Production, imports, exports and consumption of renewable energy resources
Data on production, imports, exports and consumption of renewable energy resources, charcoal and waste are used to estimate production and consumption of various renewable energy resources in all sectors of national economy (by main kind of economic activity).
Terms and definitions
Kind of economic activity [energy]
Sphere of activity of the enterprise or individual that expresses itself in the produced goods or services.
The type is determined by Standard Classification of Economic Activities (NACE Rev. 1.1, starting from 2008 – NACE Rev. 2).
In 2008 the data were published according to both NACE Rev. 1.1 and NACE Rev. 2.
Renewable energy resources
Renewable energy resources include wind energy, solar energy, hydro energy, tidal energy, geothermal energy, biomass (wood, straw, biogas, biofuels) and renewable waste.
Waste [energy resources]
Waste includes municipal waste for heating and used rubber tyres.
Production [renewable energy]
Quantity of firewood, wood waste, wood chips, wood briquettes, pelleted wood, bioethanol, biodiesel, biogas, straw and other solid waste produced.
Quantity of energy resources transported across the state border to the third countries and to the EU Member states (without commodity flows to customs warehouses and free economic zones), not including transit.
Quantity of energy resources transported across the state border from the third countries and from the European Union (EU) Member States (without commodity flows from customs warehouses and free economic zones), not including transit.
Total consumption [energy]
Consumption of energy resources by transformation sector, energy sector, all sectors of national economy, as well as by households.
Gross consumption of charcoal
Gross consumption of charcoal is negative (Production + Imports – Exports + Stock changes + Statistical difference) because charcoal is produced from firewood, therefore production is shown in charcoal production item in the Transformation sector.
In this case charcoal balance is calculated as follows: Volume of charcoal produced in transformation sector + Imports – Exports + Stock changes + Statistical difference = Final consumption.
Transformation sector [renewable energy]
Indicates quantity of fuel consumed for the production of electricity and quantity of fuel consumed for the production of heat, which is sold. Indicates quantity of fuelwood consumed for the production of charcoal.
Final consumption [energy]
Consumption by industry, transport, households, agriculture, forestry, hunting, fishery, and other consumers (NACE Rev. 2 divisions 33, 36–39, 45–47, 52–96, 99).
Data collection and statistical processing
Survey method and data source
Data on production, imports, exports and consumption of renewable energy resources, charcoal and waste are are collected and compiled in accordance with Eurostat methodology "Renewables Annual Questionnaire". Data are acquired with calculations by using several data sources:
- CSB annual survey 1-energy "Report on production of heat and electricity";
- CSB annual survey 2-EK "Report on purchase and use of energy resources";
- Customs declarations on trade with third countries;
- INTRASTAT monthly survey of enterprises engaged in trade with EU Member States.
Includes all economically active enterprises, budgetary institutions, foundations, associations, funds (hereinafter – respondents) engaged in the production, imports, exports, consumption and sale of energy resources.
Consumption of fuel in sectors of national economy is found out by surveying State and local government enterprises of all sectors of national economy regardless the number of employed and by surveying all other enterprises employing 80 persons or more. Every year approximately 6 thousand respondents are surveyed. Data on enterprises and organisation employing less than 80 persons are acquired with the help of random sampling, and afterwards obtained information is extrapolated.
Total consumption is calculated as follows: production + imports – exports + stock changes + statistical differences
For the wood calculations following coefficients are used:
1 m3 solid = 2.5 m3 loose;
1 m3 solid = 0.7 tonne.
Data are compiled and calculated in compliance with:
- EU Combined Nomenclature;
- Statistical Classification of Economic Activities (NACE Rev. 2).
