The study examines options for a medium-term and long-term attainment of German goals for the reduction of greenhouse gases by 2050. The focus lies on finding cost-optimal development pathes in the energy consumption sectors of buildings, transportation, industry and in the energy sector. The study finds that a technology-open approach is to be preferred to an extensive electrification of the consumption sectors. In addition, the German climate goals are classified into the European context, incentive structures are analyzed from stakeholders’ pespectives, and recommendations for a further development of legal frame conditions are yielded. The study was commissioned by the Ministry of Economy, Innovation, Digitalization and Energy of the state of North Rhine-Westphalia (MWIDE). The ef.Ruhr GmbH is the cooperation partner for examining the implications on the electricity networks.
