  1. Introduction to Energy Indicators Introduction to Energy Indicators Motivation and Approach Motivation and Approach Fridtjof Unander International Energy Agency CSD 14 4 May 2006 AGENCE INTERNATIONALE DE L’ENERGIE INTERNATIONAL ENERGY AGENCY

  2. Assessing Energy Efficiency Progress: A call for action from G8 Leaders and IEA Ministers � Gleneagles Plan of Action (G8 Communiqué): We will [G8 Heads of States]….invite the IEA …to develop energy indicators to assess efficiency… � Communiqué from IEA Ministers May 2005: “…instruct the IEA to monitor our efforts to [reinforce our energy efficiency effort]…” AGENCE INTERNATIONALE DE L’ENERGIE INTERNATIONAL ENERGY AGENCY

  3. Presentation Overview Presentation Overview � Why indicators? � What are they? � Examples � Data needs AGENCE INTERNATIONALE DE L’ENERGIE INTERNATIONAL ENERGY AGENCY

  4. Why Indicators? Why Indicators? Indicators can help... � Understand driving forces behind growth in energy demand � Separate factors related to energy efficiency from those that are not � Identify potentials for energy efficiency improvements � Measure progress of energy efficiency measures AGENCE INTERNATIONALE DE L’ENERGIE INTERNATIONAL ENERGY AGENCY

  5. What is an Energy Indicator? What is an Energy Indicator? � Relates energy use to activities driving demand for energy services � Two main types: 1.Indicators following activities that drive energy use (e.g. industrial output, building area, appliance ownership, ton-km, car-ownership and use) 2.Indicators following energy intensity developments: (e.g. energy/passenger-km, energy/value added by industry branch, space heating energy/floor area) AGENCE INTERNATIONALE DE L’ENERGIE INTERNATIONAL ENERGY AGENCY

  6. Example of Driving Force Example of Driving Force Car Ow nership and Income 1970- -2000 2000 Car Ow nership and Income 1970 0.8 0.7 Oil Car Ownership (vehicle/capita) 0.6 Crises & US Climate Challenges Italy 0.5 Australia Sweden 0.4 France Finland 0.3 UK Norway 0.2 Netherlands OF ENERGY USE IN IEA COUNTRIES Denmark 0.1 Japan 0 5 7 9 11 13 15 17 19 21 23 Personal Consumption Expenditures per Capita (1000 1995 US$, PPP/capita) Strong growth most places, slowly leveling off in the US
