This study analyses time-dependent rhythms in happiness in three aspects. We show that the Sunday neurosis exists exclusively for men with a medium level of education and both men and women with high levels of education. Men with high levels of education may even experience a weekend neurosis....

We examine the effects of future renewable expansion in Germany on residual load and renewable surplus generation for policy-relevant scenarios for 2022, 2032 and 2050. We also determine the storage capacities required for taking up renewable surpluses for varying levels of accepted curtailment....

Recent developments in electricity markets such as the increased deployment of variable renewable generation have prompted renewed interest over the role of energy storage. While storage technologies can in principle provide various benefits for the functioning of an electrical grid, many energy...

In order to achieve cost-effective RES-E deployment it is often argued that technology-neutral support schemes for renewables are indispensable. Against this background, RES-E support policies making widely use of technology differentiation in remuneration settings, e.g. across the EU, are...

Die Ampelkoalition steht vor der Herausforderung, ihre energiepolitischen Ziele zu erreichen. Will sie dabei nicht scheitern, muss sie das Tempo der Energiewende deutlich steigern. Anlässlich der aktuellen energiepolitischen Debatte wurde am DIW Berlin der sogenannte Ampel-Monitor Energiewende...

The so-called traffic light coalition is facing a challenge: it has set ambitious energy policy targets, but can only achieve them if the pace of the energy transition is increased significantly. To contribute to the current energy policy debate, the Ampel-Monitor Energiewende (Monitor of the...

After a period of hibernation, the development of pumped-hydro storage plants in Germany regains momentum. Motivated by an ever increasing share of intermittent renewable generation, a variety of energy players considers new projects, which could increase the available capacity by up to 60%...

Die Energiewende ist ein Paradigmenwandel, der Politik, Wirtschaft und Gesellschaft vor große Herausforderungen stellt, aber zugleich erhebliche Chancen offeriert. Kernenergie und fossile Energieträger sollen durch erneuerbare Energien ersetzt werden und die Energieeffizienz soll in einem bis...

Im Zuge der Energiewende werden die fluktuierenden erneuerbaren Energien in Deutschland stark ausgebaut. Dadurch ergeben sich neue Herausforderungen für das Elektrizitätssystem. In diesem Beitrag wird zunächst dargestellt, welche Arten von Speichern und anderen Flexibilitätsoptionen...

The German energy transition makes it necessary to increase flexibility in the electricity system. Different forms of power storage may play a part in this, yet there is competition with other options on the production or demand side. In the short term, the further expansion of electricity...
