The annual bilingual publication ‘Energy Balance Sheets 2009’ contains the data for 2004 - 2009 on energy statistics obtained from the current surveys of the National Statistical Institute.
The publication presents also detailed information on:
• Commodity energy balances - coal and coal products, crude oil and petroleum products, natural gas, renewables, electricity and heat
• Overall energy balance
• Primary energy production
• Gross inland energy consumption
• Transformation input/output
• Final energy consumption.
• Product definitions
• Energy balance indicators
• Specific conversion factors.
The overall energy balance sheets for 2008 and 2009 are presented in three matrixes:
• primary energy matrix;
• converted energy matrix;
• final energy consumption matrix,
according to the Eurostat’s methodology.
Transformation input in power and heat plants is included.
Tables with international comparisons for main energy indicators are included in publication. Data for these tables are taken from the publication of International Energy Agency - ‘Energy Statistics and Balances of Non-OECD Countries’ and ‘Energy Statistics and Balances of OECD Countries’, editions 2006, 2007, 2008, 2009 and 2010.
Data are presented in volume measures - tons, cubic meters, kWh etc. The common energy unit used for the Aggregated energy balance is ‘ton of oil equivalent’.
The following dependence exists between units:
1 GJoule = 0. 239 Gcal = 278 kWh = 0. 02389 toe
The publication is available on CD-ROM and is also published on the NSI website.
