1 Energy Efficiency Indicators: Fundamentals on Statistics Roberta Quadrelli Head - Energy Balances, Prices, Emissions, Efficiency Energy Data Centre Energy Statistics Training IEA, Paris, October 2014

2 Developing energy efficiency indicators: why?

3 The huge potential of energy efficiency IEA Energy Efficiency Market Report 2013

4 across the world

5 Indicators: key to set targets and monitor impacts

6 How to develop efficiency indicators?

7 Can balances help? Energy balances provide aggregated information on the country energy picture Definition of Total Primary Energy Supply (TPES) Efficiencies of transformation sector Definition of Total Final Consumption (TFC) and shares by sector/sub-sector Development of high-level indicators

8 A variety of high-level indicators Coupling energy balances data with various macro-economic variables

9 Understanding high-level energy indicators Source: IEA, TPES/GDP index, based on GDP PPP 2005 USD Energy intensity of the economy: TPES/GDP

10 For discussion. Is TPES/GDP an indicator of energy efficiency? 2. Yes 3. No 4. Maybe

11 Beyond balances: appropriate metrics for sound energy efficiency assessments + 15% - 35% 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. TC: Temperature Corrected.

12 .Energy balances do not provide enough information to monitor energy efficiency Residential: No breakdown by end use - space heating - space cooling - water heating - lighting - cooking - appliances Transport: No breakdown by segment - passenger / freight nor by vehicle type - Light duty vehicles / trucks,. Services: No breakdown by end use - space heating - space cooling - water heating - lighting - other equipment nor by category (hotels, restaurants, )

13 The need to collect more disaggregated data energy balances TPES/GDP TFC/Population Aggregated Indicators. energy efficiency data End-use efficiency indicators Process/appliance efficiency indicators data requirement Energy / tonne steel Space heating / floor area Energy /tonne clinker (dry process)

14 Introducing the IEA work to monitor energy efficiency

15 The IEA effort towards energy efficiency monitoring: data collection Available online As an answer to a request from IEA Ministers in 2009, the IEA designed a template to collect data for energy efficiency indicators. Now starting its fifth year of collection!

16 The IEA effort towards energy efficiency monitoring: methodological framework Being translated into Russian, Spanish, Chinese, Arabic Available online In response to requests from countries, and in parallel with a manual on indicators analysis

17 The manual on statistics for energy efficiency indicators

18 Providing a harmonized framework for data collection across sectors and end-uses

19 For discussion. What is the largest energy-consuming sector in the world? 2. Residential 3. Transport 4. Industry

20 Global final consumption by sector

21 Understanding where energy is used

22 For discussion. What appliances account for the largest share of energy consumption (OECD)? 2. Refrigerators/freezers 3. Dishwashers 4. Televisions

23 Different end-uses drive sectoral consumption

24 What is an energy efficiency indicator? generic energy efficiency indicator energy consumption activity

25 Presenting a set of indicators for each end use For each end use: Indicators pyramid 1 general 2 detailed 3 very detailed A smiley face indicates the recommended indicator

26 Summarizing energy and activity data needed Heating Cooling Water heating Lighting Cooking Systematic summary tables: indicators, energy and activity data

27 Describing common sources for data How do countries collect data? Four main types of methods

28 Methods used to collect data for indicators Administrative sources Surveys Metering and measuring Modelling

29 An online database of practices A platform to share expertise worldwide: practices are available in a searchable database. Share your practice!

30 For discussion. Is your country collecting data to monitor energy efficiency? 2. Yes, already 3. Not yet but planning 4. Not that I know of
