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...

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 the first phase of the energiewende, focusing on the electricity sector, was largely successful, the second phase needs to focus on all energy usage, especially heat, transportation, and usage as a raw material in the chemical industry. In that context, intensified "sector coupling" will...

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...

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...

Die Ampel-Koalition hatte sich vorgenommen, die Energiewende deutlich zu beschleunigen. Auf Basis der Daten des Ampel-Monitors Energiewende des DIW Berlin werden in diesem Bericht die Entwicklungen wichtiger Schlüsseltechnologien analysiert und eine Bilanz der Energiewendepolitik gezogen. Die...

Energy system modeling supports the identification of the optimal technology mix to achieve decarbonization targets across multiple sectors. Especially when sector coupling is considered for future technology landscapes, the large solution space leads to a complex optimization problem in terms...
