Clean, domestic and renewable energy is commonly accepted as the key for future life, not only for Turkey but also for the world. All nations, regardless of their degree of development, are trying to develop and apply technologies that will enable them to use renewable energy sources in the most efficient ways. Turkey＇s geographical location has several advantages for extensive use of most of these sources. Because of this and the fact that it has limited fossil fuel resources, a gradual shift from fossil fuels to renewables seems to be serious and the sole alternative for the country. Turkey＇s renewable energy source potential and their present use are here evaluated based on the available data.
