Sustainable development?


Required eco-efficiency progress


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?

  • 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

  • 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)

  • 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


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
