Photovoltaic (PV) technologies have demonstrated significant price reductions, but large-scale global application of PV requires further technology improvements and cost reductions along the value chain. We survey policies in Germany and China and the industrial actors they can encourage to pursue innovation, including deployment support, investment support for manufacturing plants and R&D support ...
Der Wärmemarkt spielt eine zentrale Rolle für die Erreichung der energie- und klimapolitischen Ziele der Bundesregierung. Insbesondere bei der Raumwärme in Wohngebäuden müssen große Einsparerfolge erzielt werden, wenn bis 2050 ein weitgehend klimaneutraler Gebäudebestand erreicht werden soll. Vor diesem Hintergrund hat das DIW Berlin gemeinsam mit der ista Deutschland GmbH eine aktuelle Datengrundlage ...
Adequate extension of electricity transmission networks is required for integrating fluctuating renewable energy sources, such as wind power, into electricity systems. We study the performance of different regulatory approaches for network expansion in the context of realistic demand patterns and fluctuating wind power. In particular, we are interested in the relative performance of a combined merchant-regulatory ...
This paper analyzes the trade-offs for using feed-in tariffs or tenders to remunerate different scales of solar photovoltaics (PV) projects. In recent years, European countries increasingly combined feed-in tariffs for small renewables systems with tenders for large installations. This study develops an analytic framework to quantify deployment effectiveness of responsive feed-in tariff adjustment ...
In northern Europe wind energy has become a dominating renewable energy source due to natural conditions and national support schemes. However, the uncertainty about wind generation affects existing network infrastructure and power production planning of generators and cannot not be fully diminished by wind forecasts. In this paper we develop a stochastic electricity market model to analyze the impact ...
This paper takes a financial market perspective in examining the relationship between oil prices, the US dollar and asset prices, and it exploits the heteroskedasticity for the identification of causality in a multifactor model. It finds a bidirectional causality between the US dollar and oil prices since the early 2000s. Moreover, both oil prices and the US dollar are significantly affected by changes ...
Auch im zweiten Jahr nach dem Kernkraftwerksmoratorium vom März 2011 bleibt die Lage im deutschen Stromübertragungsnetz stabil. Auch wenn die Realisierung einiger Ausbauprojekte um einige Jahre hinter dem ursprünglichen Zeitplan liegt, schreitet der Netzumbau kontinuierlich voran. Bei einigen kritischen Leitungen wurden im vergangenen Jahr erhebliche Fortschritte gemacht, unter anderem bei Verbindungen ...
