1 Energy Efficiency Indicators Overview The IEA energy efficiency indicators template Energy Statistics Training Paris, 4-8 March, 2013 Taejin Park Energy Efficiency Indicators

2 World Energy Outlook 2012 Greater efforts on energy efficiency would cut the growth in global energy demand by half by 2035

3 Overview What information is available from the energy balances? Which further data are needed? The IEA Energy Efficiency Indicators Template

4 Most countries collect basic energy statistics

5 which can be combined to build energy balances ENERGY BALANCE

6 The importance of energy balances WORLD ENERGY BALANCE Supply Transformation Energy dependency Efficiency of the energy sector Shares of energy consumption by sector Final consumption

and its limits No breakdown by end use: - space heating - water heating - lighting - cooking - air

7 and its limits No breakdown by end use: - space heating - water heating - lighting - cooking - air conditioning - appliances WORLD ENERGY BALANCE No breakdown by end use and by function of buildings (hospitals, schools, hotels, offices, restaurants, etc.) What most countries collect on a regular basis is limited to aggregated levels Coal & Peat Crude Oil Oil Products Gas Nuclear HydroGeoth/SolarComb.

8 Information from energy balance provides useful insights Share of Global TFC Other Transport Service Residential 23% Coal Oil Natural Gas 14% Solid Biofuel Other Transport Service Residential 24% Coal Oil Natural Gas 21% Solid Biofuel Industry Electricity 9% Industry Electricity 20% Mtoe Mtoe Electricity and natural gas account for 41% of global residential energy consumption in 2008; up from 23% in 1973

9 that can be coupled to macro-economic information to provide further insight on energy consumption patterns Index: 1990=1. Data for IEA18 (Australia, Austria, Canada, Denmark, Finland, France, Germany, Ireland, Italy, Japan, Netherlands, Norway, Slovakia, Spain, Sweden, Switzerland, UK, USA). Source: IEA energy balances.

10 but we need more data to understand the full story Index: 1990=1. Data for IEA18 (Australia, Austria, Canada, Denmark, Finland, France, Germany, Ireland, Italy, Japan, Netherlands, Norway, Slovakia, Spain, Sweden, Switzerland, UK, USA). Source: IEA energy efficiency indicators database. CC*: Climate Corrected. Data for space heating is also climate corrected.

Sectoral Energy Intensity End-use Energy Intensity Unit Energy Consumption Disaggregated Indicators Process/Appliance Efficiency data requirement Energy/ton cement Heating/sqm Litres/100km (stock) Dry process Condensing boiler Litres/100km What are the data needed to build a minimum set of disaggregated indicators?

13 THE IEA ENERGY EFFICIENCY TEMPLATE } Energy consumption and activity data

14 MACROECONOMIC DATA Structural activities Population Employment Dwellings Heating and cooling degree-days Exchange rate and purchasing power Final consumption GDP Value-added by sector

15 INDUSTRY Energy consumption by fuel type Oil and petroleum products Natural gas Coal and Coal Products Combustible renewables and waste Heat Electricity Other Value-added 19 Major ISIC subsectors ISIC Agriculture, hunting, fishing and forestry ISIC Mining and quarrying ISIC Manufacturing (each sub-sector individually) ISIC Electricity, Gas and Water ISIC 45 Construction Derived indicators: Energy/value-added

16 COMMODITIES PRODUCTION Physical production for major manufacturing sub-sectors ISIC 21. Paper and paper products ISIC 24. Chemicals and chemical products ISIC 26. Other non-metallic mineral products ISIC 27. Basic metals Efficiency indicator: Energy Intensity: energy use/production

17 SERVICES Energy consumption by fuel type Climate corrected End-uses Space heating Space cooling Lighting Other building energy use Non-building energy use (e.g. street lighting) Floor space Derived indicators: Energy consumption/floor space Energy consumption/value-added

18 RESIDENTIAL End-uses Space heating Space cooling Water heating Cooking Lighting Fuel consumption by fuel type Climate corrected Appliance stock Appliances Refrigerator Freezer Dishwasher Clothes washer Clothes dryer TV Computers Appliance diffusion Units per dwelling Efficiency indicators Energy consumption per unit Energy per floor area

19 TRANSPORT What is Energy Efficient Transport? Transport MORE and FURTHER with LESS fuel consumption Use public transport instead of personal cars

20 TRANSPORT What is Energy Efficient Transport? Transport MORE and FURTHER with LESS fuel consumption Use public transport instead of personal cars We need ACTIVITY data in addition to fuel consumption data

21 TRANSPORT Fuel consumption by fuel type Transport by modes & purpose Activity and Structure Stock of vehicles Vehicle-kilometres Passenger-kilometres Tonne-kilometres Efficiency indicators Energy per passenger-kilometre Energy per tonne-kilometre

22 TRANSPORT What is not included? Off-road (e.g. construction vehicles, agriculture vehicles) Military Fishing vessels Pipelines International transportation

23 PRE-FILLED TIME SERIES Pre-filled time series Space Heating Space Cooling Water Heating Cooking

24 COVERAGE STATUS A report on the coverage status is automatically updated when new data are entered.

25 PLOTTING Various options offered for plotting indicators

26 COMPARING Possibility to compare indicators

27 The IEA template: 1) provides a starting point for data collection

28 The IEA template: 2) helps identifying data gaps and issues

29 Data quality checks Internal consistency Consistency with IEA energy balances Plausibility Gross vs Net Calorific Value Coverage / definitions We try to understand why to help countries overcome the difficulties they face in providing quality data

development of energy efficiency indicators To collect best practices from IEA member countries and beyond

30 A manual on Statistics for Energy Efficiency Indicators The IEA is developing a Manual on Statistics for Energy Efficiency Indicators To help countries to collect energy end-use and activity data for the development of energy efficiency indicators To collect best practices from IEA member countries and beyond In cooperation with the ODYSSEE network, APEC, countries, companies and associations Release expected in Fall 2013

31 CONCLUSIONS Obtaining detailed end-use data is crucial. New but countries are making a big progress. IEA Energy Efficiency Indicators (EEI) Database Data for 1990 to 2009 for IEA countries Most IEA countries already implemented EEI database Very broad interest (UN, WB, APEC, EC...)

32 CONCLUSIONS The IEA Energy Efficiency Indicators Template is a useful tool to start collecting these data! Thank you for your attention energyindicators@iea.org
