    1. AssessingembeddedenergywithInput-Output Analysis…understandingenergydemandfrom a consumptionperspective

    2. Definition „Embeddedenergyisthecommercialenergythat was used in thework to makeanyproduct, bring it to themarket and dispose of it“

    3. Content • Introduction and objectives • Input-Output methodology • Results • Conclusions

    4. 1. Growingenergydemand Source: World Energy Outlook 2010, International Energy Agency Whatarethedrivers of ourgrowingenergydemand???

    5. 1. Drivers forenergydemand TheEconomy Agriculture Power sector • Consumptionpatterns • Consumptionlevels • Values Industry Transport Buildings Households Demandforgoods and services of people

    6. 1. Objectives • Change of viewpoint – consumptionbasedview Total demandforenergycanbetraced back to theconsumption of goods and services • Understandingdriversfrom a consumptionperspective • Provideinformationforconsumers and policymakers

    7. 1. Research Topic – Embedded Energy • Whatistheenergyrequirementfortheconsumption of goods and services? • Input Output Analysis

    8. 2. Input Output Model Domesticeconomy Output Input Imports from Rest of the World to domesticeconomy. ROW - economy

    9. 2. Input Output Model domesticproductionimportedintermediatesimported final goods

    10. 3. Embedded Energy in Austria 2007

    11. 3. Embedded Energy in Austria 2007 • Includesintermediategoods: • constructionwork • sewage and disposalservices • waterdistribution

    12. 3. Direct vs. Embedded Energy

    13. 3. Direct vs. Embedded Energy

    14. 3. Direct vs. Embedded Energy Global energydemandassumingAustrianconsumptionpatterns (govermentspending and investmentexcluded) ~ 200,000TWh Total Primaryenergydemand 2008 according to „World Energy Outlook“: 143,000TWh

    15. 4. Conclusions I • Itmakes sense to includeEmbeddedenergy in householdstudies • IfthewholeworldhadAustrianconsumptionlevelswewouldbe in trouble

    16. 4. Conclusions II • Input Output Analysis canbeused to provide a consumptionbasedview • High aggregationlevel and restriction to monetaryvaluesaredrawbacks • Fair method to identifyresponsibilityforenergydemand • Publication of such datawouldbehelpful to createawareness • Relevant dataforpolicymakers
