  3. Sustainable development?

  4. Required eco-efficiency progress

  5. 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

  6. 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 Anders Chr. Hansen

  18. 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

  19. 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 Anders Chr. Hansen

  20. From central powerplants towards distributed heat and power and renewable energy Central elproduktion in midt-80’erne Central og decentral elproduktion i dag • Decentral kraftvarme • Central kraftvarme • Vindmøllepark
