This paper discussed the efficient system of sustainable renewable energy for domestic used and its total cost. The method of this paper was the collection of the basic data of solar radiation, wind speed and other required input data, and then hybrid optimization simulation model was developed using the electric renewable energy software hybrid optimization model of renewable energy (HOMER). Simulation model has been used to find out the best technically viable renewable based energy efficient system for different numbers of household. The result of some topologies of hybrid power was found. Simulation results have been presented as the most efficient achievement and economic way for different numbers of household. The overall cost of energy would be low if the turbine cost decreases in Khartoum. The project life time has been considered for 25 years and the annual real interest rate has been taken as 4%. The coast in 25 homes was found to be 1,567,220 USA $.
