  1. Chapter 5 – Energy Flows Results of the second worldwide consultation

  2. Chapter contents • Introduction (1%) • Concept of energy flows (8%) • Definition of main energy flows (17%) • Energy industries (47%) • Other energy producers (6%) • Energy consumers and energy consumption (21%)

  3. Chapter objective: “Describe energy flows and the main groups of economic units that are relevant for such flows.” (5.1)

  4. A – Introduction Chapter objective B – Concept of energy flows Meaning of the term ‘energy flow’ Diagram of main energy flows Main groups: energy industries, other energy producers and energy consumers. C – Definition of main energy flows

  5. ‘Main energy flows’ diagram of Section B

  6. D – Energy industries Definition of energy industries Description of each activity Discussion of electricity and heat Discussion of transformation processes E – Other energy producers Definition of other energy producers Recommendation on when to include them F – Energy consumers and energy consumption Definition of energy consumers Uses of energy Cross-classifying uses and users Energy industries according to IRES: “Economic units whose principal activity is the primary energy production, transformation of energy and distribution of energy” (5.24) Energy consumers according to IRES: “Economic units in their capacity as final users of energy: they use energy products for energy purposes and/or for non-energy purposes” (5.72) Other energy producers according to IRES: “Economic units engaged in the production, transformation and transmission/distribution of energy as a secondary and/or ancillary activity […]” (5.66)

  9. Result of the WWC - summary Q.1: Do you overall agree with the contents of this chapter? Q.2: Do you agree with the description of the main energy flows? Q.3: Do you agree with the description of the energy industries? Q.4: Do you overall agree with the description of the energy consumers and energy consumption?

  10. WWC – comments received • 85 comments received • From the comments we have identified • 21 issues for which we need the opinion of the Expert Group; and • 17 ‘straightforward’ issues (editorial and other) for which the Expert Group is also invited to comment.

  11. Some fundamental issues raised • Transportation • Relationship with other chapters • some suggested merging Ch. 5 and Ch. 8 • others suggested merging Ch. 5 and Ch. 6 • also, some suggested to keep chapters separate, but move material directly related to energy balances to Ch. 8.

  12. Discussion A list of issues brought up by the respondents to the 2nd WWC has been prepared and presented to the Expert Group. Members of the expert group are invited to provide their opinions on the presented issues.
