1  The energy balance is derived from the energy sources balance sheet. Energy bearers are converted to energy units using the theoretical energy content of the energy bearers (their fuel value).
2  Electricity is treated as derived energy. Waterfalls are the primary energy source for the electricity produced in hydropower stations. The production in 2001 was 120 981 GWh. This corresponds to 436 PJ. It is estimated that an average of 15 per cent of the potential energy is lost in production.The calculated amount of produced hydro power energy (included the energy which is lost) becomes 436 PJ*100/85 = 513 PJ.
3  Line 7 is called 'Net domestic supply' to indicate that it is different from line 6 in the energy sources balance sheet. To avoid double counting and make it possible to read the balance horizontal, line 1.2. 'Production of derived energy beares' is not included in line 7.
4  Line 13 includes the theoretical energy content in energy beares delivered to domestic consumption. This is corresponding to line 13 in the energy sources balance sheet, multiplied with coefficients that express the theoretical energy content in the different energy sources.
5  Line 14 'Consumption as utilised energy' is showing how much of the energy that are actually utilised. The figures are calculated by multiplying the values in line 13 with the estimated thermal efficiency coefficients of the energy beares. It is estimated thermal efficiency coefficients for manufacturing, mining and quarrying, transport and 'other consumer groups ' for each energy bearer. Since the three main groups are very different, the coefficents expresses average figures. The thermal efficiency coefficents (and the losses) are very uncertain. The figures must therefore be considerated as estimates.
