The reduction of greenhouse gas (GHG) emissions, in particular CO2, is a major objective of the German energiewende. There has been broad consensus on this goal for many years now - in contrast to the continuing discussion over the proposed shutdown of Germany’s nuclear power plants. The...

The European Green Deal, initiated by the EU Commission, is a package of measures aimed at decarbonization and sustainable economic development with the goal of making the European Union climate neutral by 2050. To achieve this goal, the emission reductions target must be increased from 40...

Amidst other national and global climate protection initiatives, the new EU Commission under the leadership of Ursula von der Leyen is facing the challenge of concretely following through on previous announcements regarding an ambitious climate policy. Specifically, action must be taken to raise...

The aim of this paper is to showcase different decarbonization pathways for Germany and Europe with varying Carbon dioxide (CO2) constraints until 2050. The Global Energy System Model (GENeSYS-MOD) framework, a linear mathematical optimization model, is used to compute low-carbon scenarios for...

The European Union has embarked on the transformation of its energy and electricity system to low-carbon energy sources, just like Germany and many other countries. This chapter analyzes the European strategy for low-carbon transformation in relation to specific aspects and features of the...

Both in the German energiewende and in the European low-carbon energy system transformation, infrastructure is generally considered as a conditio sine qua non: a necessary though not sufficient condition for a low-carbon economy - and one without which energy transformation may fail. At second...

Long-term scenarios of the low-carbon energy transformation in Europe are quite diverse. In this chapter, we provide a detailed discussion of scenarios leading to a far-reaching decarbonization of the European energy system to 2050. We use an updated version of the Global Energy System Model...

The energiewende "made in Germany" is a relatively recent phenomenon, yet with a long germination period, going back to the 1970s, and it has attracted broad interest in many spheres, including academia, industry, and policy making. The previous chapters have provided insights into specific...
