Integrated assessment models (IAMs) are a central tool for the quantitative analysis of climate change mitigation strategies. However, due to their global, cross-sectoral and centennial scope, IAMs cannot explicitly represent the temporal and spatial details required to properly analyze the key role of variable renewable electricity (VRE) for decarbonizing the power sector and enabling emission reductions ...
This paper applies Benders decomposition to two-stage stochastic problems for energy planning with multiple climatic years, a key problem for the design of renewable energy systems. First, we implement Benders decomposition with existing enhancements suited for the characteristics of the problem, a simple continuous masterproblem and fewbut large sub-problems. Next, we develop a novel trust-region ...
Ein Klimageld als sozialer Kompensationsmechanismus zur CO2-Bepreisung gehört zu den Kernprojekten der Ampel-Regierung, um die Akzeptanz der Marktsystems zu gewährleisten. Zuletzt wurde die Erhöhung der CO2-Bepreisung im Rahmen des dritten Entlastungspaket bis 2024 allerdings ausgesetzt. Eine repräsentative Befragung zeigt jetzt, dass rund drei Viertel der deutschen wahlberechtigten Personen mit Onlinezugang ...
As the COVID-19 pandemic progressed in the USA, ‘hotspots’ shifted geographically over time to suburban and rural counties showing a high prevalence of the disease. We analyse population-adjusted confirmed case rates based on daily US county-level variations in COVID-19 confirmed case counts during the first several months of the pandemic (1 March 2020 through 23 May 2020) to evaluate the spatial dependence ...
The German Federal Government passed the “Easter Package” in July 2022, which envisages a number of measures for the expansion of renewable energy sources. The package retains sliding market premiums as a remuneration mechanism, which protect electricity producers unilaterally, while contracts for difference (CfDs), which also protect electricity customers, are only used in the offshore wind sector. ...

Aufgrund der starken Abhängigkeit Deutschlands von russischem Gas müssen alle Möglichkeiten zum Gassparen genutzt werden, um eine mögliche Gasknappheit zu vermeiden. Zugleich sind die Gaspreise stark gestiegen und besonders betroffene Haushalte müssen entlastet werden. Auf Grundlage einer Auswertung des Sozio-oekonomischen Panels (SOEP) werden verschiedene Entlastungsoptionen verglichen und deren Vor- ...
