Due to ambitious climate change targets and other energy and industrial policy goals such as the nuclear phase-out, the energy transition in Germany is heading toward a completely renewable energy system. This Weekly Report is the first to describe scenarios for 100 percent renewable energy...

The German response to the Fukushima nuclear power plant incident was possibly the most significant change of policy towards nuclear power outside Japan, leading to a sudden and very significant shift in the underlying power generation structure in Germany. This provides a very useful natural...

This paper exploits the exogeneity of weather conditions to evaluate renewable energy (RE) subsidy programs in Germany and Spain in terms of their costs for reducing carbon dioxide emissions. We find that both the aggregate costs and the distribution of costs between energy producers and...

While progress in reducing greenhouse gas emissions is notable in the power sector, other sectors such as transportation and often heating are lagging behind. A strategy to propagate greenhouse gas emission reductions from the power sector to other sectors is so-called "sector coupling." Against...

Exploring pathways for transitioning to clean energy to achieve climate change mitigation goals is essential. Addressing the economic impact of decarbonization options requires strategic planning to determine cost-effective CO2 mitigation strategies. The assessment of marginal CO2 abatement cost...

The harmonization and integration of separate national energy markets to an interconnected internal European market is a top priority of the European Commission. However, as energy policy largely remains subject to national sovereignty, a higher degree of integration can cause unilateral...

The reliability of the electricity grid is of vital significance for the proper functioning of a society and its economy. The aim of this study is to develop a methodology to quantify differences in the electricity distribution grid's economic importance, and investigate limitations for its...

The option of adapting to climate change is becoming more important in climate change policy. Hence, responding to climate change now involves both mitigation to address the cause and adaptation as a response to already ongoing or expected changes. These changes are also of relevance for the...

Zu Beginn des Jahres 2005 startete das europäische Emissionshandelssystem. Die vorliegende Studie beschäftigt sich mit den Auswirkungen des Emissionshandelssystems auf die deutsche Energiewirtschaft. Dargestellt und analysiert wird zunächst die europäische Emissionshandelsrichtlinie...
