“Sectoral Energy Consumption” study had been realized for 2005 reference year according to NACE Rev.1.1 classification for the first time. This study has been revised for 2014 reference year and NACE Rev2 classification. The primary purposes of this study are to determine the final consumption characteristics, to analyze the energy resources in accordance with the type of energy recources consumed and usage areas, to produce sub dissemination data of energy balance sectoral consumption acording to NACE classification, to meet national information demand , to produce statistics harmonised with the related EU regulations and to compile data which constituted resources for various studies.
Classification: For economic activity classification, “NACE Rev. 2” is used for classification of consumed energy resources “PRODTR 2010” is used.
International and regional guidelines: It is suitable for international comparisons in terms of methodology and classification.
Within the determined framework, complete enumeration was implemented to suitable units.
According to the determined sectoral coverage, enterprises with 50 and more employees were covered. Based on energy consumption level of economical activity branches, high level consumption 20 and more employees, low level 100, 250 and more employees, were covered. Energy consumption level was calculated according to results of Annual Industry and Service Statistics and “Sectoral Energy Consumption Survey, 2005” results.
Coverage: All enterprises and their local units in the sectoral context.
Sampling Framework: Address frame in the Business Registers was used.
Total energy consumption: It is energy consumption of energy sources consumed by enterprises in final, transformation process and non-energy use.
Final energy consumption: It is final energy consumption used in production of goods and services, space heating, and transportation by enterprises.
Energy consumption in transformation processes: It is energy consumption used in electricity generation, heat production, coke oven/blast furnace and refineries by enterprises.
Non-energy use: It is energy consumption used for non-energy purposes by enterprises such as raw material use.
Space heating: Use of energy to provide heat in an interior area of a building.
Production of good and services: Using of energy sources directly in the processes for delivery of products to consumers. For example; fuels consumed by vehicles used for mining or heavy construction equipments used for construction, coal used for activities except electricity production in power stations, solid fuel used for melting of iron etc.
Heat production: Hot water or steam production for sale.

Lignite: Coal with high degree of coalification and with a gross calorific value less than 5700 kcal/kg on the ash-free but moist basis. Briquette fuel which re-shaped under high pressure is covered under this category.
Coke oven coke: The solid residue of impure carbon obtained from bituminous coal and other carbonaceous materials after removal of volatile material by destructive distillation. It is used as a fuel and in making steel. Coke scraps are including under this cathegory.
Fuel wood: The pyrolysis of wood and other plant material and covers solid waste consisting of destructive distillation.
Liqueified petroleum gas (LPG): It comprises liquefied propane (C3H8), butane (C4H10) or mixtures of these two hydrocarbons.
Fuel-oil no:4: A complex combination of heavy petroleum hydrocarbons and is a blend of distillate and residual fuel oil. It is used as heating oil.
Fuel-oil no:6: It is a product of petroleum refineries which is produced by distilling crude oil and commonly used in furnaces and boilers.
Gasoline: Light hydrocarbon oil distilling between 35 and 200 °C used in positive ignition engines.
Diesel oil: It is a product of petroleum refineries which is produced by distilling crude oil and it has a high boiling point.
Natural gas: It is a mixture of gas which contains mostly methane and other gases.
Petroleum coke: Shiny-black solid residue, obtained by cracking and carbonization in furnaces and consisting mainly of carbon (90 to 95 %). It is used mainly in metallurgical processes.
Asphaltite: Non-agglomerating coals with a gross calorific value between 17 435 kJ/kg (4 165 kcal/kg) and 23 865 kJ/kg (5 700 kcal/kg) containing more than 31% volatile matter on a dry mineral matter-free basis.
Olive-pomace oil: This is alternative fuel, not include of sulphur which is waste of Olive Oil Plants
Aviation fuel: This is a kind of fuel using at the aviation. Aviation gasoline, Jet fuel (gasoline type) and Jet fuel (kerosene type) are covered under this category. Jet fuel uses for aviation turbine power units.
Kerosene: Includes proceed oil fractions.
Acetylene: Acetylene is a pretty flammable and combustible liqufied gas. Generally used in Oxygen welding machine, lighthouses, chemical industry, some places which needs high flame heat and laboratories.
Propane: This is a straight –chain hydrocarbone, normally in case of gaseous state. Obtained from natural gas and refinery fuel gas.
Liquefied natural gas (LNG):Natural gas cooled to approximately –160°C under atmospheric pressure condenses to its liquid form called LNG. LNG is odourless, colourless, non-corrosive and non-toxic.
Compressed natural gas (CNG):CNG is natural gas for use in special CNG vehicles, where it is stored in high-pressure fuel cylinders. CNG's use stems in part from its clean burning properties, as it produces fewer exhaust and greenhouse gas emissions than motor gasoline or diesel oil. It is used most frequently in light-duty passenger vehicles and pickup trucks, medium-duty delivery trucks, and in transit and school buses.
Biogas (landfill gas etc.): A gas composed principally of methane and carbon dioxide produced by anaerobic digestion of biomass. It is comprising landfill gas, formed by the digestion of landfilled wastes, sewage sludge gas, produced from the anaerobic fermentation of sewage sludge and other biogas, such as biogas produced from the anaerobic fermentation of animal slurries and of wastes in abattoirs, breweries and other agro-food industries
Blast furnace gas: Obtained as a by-product in operating blast furnaces; it is recovered on leaving the furnaces and used partly within the plant and partly in other steel industry processes or in power stations equipped to burn it. The quantity of fuel should be reported on a gross calorific value.
Coke Oven Gas: Obtained as a by-product of solid fuel carbonisation and gasification operations carried out by coke producers and iron and steel plants which are not connected with gas Works and municipal gas plants. The quantity of fuel should be reported on a gross calorific value.
Steel-furnace gas: Obtained as a by-product of the production of steel in an oxygen furnace; it is recovered on leaving the furnace. The gas is also knownn as converter gas, BOS (basic oxygen steel) or LD gas. The quantity of fuel should be reported on a gross calorific value.
Steam-hot water: It refers to vaporized water. Steam is pure at around 100 degrees Celsius temperatures and standard atmospheric pressure. Gas is transparent and volume is more over 1600 times to water. Steam is inherently hotter than the boiling point of water.
Geothermal: Energy available as heat emitted from within the earth's crust, usually in the form of hot water or steam. It is exploited at suitable sites: For electricity generation using dry steam or high enthalpy brine after flashing. Directly as heat for district heating, agriculture, etc.
Wood: Covers purpose-grown energy crops (poplar, willow, etc.), a multitude of woody materials generated by an industrial process (wood/paper industry in particular) provided directly by forestry and agriculture (firewood, wood chips, bark, sawdust, shavings, chips, black liquor, etc.)
Shell: Provided directly by forestry and agriculture and they are woody materials comprising the shell of the products like hazelnuts, walnuts.
Wood shavings: Wood residues supplied directly from agricultural and forestry. Residues are the woody material formed by the grating.
Other: Energy sources which consumed in low quantities relatively by enterprises like refinery gas, black liquor, tar and gel fuel aggregated under this cathegory.
The calorific value (or energy value or heating value): The amount of heat released during the combustion of a specified amount of it. The energy value is a characteristic for each substance. It is measured in units of energy per unit of the substance, usually mass, such as: kJ/kg, kJ/mol, kcal/kg, Btu/lb.
