concepts
Concepts
  • Reference link between energy and growth
    • (dE/dt) /Et = (dY/dt)/Yt
  • Absolut delinking
    • (dE/dt) /Et > (dY/dt)/Yt
  • Relative delinking
    • 0 < (dE/dt) /Et < (dY/dt)/Yt
  • Constant energy consumption?
    • A question of ≥ or ≤

Anders Chr. Hansen

endogenous or planned delinking
Endogenous or planned delinking?
  • Environmental Kuznets curve
    • Anti-green movement in the first half of this decade
    • Automatic / endogenous delinking
    • Relax, cool down, problem will be solved by itself
  • Exogenous, planned delinking
    • Delinking is an option (as well as linking)
    • High political priority in the EU and memberstates

changes in industrial structure
Changes in industrial structure
  • Earlier studies agree:
    • Changes in industrial structure has little to say
  • This study:
    • It is not because changes are small, but because they work in opposite directions

Anders Chr. Hansen

dematerialisation endogenous delinking
Dematerialisation (endogenous delinking)
  • Observed trend: Lessweight of energy intensive primary (agriculture and fisheries) and secondary (cement, glass, steel, chemical, paper) industries
  • But onlyone out of many trends, e.g., more transport, oil and gas extraction
  • In DK alsoincreasingoil and gas productioncontributes to observeddelinkingbecause VA/GJ is aboveaverage
  • The crucialquestion is about the sum of all the trends
  • Delinking in Denmark primarily a result of long term energy policy since the 70s: Energy savings, combining heat and power production, usingrenewableenergyresources
