Renewable energy is proving to be commercially viable for a growing list of consumers and uses. Renewable energy technologies provide many benefits that go well beyond energy alone. More and more, renewable energies are contributing to the three pillars of sustainable development not only in IEA countries, but globally. Turkey is an energy-importing country; more than half of the energy requirement has been supplied by imports. Domestic oil and lignite reserves are limited and lignites are characterized by high ash, sulfur, and moisture content. In this regard, renewable energy resources appear to be one of the most efficient and effective solutions for sustainable energy development in Turkey. Turkey's geographical location has several advantages for the extensive use of most of these renewable energy 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 Turkey. This article presents the role of the renewables in future directions in IEA countries with Turkey. At present the share of hydropower and biomass is high as 30% in the primary energy production of Turkey. In the case of solar, geothermal, and wind energy, there is an important potential for domestic heating and electricity generation.
