Turkey has a large economy and, thus, it expects a very large growth in energy demand. Today, Turkey's economy is mainly dependent on oil, natural gas, and electricity. On the other hand, Turkey's energy production meets nearly 35% of its total primary energy consumption. Turkey is an energy importing country. Turkey presently has considerable renewable energy sources. The most important renewable sources are hydropower, wind, solar, geothermal, and biomass. Turkey has about 1% of the total world hydroelectric potential and its significant potential for geothermal power production is ranked seventh in the world. This paper presents the energy situation and potential of the renewable energy sources in Turkey.
