Abstract- Like the whole world, Turkey’s demand for energy has been growing up annually and is expected to continue to grow. Fossil fuel reserves are limited and these fuels have high level of ash, sulfur and moisture. Accretion of the energy consumption and enviromental pollution have turned out to be a serious problem. Thus, the sustainable energy development of  the renewable energy sources such as solar, wind and solar-hydrogen are accepted as one of the most fruitful and effective solution to prevent enviromental pollution.A model house is designed for this study. Seven cities are selected from among the seven regions of Turkey and need for energy of this model house is provided with wind turbines and photovoltaic systems. Wind potential and hourly radiation data gotten from Turkish State Meteorological Service are used to calculate the energy demand. Cost analysis of these two systems is conducted and energy costs of both systems are compared with the national electrical energy costs.
