perspective• Some EVA results and implications for
biomass• Bottom-up versus top-down approaches• Vision: linking of energy systems model
with macro-economic perspective

The politics of energy supply
• Besides oil price other drivers of energy policy– supply stability– broader international security considerations– environmental aspects (modest role)
• Energy policy tightly regulated and subsidised– in EU a prerogative of the member states– large-scale subsidies for nuclear energy– some liberalisation to promote efficiency– not primarily an economic issue
• Considerable vested interests in energy sector

20-20-20: A new target in energy policy
• EU Council of Ministers, March 2007:– 20 per cent reduction of CO2– 20 per cent renewable energy– in 2020
• Denmark– negotiations on new energy policy stalled in
June 2006; have resumed now– EU requires 30 per cent renewables in DK in
2020, up from 15 per cent

Bottom-up energy sector modelling vs.top-down macro-economic perspective
• Bottom-up modelling is appropriate from a technical point of view to capture detail of energy system
• In case of non-marginal changes in energy system a need to understand broader macro-economic implications and feed-back on the energy sector itself– e.g. impacts in agricultural and forestry sectors– second-order impacts on economic growth,
employment etc.

Model availability for wider analysis of fossil-fuel phase-out
• RAMSES: Bottom-up model of Nordic energy sector of DK Energy Agency
• BALMOREL: Bottom-up model of Nordic-German energ sector
• EMMA: Energy-model as a satelitte model to ADAM; DK-macro-economic model
– general equilibrium model principles
• E3ME: Energy-Economy-Environment model of EU-27 including Denmark with high sector and fuel resolution
– econometric time-series estimated model
