  1. SAVE-ODYSSEEMONITORING TOOLS FOR ENERGY EFFICIENCY IN EUROPE Energy efficiency index ODEX B Lapillonne,, K Pollier , Enerdata D Bosseboeuf, ADEME Septembre 2004

  2. Why energy efficiency indices? • Provide more relevant indicators for energy efficiency evaluation of final consumers at the overall level or at sectoral level (industry, households, transport) • Therefore, provide alternative indicators to the indicators currently used (energy intensity for all final consumers, for industry and for transport; consumption per dwelling for households) ,that include the influence of many factors not linked to efficiency (structural changes, lifestyles,…)

  3. Energy efficiency index at sectoral level • For industry, transport and households : aggregation of unit consumption indices by sub-sector(or end-use / equipment) in one index for the sector on the basis of the weight of each sub-sector in the sector consumption • Unit consumption by sub-sector can be expressed in different units so as to be as close as possible to energy efficiency evaluation : toe/ dwelling, kWh/appliance, toe/ton, litre/100km ; • Energy efficiency improvement<=> index decreases (e.g 85 in 2000  15% energy efficiency improvement

  4. Energy efficiency index for final consumers: Odex • Odex calculated by weighting each sectoral index with the share of each sector in the final energy consumption (26 sectors used: 7 in transport, 9 for households and 9 in industry, 1 in services) • Odex above all based on statistics • Odex a detailed top down approach • Odex to be extended to total consumption (ie including transformations)

  5. Energy efficiencyis regularly improving:0.8%/year between 1990 and 2002 in the EU 15; larger gains in industry with 1.1%/ yr ; no progression for households since 1996

  6. Energy efficiencyis improving all countriesEnergy efficiency gain 1990- 2002

  7. Energy efficiency index for industry • Evaluation carried out at the level of 9 branches: • 4 main branches: chemicals, food, textile & leather and equipment goods; • 3 energy intensive branches: steel, cement and pulp & paper • 2 residual branches: other primary metals ( ie primary metals minus steel), other metallic minerals ( ie non metallic mineral minus cement) • Unit consumption expressed in terms of energy used • per ton produced for energy intensive products(steel, cement, and paper) • per unit of production index for the other branches

  8. Energy efficiency trends for industry Energy efficiency progress : 12% in the EU15 ; increased gain since 1997 Revised indicator

  9. Energy efficiency index for households • Calculated on 8 end-uses/appliances : heating, water heating, cooking, 5 large appliances (refrigerators, freezers, washing machine , dishwashers and TV) • Indicators used: • Heating: unit consumption per m2 at normal climate (toe/m2) Water heating: unit consumption per dwelling with water heating Cooking: unit consumption per dwelling Large elec. appliances: specific consumption per appliance (kWh/year)

  10. Energy efficiency trends for householdsAbout 10 % energy efficiency progress between 1990 and 1996 in the EU15 ; no progress since; regular improvement for large appliances Calculated over 8 end-uses and appliances

  11. Energy efficiency index for transport: • Calculated on 7 modes:cars, trucks & light vehicles, air (domestic), rail, water, motorcycles and buses • Indicators used:  cars: specific consumption in litres/km trucks & light vehicles: unit consumption per ton-km air : unit consumption per passenger-km rail ,water : unit consumption/pkm or tkm  motorcycles, buses: toe/vehicle

  12. Energy efficiency trends for transport:Regular energy efficiency improvement in the EU 15 since 1993 ( 0.7% year); light slow down since 1999 because of road transport of goods Calculated over 7 modes of transport

  13. Energy efficiency index and final energy intensity: EU-15 More regular trend for the index Depending on the period different trends

  14. Progress of energy efficiency index and final energy intensity (1990-2002)

  15. Yearly variation of energy efficiency index, final energy intensity and GDP: role of business cycles Efficiency index less sensitive to business cycles All indicators at normal climate

  16. The efficiency index is not only a descriptive indicator, but an explanatory indicatorEnergy consumption change per dwelling in the EU15

  17. Energy efficiency index: conclusion • The energy efficiency index Odex is already available for all EU-15 countries and Norway • It is calculated with the same methodology on the basis of the same indicators for each country, developed in a consensual way within the ODYSSE project • Used by all participants: national report on energy efficiency trends and energy efficiency profiles (available on www.odyssee-indicators.org). • Odex will be extended to the total consumption, including energy transformations • Can be easily extended to new EU members (www.ceec-indicators.org)

  18. Annex 1 Coverage of the ODEX by country • 25 to 26 indicators are used for the EU15 and 8 countries (Austria, Denmark, France, Germany, Greece, Italy , Netherlands, UK) (7 in transport, 9 for households and 8/9 in industry, 1 in services ) • 17-18 indicators for Finland, Spain, Sweden and Norway (main difference is the large appliances or details by road vehicles). • 15 indicators for Belgium, Ireland Portugal and Luxembourg

  19. Annex 2: Energy efficiency index for transport :alternative calculation • Calculated on 4 modes: road, air (domestic), rail, water • Indicators used: •  road: unit consumption per car equivalent trucks & light vehicles: unit consumption per ton-km air : unit consumption per passenger-km rail ,water : unit consumption/pkm or tkm • Countries:Belgium, Ireland ,Portugal, Sweden, Luxembourg

  20. Annex 3 Energy efficiency index for households : alternative calculation • Calculated on 2 end-uses: heating , water heating Heating: unit consumption per m2 at normal climate (toe/m2) Water heating: unit consumption per dwelling with water heating Case of :Spain, Sweden, UK , Finland, Greece, Norway • Calculated on total consumption (without end-use) : Unit consumption of fossil fuels (non electric) per m2 at normal climate (toe/m2) Case of : Belgium, Ireland, Portugal, Luxemburg

  21. Annex 4: Energy efficiency index Example of calculation IE90 = 100 IE91 = IE90 x (98 x 0.60 + 107 x 0.40 = 102 IE92 = IE1991 x (95/98 x 0.59 + 113/107 x 0.41) = 102 IE93 = IE1992 x (90/95 x 0.55 + 115/113 x 0.45) = 100

  22. Energy efficiency and final energy intensity: France More regular trends for the index All indicators at normal climate
