area of Ethiopia), and average annual solar density of 2.102MW•h/m 2 (105.5% of the average yearly solar density of Ethiopia). This finding requests the photovoltaic system as an alternative principal energy resource to substitute the present energy system in afar region. These comprehensive indication of the solar energy marketplace in Afar region, Ethiopia, key visions into its governing framework, energy sector, of photovoltaic (PV) industry segments. Therefore, the photovoltaic energy system has the best opportunity for basic energy application in the pastoral community for daily life consumption, such as solar lighting, for solar cooker, small devices and for air conditioning. These studies show that the Afar region gifted with significantly high monthly average daily solar radiation as a potential candidate for development of PV energy systems in Afar region. Therefore, the PV system has the power to run an evaporative air conditioning system effectively. These findings indicate that photovoltaic energy system as most promising energy in the Afar region.
