For 2006 the consumption of fuel wood and kerosene in cottages is included in the households energy consumption while this is excluded for earlier years. To obtain a comparable development, 2004-figures are calculated and presented in the same way as in 2006 in this column. The difference makes up less than 1 per cent of the total energy consumption in 2004. Electricity consumption in cottages is not included for any years.

The income is measured in firm NOK in 2004.
