It is technically possible to construct an energy system which is not based on coal, oil and natural gas. This has been confirmed in a report issued by the Danish Energy Agency entitled "Energy Scenarios for 2020, 2035 and 2050", which calculates the additional costs of an energy supply independent of fossil fuels at between DKK 6 and 29 bn. in 2050, depending on the choice of green energy system.

The parties behind the energy agreement agreed in 2012 to draw up five energy analyses of:

• The electricity grid
• District heating
• Bioenergy
• Biogas 
• The gas infrastructure

The analyses are to contribute to ensuring that conversion of the energy system to renewable energy is as cost-effective as possible. As a supplement to the sub-analyses, an energy-scenario report has been prepared which comprises a common analysis framework, aiming at ensuring cohesion between the different sub-analyses.

The energy-scenario report confirms that, as the conversion will take time, shortly after 2020 it will be necessary to decide whether the future energy system is to be an electricity-based wind-power system or a fuel-based biomass system. A wind-based fully electrified system will have good fuel supply security, but will be challenged in terms of security of electricity supply. On the other hand, a bioenergy-based system will require large imports of biomass and it will be challenged in terms of fuel supply security and sustainability.
