Renewable portfolio standards (RPS) are the most popular U.S. state-level policies for promoting deployment of renewable electricity (RES-E). While several econometric studies have estimated the effect of RPS on in-state RES-E deployment, results are contradictory. We reconcile these studies and...

In the last two decades, feed-in tariffs (FIT) and renewable portfolio standards (RPS) have emerged as two of the most popular policies for supporting renewable electricity (RES-E) generation in the developed world. A few studies have assessed their effectiveness, but most do not account for...

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....

In economic models of energy and climate policy, endogenous technological change is generally introduced as the result of either investment in research-and-development or of learningby-doing. In this paper, we analyze alternative ways of modeling learning-by-doing in the renewable energy sector...

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...

Deutschlands Stromversorgung steht an einem Wendepunkt. Kohle ist wie die Kernkraft keine Zukunftstechnologie. Auf den Zubau von Kohlekraftwerken kann verzichtet werden, wenn rasch in den Ausbau der erneuerbaren Energien investiert wird. Ein Weg in eine sichere und saubere Energieversorgung ist...

Die Verbraucherpreise für Strom sind in den letzten Jahren deutlich gestiegen. Dies ist zum Teil darauf zurückführen, dass die Umlage gemäß dem Erneuerbare-Energien- Gesetz (EEG) stark angestiegen ist. Derzeit macht die EEG-Umlage einschließlich anteiliger Mehrwertsteuer etwa ein Sechstel...
