29 January 2024Energy self-reliance is an indicator that is looking at the amount of energy produced domestically in a given year and given country. It is a complements to the more traditional import dependency indicator that looks on how much energy was imported.
It looks on the share of domestic supply (production and recovered/recycled products) with respect to overall energy supply at the level of the top block of energy balances (i.e. aiming on the level of primary products and derived products imports; abstracting from energy convernsions/transformations and exports).
The limitation of this indicators is mostly with respect to energy substitutability, for example solid fossil fuels are not very suitable fuel for road vehicles and aviation; electricity cannot replace bitumen as construction material. Thus the overall economy needs have to be seen also from the persepctive of energy mix.
4.1. Data description
Energy self-reliance is calculated using the following ratio:
- numerator: primary production + recovered & recycled products
- denominator: primary production + recovered & recycled products + imports + stock draw
Resulting calculations are expressed as percentage and rounded to 2 decimal places.
Energy data are from Eurostat's dataset nrg_bal_s.
While this indicator could be in principle calculated for any fuel group, it is the most meaningful for the “Total of all fuels” which is shown in the database.
4.2. Unit of measure
[PC] Percentage
This indicator can have values between 0% and 100% only.
4.3. Reference Period
The calendar year (January - December)
4.4. Accuracy - overall
The indicator is produced according to the high-level quality standards of European Statistical System. While indirect indicators suggest overall accuracy of energy balance should be in general high, quantitative assessment of accuracy was not performed by Eurostat.

Comparability over time is ensured with a solid methodology harmonised on international level that is stable over long periods. Occasional breaks in time series are present due to the developments of statistical systems on national level and the level of detailed information (micro data) available at national level.
In general comparability is very high in last 10 years and for older periods slowly decreasing. In addition, introduction of new statistical information in the most recent data collections can lead to breaks in series until information is compiled and provided by reporting countries.
