EARTHTRENDS DATA TABLES For more information, please consult http://earthtrends.wri.org TECHNICAL NOTES: ENERGY CONSUMPTION BY SECTOR DEFINITIONS AND METHODOLOGY Total Final Consumption (TFC) is the sum of consumption by the different end-use sectors. TFC does not include the energy used by the transformation industries and the energy losses in converting primary energy into a useable form for the final consuming sectors. Non-energy use of such oil products as white spirit, lubricants, bitumen, and paraffin waxes is included in TFC. Petrochemical feedstocks and backflows from the petrochemical industry are not included. The total amount of primary energy refers to the energy consumed from all sources including fossil, nuclear, hydroelectric, modern renewables, traditional renewables, and all renewable fuels and waste. Basic energy statistics are collected by the International Energy Agency (IEA) from a variety of sources. In OECD member countries, national administrations fill out five annual questionnaires. In non-OECD countries, statistics are collected from questionnaires, international organizations such as United Nations, co-operation with national statistical bodies, and direct communication with energy consultants and companies. If data are not available from any of these sources, they are estimated by the IEA. The IEA measures the heat content of all energy commodities in metric tons of oil equivalent (toe). One toe is equal to 10 Exp. 7 kilocalories, 41.868 gigajoules, or 11,628 gigawatt-hours (GWh). A toe measures the energy contained in a metric ton (1000 kg) of crude oil. Energy Consumption by Sector is the percentage of TFC consumed by a designated sector, as defined by the International Secretariat for Industry Classifications (ISIC). For a complete listing of the economic activities included in these ISIC divisions, please consult the web page of the U.N. Department of Economic and Social Affairs, Statistics Division: http://unstats.un.org/unsd/cr/registry/regcst.asp?Cl=17&Lg=1. Industry includes a combination of all industrial sub-sectors, such as mining and quarrying, iron and steel, and construction. Energy used for transport by industry is not included here, but is reported under transportation. Road Transport includes all fuels used in road vehicles, including military, as well as agricultural and industrial highway use. The sector excludes motor gasoline used in stationary engines and diesel oil used in tractors. All Other Transport refers to all fuel used for non-road transport except fuel used for international marine bunkers and ocean, coastal, and inland fishing. It includes transport in the industry sector and covers railway, air, internal navigation (including small craft and coastal shipping not included under marine bunkers), fuels used for transport of materials by pipeline and non-specified transport. Agriculture includes all activities defined as agriculture, hunting, and forestry. The sector therefore includes energy consumed by ocean, coastal and inland fishing in addition to the energy consumed by traction, power, and heating. Commercial & Public Services include, for example, wholesale and retail trade; the operation of hotels and restaurants; post and telecommunications; real estate, renting and business activities; the collection, purification and distribution of water; maintenance and repair of motor vehicles and motorcycles; financial intermediation, except insurance and pension funding; computer and related activities; sewage and refuse disposal; public administration and defense; education; and other community, health, social and personal service activities. Residential includes all energy used for activities by households except for transportation. Non-energy Uses and “Other”[SA1] includes the use of petroleum products such as white spirit, paraffin waxes, lubricants, bitumen and other products. It is assumed that these products are used exclusively for non-energy purposes. This category also includes the non-energy use of coal (excluding peat) and fuel inputs for the production of ammonia and methanol. All fuel use not elsewhere specified is included here. FREQUENCY OF UPDATE BY DATA PROVIDERS Data sourced from IEA cover the years 1960-2001 for countries that are members of the Organization for Economic Cooperation and Development (OECD). Data sourced from IEA for OECD non-members are typically from 1971 to 2001, but coverage varies. The IEA updates energy data each year in June for OECD countries and in September for non-OECD countries, often revising data from earlier years. DATA RELIABILITY AND CAUTIONARY NOTES The energy balances data are primarily based on well-established and institutionalized accounting methodologies, and are therefore considered reliable. The data as received from the provider do not distinguish between no data and zero values. WRI has distinguished between the two where possible, but some values represented as zero should probably be indicated as missing and vice versa. SOURCE International Energy Agency (IEA), 2003.
