CHANGES FROM LAST EDITION Countries Latvia became an OECD Member in July 2016. Accordingly, Latvia now appears in the list of OECD Members and is included in the zone aggregates for data starting in 1990, starting with the 2017 edition.

3 Prior to 1990, data for Latvia are included in Former Soviet Union.

DATABASE STRUCTURE The database ENERGY STATISTICS of OECD countries includes annual data for: countries: 35 countries and 5 regional aggregates (see section 4: Geographical coverage); years: 1960-2015, unless otherwise specified. The database includes the following two files: ENERGY STATISTICS ENERGY STATISTICS in matrix form (68 products; 88 flows) (various natural units, depending on the product); Electricity and heat output by type of producer (12 flows) (GWh; TJ).

4 Conversion factors of OECD countries: net calorific values by flow (14 flows) for 15 coal, peat, oilshale products (toe/t; kJ/kg); average net calorific values for 23 oil products and 4 biofuel products (toe/t; kJ/kg); volume to mass ratio for 22 oil products and 3 biofuel products (barrels/tonne). 6 - WORLD ENERGY STATISTICS (OECD COUNTRIES): DATABASE DOCUMENTATION (2017 PRELIMINARY edition) INTERNATIONAL ENERGY AGENCY 3. FLOW DEFINITIONS Supply Flow Short name Definition Production INDPROD Refers to the quantities of fuels extracted or produced, calculated after any operation for removal of inert matter or impurities ( sulphur from natural gas).

5 For other hydrocarbons (shown with crude oil), production should include synthetic crude oil (including mineral oil extracted from bituminous minerals such as oil shale and tar sands, etc.). Production of secondary oil products represents the gross refin-ery output. Secondary coal products (including coal gases) represent the output from coke ovens, gas works, blast furnaces and other trans-formation processes. From other sources coal OSCOAL Refers to both primary ENERGY that has not been accounted for under production and secondary ENERGY that has been accounted for in the production of another fuel.

6 For example, under primary coal: recov-ered slurries, middlings, recuperated coal dust and other low-grade coal products that cannot be classified according to type of coal from which they are obtained; under gas works gas: natural gas, refinery gas, and LPG, that are treated or mixed in gas works ( gas works gas produced from sources other than coal). From other sources - natural gas OSNATGAS Refers to both primary ENERGY that has not been accounted for under production and secondary ENERGY that has been accounted for in the production of another fuel.

7 From other sources - oil products OSOIL Refers to both primary ENERGY that has not been accounted for under production and secondary ENERGY that has been accounted for in the production of another fuel. For example, under additives: benzol, al-cohol and methanol produced from natural gas; under refinery feedstocks: backflows from the petrochemical industry used as refin-ery feedstocks; under other hydrocarbons (included with crude oil): liquids obtained from coal liquefaction and GTL plants. From other sources - renewables OSRENEW Refers to both primary ENERGY that has not been accounted for under production and secondary ENERGY that has been accounted for in the production of another fuel.

8 WORLD ENERGY STATISTICS (OECD COUNTRIES): DATABASE DOCUMENTATION (2017 PRELIMINARY edition) - 7 INTERNATIONAL ENERGY AGENCY Supply Flow Short name Definition From other sources - non-specified OSNONSPEC Refers to both primary ENERGY that has not been accounted for under production and secondary ENERGY that has been accounted for in the production of another fuel. This flow is used if the source is not known. Imports IMPORTS Comprises amounts having crossed the national territorial boundaries of the country whether or not customs clearance has taken place.

9 For coal: Imports comprise the amount of fuels obtained from other countries, whether or not there is an economic or customs union be-tween the relevant countries. Coal in transit should not be included. For oil and natural gas: Quantities of crude oil and oil products imported under processing agreements ( refining on account) are included. Quantities of oil in transit are excluded. Crude oil, NGL and natural gas are reported as coming from the country of origin; refinery feedstocks and oil products are reported as coming from the country of last consignment.

10 For electricity: Amounts are considered as imported when they have crossed the national territorial boundaries of the country. If electricity is wheeled or transited through a country, the amount is shown as both an import and an export. Exports EXPORTS Comprises amounts having crossed the national territorial boundaries of the country whether or not customs clearance has taken place. For coal: Exports comprise the amount of fuels supplied to other countries, whether or not there is an economic or customs union be-tween the relevant countries.
