Indicator Assessment
Over the period 1990-2009, in EU-27 countries, energy efficiency in industry has improved by 30% at an annual average rate of 1.8% per year, with large differences among countries. Energy efficiency improvement has been realized in all industrial branches except textile. Over the period 2005-2009 energy efficiency improved by 1.5%/year with an important deterioration in 2009 due to the economic crisis.
Energy efficiency index (ODEX) in the EU-27
Note: Energy efficiency index of industry (ODEX) is a weighted average of the specific consumption index of 10 manufacturing branches; the weight being the share of each branch in the sum of the energy consumption of these branches in year t and the sum of the implied energy consumption from each underlying industrial branches in year t (based on the unit consumption of the sub-sector with a moving reference year).

Benchmarking in the steel industry
Note: Figure shows a more detailed comparison of the performance (in terms of energy unit consumption) of the European steel sector across the different EU-27 countries taking into account the relative share of electric steel in total crude steel production.

Benchmarking in the cement industry
Note: Figure compares the energy unit consumption of cement in EU countries as a function of the share of clinker: the higher this ratio, the higher the specific energy consumption.

Benchmarking in the pulp and paper industry
Note: The figure displays the unit energy consumption per ton of paper as a function of the ratio pulp production to paper production: the higher the ratio, the higher the energy unit consumption.

When analyzing specific energy consumption trends in industrial branches, one has to account for the specificities in terms of process mix and product mix. For steel, there are basically two main production processes: the blast furnace oxygen process and the electric arc furnace process. The first one, which represents about 2/3 of the crude steel production for only 1/3 for the electric arc furnace, is much more energy intensive. For paper and cement, part of the energy intensive component, pulp and clinker respectively, may be imported instead of being produced in the country, which will reduce the unit energy consumption, all things being equal[1].
[1] The mix of process to produce the clinker (wet versus dry process) or the paper pulp (chemical versus mechanical pulp) is another explanatory factor of the differences observed but due to lack of data it has not been quantified here.

The variation of the weighted index of the unit consumption between t-1 and t is defined as follows:
It -1/It = SUMi ECi,t *(UCi,t/UCi.t-1)
with : energy share EC i (consumption of each branch i in total industry consumption); unit consumption index UC i (ratio : consumption related to production index or ratio : consumption related to physical production of steel, cement and paper)
t refers the current year, t-1 to the previous year
The value at year t can be derived from the value at the previous year by reversing the calculation:It /It -1= 1/( It -1/It)
ODEX is set at 100 for a reference year and successive values are then derived for each year t by the value of ODEX at year t-1 multiplied by It /It -1
CO2 emissions from energy uses split between direct emissions and indirect emissions:
Indirect CO2 = E ind/E tot * CO2 ie
with E : electricity consumption (indfor industry, tot for all sectors) (source ODYSSEE database);
CO2 ie : CO2 emissions from public electricity and heat production ( source EEA, inventories 2009)
Geographical coverage:
The Eurostat database covers all 27 EU member states plus Iceland, Norway, Switzerland, Croatia and Turkey. Odyssee database covers EU-27 plus Norway and Croatia. Not always data is available for all countries.
Temporal coverage:
1990-2009 with a focus on the period 2000/2009 for detailed analysis by country (due to data non available or reliable for new EU countries before 2000).
Methodology and frequency of data collection:
Data collected annually in the framework of the ODYSSEE MURE project
Methodology of data manipulation:
More information on ODYSSEE available on the website http://www.odyssee-indicators.org
- Cement :
o physical production: sum of the production of the 27 countries (source Odyssee)
o energy consumption : based on the energy consumption of 12 countries (10 EU-15 countries: uk, swe, esp, prt, nld, ita, grc, fra, rfa, bel) + Poland and Hungary (source Odyssee), which is extrapolated for EU-27, based on the share of production these 12 countries in the total production of cement (consumption EU-27= consumption 12* (production EU-27/production 12)).
- Paper
o physical production for EU-27 is the sum of EU-27 countries (source Odyssee)
o energy consumption : source Euro stat
- Steel :
o physical production for EU-27 is the sum of EU-27 countries (source IISI)
o energy consumption : source Eurostat
No methodology references available.
No uncertainty has been specified
Not all data is available for all countries. Availability for data on years earlier than 2009, is higher.
Odyssee data is recently updated (October 2011)
The reliability of total industry energy consumption and related CO2 emissions is reliable due to trustworthy statistics underlying it.
No uncertainty has been specified
