According to the Solar Energy Map (SEM) of Turkey prepared by the Renewable Energy General Directorate, it has been determined that the total annual insolation time is 2.741 hours (a total of 7,5 hours per day), and the total solar energy derived per year is 1.527 kWh/m² per year (total 4,18 kWh/m² per day). While solar energy technologies are extremely varied in terms of their methods, materials and technological levels, they can be split into two principal groups:

Photo-emissive Solar Technologies and Concentrated Solar Power (CSP):In this system heat is obtained from solar energy, and can be used either directly or in the generation of electricity.

Solar Cells:Semi-conducting materials, which are also known as photovoltaic solar energy systems, convert the sunlight directly into electricity.

The total established solar collector area within our country as of 2017 was calculated as being close to 20.000.000 m². Also, in 2017, close to 823.000 TEP Tonnes Equivalent to Petrol) heat energy was produced using solar collectors.

As of the end of 2017, there were 3.616 solar power plants with a total installed capacity of 3.421 MW. This is the equivalent of 4% of the total potential. In 2017, electricity production based on solar energy have realized 2.684 GWh and 0,91% of our electricity production was obtained from solar energy.

The characteristics of the wind differs (in respect of time and region), based on local geographic differences and the non-homogenous temperatures of the surface of the earth. Wind is stated as two separate parameters – speed and direction. The speed of the wind rises with height, and its theoretical strength changes proportionately to its cubic speed. The initial investment costs of wind energy applications are high, and their capacity factors are low. Together with this, they have the disadvantage of inconsistent energy production. Their advantages, on the other hand, can be listed as follows:

Wind turbines can be manufactured either with a horizontal or a vertical axis, based on the direction of their rotational axis. Wind turbines with a horizontal axis are more widely used.

Wind turbines are only able to start generating electricity energy at a specific wind speed. A wind turbine will generate energy in between the cut-in and cut-out speeds. The cut-in speeds of modern wind turbines are between 2-4 m/s, their nominal speeds are between 10-15 m/s, and their cut out speeds are between 25-35 m/s. Each wind turbine reaches the maximum power value which can be obtained from the system at a specific wind speed. This maximum power is known as nominal power and the wind speed at this level is known as the nominal speed. Wind turbines automatically stop after a certain wind speed has been exceeded, in order to ensure that the system is not damaged. This maximum speed is known as the system cut-out speed.

The body possesses sound insulation in order to prevent noise pollution. The towers are built in the form of cages or pipes. As the towers can be very high, the constructions outside the cage towers can consist of two or three parts.

It has been accepted that wind plants with a capacity of 5 MW can be established in Turkey at heights of 50 meters above ground level, and in areas with a wind speed exceeding 7.5 m/s. In the light of this acceptance, a Potential Wind Energy Map (PWEM) has been prepared, where the source wind details obtained using a mid-scale weather forecast model and micro-scale wind flow model are given. The wind energy potential of Turkey has been estimated as 48.000 MW. The total area which is equivalent to this potential is just 1.30% of the total surface area of Turkey.

Hydroelectricity plants work in harmony with the environment, are clean, renewable, and highly productive plants with no fuel expenses. They take on the role of an insurance in energy prices, have a long lifespan, low operating costs, and are not dependent on imports.

Our hydraulic resources, which hold the most important position in the renewable energy potential of our country, possess a hydroelectricity potential of 433 billion kWh, while the technically usable potential is 216 kWh, and the economic hydroelectricity potential is 140 billion kWh/year.

As of the end of 2017, there were 628 hydropower plants, with a total installed capacity of 27.273 MW. This is the equivalent of 32% of the total potential. In 2017, hydroelectricity production have realized 58,5 billion kWh and 19,8% of our electricity production was obtained from hydropower.

Turkey is located on an active tectonic zone as geological and geographical location, and for this reason our country is rich in terms of geothermal energy resources. Our country have approximately 1.000 geothermal springs that located all over the country that have various of temperatures.

In theory, the geothermal capacity of our country is predicted as 31.500 MWt. 78% of these geothermal fields are situated in Western Anatolia, 9 in Central Anatolia, 7% in the Marmara Region, 5% in Eastern Anatolia and 1% in the other regions. 90% of our geothermal resources are low and medium enthalphied Geothermal areas which are suitable for direct applications (heating, thermal tourism, the output of minerals, etc.), while 10% are suitable for indirect applications (generation of electricity).

In 2005, with the support of our ministry, the development of existing geothermal resources initiated and began to search for new potential areas. Due for this mobilization, our usable geothermal heat capacity increased with total 223.000 meter drillings and additional 1.900 MWt heat energy increase was provided. Also, discovered geothermal fields reached to 234 fields. As a result of total of 613 drillings with total of 383.000 meters of depth carried out to this day, 5.000 MWt of heat energy was obtained including natural outflows.

Our electricity infrastructure strengthened in our country and the production increase in parallel with the increase in consumption was recorded. In addition, The connection of our electricity system with the European electricity system has also been strengthened. Long Term Agreement was signed between TEIAS and ENTSO-E on April 15, 2015. By this way, our country's electricity system has been permanently connected to the European electricity system. TEIAS also became the first and only observer member of ENTSO-E with the observer membership agreement on 14 January 2016.

In line with the aim of liberalising the electricity market, it has been set forth that new generation investments be carried out by the private sector, in accordance with the new Electricity Market Legislation numbered 6446.

It is aimed that a transparent and competitive market be formed in the electricity sector, and that the environment for investment be developed in this way. Within this scope, EPIAS (Electricity Markets Operating Corporation) has been established and started its operations.
