Energy Transition in Austria: Designing Mitigation Wedges

EU climate and energy policy defines ambitious objectives for the Member States, requiring a fundamental change in energy systems. In an interdisciplinary approach, starting with welfare-generating energy services instead of energy flows, we analyse restructuring options for the Austrian energy system. We extend the concept of stabilization wedges by Pacala and Socolow and integrate technological and behavioural options into a structural energy model, complemented by an economic evaluation in an input-output analysis. We apply the energy service based approach to a transformation of the Austrian energy system that meets the EU 2020 emission targets. We estimate that this would require on average additional investment of about 6 billion € p.a. over a twelve year period. This investment allows to tap savings in operating costs (predominantly energy costs) of up to 4.3 billion € at the end of the period, when using a conservative assumption of non-rising energy prices.
