This document summarizes a project conducted by the Danish Board of Technology examining possible paths for the future development of the Danish energy system. The project incorporated input from stakeholders across Danish political parties and energy sectors. Scenarios were developed to halve CO2 emissions and reduce oil consumption by 50% by 2025 through energy savings, increased wind and biomass, and electric vehicles. A combination scenario showing these targets can be achieved will undergo further stakeholder consultation to specify actions and measures for realization. The project aims to inform the European Commission's strategy for sustainable, competitive and secure energy.
