Energy consumption in manufacturing industries

The purpose of the energy census for the manufacturing industry is to analyze volume and composition of the energy consumed by the manufacturing industry.

Data on energy consumption by manufacturing industry is provided bi-annually from 1980 and latest 2018, 2020, 2022 and 2024.

Statistical presentation

The energy census for the manufacturing industry covers all work places in industrial companies with at least 20 employees. That is equivalent to approximately 90 per cent of the energy consumption by manufacturing. It covers in principle the consumption of all energy sources in the production excl. external transport.

Statistical processing

Data is collected every two years from companies in industry and parts of the raw material extraction with at least 20 employees. The data undergoes a thorough error check, among other things to ensure correct unit statements and by comparing with the previous year. For workplaces subject to the CO2 quota scheme, the figures are compared with their reported energy consumption. The error-checked data is collected and adjusted by replacing missing information for 1-3 percent of the companies.

Relevance

The results from the energy census are used by Statistics Denmark to compile energy balances that are used in the national accounts.

Furthermore, the parties involved in energy planning, for instance municipalities, counties, the Energy Agency and affected supply companies, need the information.

A number of industrial associations, private companies and research institutes have also expressed an interest in the results. Furthermore, the energy census is used for energy statistics compiled by the International Energy Agency (IEA).

Accuracy and reliability

In general the quality of the statistics is good - especially main figures which builds on aggregates.

At a more detailed level, the results are more uncertain, mainly due to measurement errors.

Timeliness and punctuality

Results are published no later than eight months after the end of the reference period. Publications are released on time, as stated in the release calendar.

Comparability

Data on energy consumption by manufacturing industry is provided from 1980 and the concept has almost been kept since.

Time series can be found in The Statbank for the years since 2012.

Accessibility and clarity

These statistics are published yearly in a Danish press release, at the same time as the tables are updated in the StatBank. In the StatBank, these statistics can be found under the subject Energy consumption. For further information, go to the subject page.

Customised extracts from the statistics can be ordered. Researchers and other analysts from authorized research institutions can be granted access to the underlying microdata by contacting Research Services.
