• converted energy matrix;

• final energy consumption matrix,

according to the Eurostat’s methodology.

Transformation input in power and heat plants is included.

Data in tables concerning international comparisons are taken from:

• Eurostat Database - Energy Statistics/Quantity (nrg_quant)/Supply, Transformation, Consumption (nrg_10), http://epp.eurostat.ec.europa.eu/portal/page/portal/energy/data/database;

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.
