Comparability

Comparability - geographical

The statistics follows international standards and has a high degree of comparability with other international statistics that follow the same acknowledge international principles.

Comparability over time

The energy accounts are available in a comparable form back to 1966, which allows for consistent time series analysis. The energy accounts from 2008 and onwards are based on data sources based on the Danish Industry Classification of All Economic Activities 2007 (DB07), whereas the accounts for the years from 1966-2007 are based on calculations on an older set of accounts. In the calculations it has been attempted to make the necessary adjustments in order to comply with new industry classifications. From the reference year 2016 the product 'diesel' only includes diesel used for road transport while stocks, imports and exports are includes in 'gasoil'.

The energy accounts has been published with monetary values until the reference year 2016. These figures were to a large extent based on models without primary sources. Hence it has been decided to discontinue the publication.

In relation to the publication of the energy accounts 20 November 2013 the energy accounts have been revised. During the revision process emphasis has been put on ensuring comparability and consistency over time.

Coherence - cross domain

The energy accounts are based on the same definitions and classifications as the national accounts.

With the revision of the energy accounts a new allocation of the production of electricity and district heat has been introduced. Electricity is now produced by 350010 Production and distribution of electricity and by 383900 Sewerage; waste collection, treatment and disposal activities etc. District heat is produced by 350010 Production and distribution of electricity, 350030 Steam and hot water supply, and by 383900 Waste management and materials recovery.

Other energy statistics, for instance the Danish Energy Authorities energy statistics accounts for the consumption of energy, which can be classified by both Danish residents as well as by non-residents within the Danish territory. The Danish Energy Authorities energy statistics is based on the guidelines from the International Energy Agency (IEA).

Compared to other energy statistics this implies that the energy accounts based on the national accounts principles also include the consumption of energy caused by international transport activities carried out by Danish residents. That is, the consumption of fuels for Danish operated vehicles, planes and ships abroad are included in these energy accounts. Diesel, jet petroleum and fuel oil purchased abroad are indicated a separate products.

Coherence - internal

Internal data consistency is good. Before each new data release of the energy accounts, the data is validated to be consistent with the final national accounts.
