This report presents the roadmap to meet research based-strategy of a cost-effective and energy-efficient energy system in Europe in 2050. The roadmap is based on the assessment of the energy efficiency first principle within the context of current energy systems as well as a transition towards a cost-effective 100% renewable energy systems for the EU27 and the United Kingdom in 2050, further called the sEE 1.5 scenario. The roadmap also presents a path that enables short-term energy security by phasing out import dependency of Russian natural gas in 2030 (sEE 2030 scenario), while still enabling a path that enables achieving 100% renewable energy in 2050.
The novelty of the roadmap is the investigation and quantification of energy efficiency measures for each of the three sectors transport, industry, and buildings, combining spatial analytics country-specific information and energy grids costs for 27 EU Member states and UK. Towards sEE 2030 we focus on well-known developed technologies, while in the period from 2030 to 2050 sEE 1.5 energy system assumes further developments in cost reductions and efficiency e.g., for wind, hydrogen and PV. This report mainly focuses on 2050 and the back casting of the 2030 step towards that. In the parallel report “REPowerEU and Fitfor55 Science-based Policy Recommendations for achieving the Energy Efficiency First Principle” the focus is on 2030 policy recommendations.
As a part of the roadmap, an investment strategy highlights which investments are necessary to be prioritized to achieve both short-term security of supply in 2030 and long-term decarbonisation goals in 2050.
