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 ltgt 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 efficiency is 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

8
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

Energy efficiency trends for industry Energy
efficiency progress 12 in the EU15 increased
gain since 1997
Revised indicator
10
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)

11
Energy efficiency trends for households About 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
12
Energy efficiency index for transport

• Calculated on 7 modescars, 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

13
Energy efficiency trends for transportRegular
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
14
Energy efficiency index and final energy
intensity EU-15
More regular trend for the index Depending on the
period different trends
15
Progress of energy efficiency index and final
energy intensity (1990-2002)
16
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

17
The efficiency index is not only a descriptive
indicator, but an explanatory indicatorEnergy
consumption change per dwelling in the EU15
18
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)

19
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

20
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

21
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
