Energy intensity is one of the indicagtors to measure the energy needs of an economy. It is often used as an approximation of energy efficiency. Many factors influence energy intensity, for example it reflects on structure of the economy and its cycle, general standards of living and weather conditions in the reference area. This indicator can be used in monitoring of several strategies and programs.

4.1. Data description

Energy intensity is calculated as units of energy per unit of GDP. Indicator expressed in chain linked volumes is more suitable to be used to compare different time periods in one country, while PPS values are more suitable to be used to compare across countries in one specific year.

Energy data are from Eurostat's dataset nrg_bal_s and GDP data are from Eurostat's dataset nama_10_gdp.

nrg_bal_s:

• SIEC: TOTAL
• NRG_BAL: GAE
• UNIT: KTOE

nama_10_gdp:

• NA_ITEM: B1GQ
• UNIT: CLV05_MEUR, CLV10_MEUR, CLV15_MEUR, CP_MPPS_EU27_2020

Calculation examples:

Energy per GDP = 1000 * KTOE / CLV10_MEUR (Chain linked volumes, index 2010=100)
Energy per GDPPPS = 1000* KTOE / CP_MPPS (Current prices, million purchasing power standards)

Resulting calculations are rounded to 2 decimal places.

4.2. Unit of measure

KGOE_TEUR_PPS: Kilograms of oil equivalent (KGOE) per thousand euro in purchasing power standards (PPS)

• EI_GDP_PPS: Energy intensity of GDP in purchasing power standards (PPS)

KGOE_TEUR: Kilograms of oil equivalent (KGOE) per thousand euro

• EI_GDP_CLV05: Energy intensity of GDP in chain linked volumes (2005)
• EI_GDP_CLV10: Energy intensity of GDP in chain linked volumes (2010)
• EI_GDP_CLV15: Energy intensity of GDP in chain linked volumes (2015)

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.

6.3.2. Time Coverage - Comment

All  EU Member States have long time series; for some non-EU countries time series are shorter.

6.4. Comparability - over time

6.4.1. Comparability - over time - Grade

> 4 data points

6.4.2. Comparability - over time - Comment

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.
