Einen Kern der Energiewende bildet der Ausbau Erneuerbarer Energien in Deutschland. Be-sonders im Strombereich greifen dabei EU-, Bundes-, Landes- und Kommunalpolitik sowie bürgerschaftliches Engagement eng ineinander, allerdings nicht immer reibungslos. Ziel dieser Studie ist es, bestimmte...

Unter heutigen Rahmenbedingungen muss davon ausgegangen werden, dass der globale Primärenergieverbrauch sich bis 2050 mehr als verdoppeln wird und die energiebedingten CO2-Emissionen sogar um 137% steigen. Die Abhängigkeit der OECD-Staaten von Energieimporten würde weiter wachsen und der...

China and India will have to radically transform their electric power systems in order to decouple economic growth from unsustainable resource consumption. While the majority of transition literature has focused on the diverse socio-technical factors that could enable such a transformation, more...

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...

Empirical studies on the link between green investment and other business investment at the firm level either focus on innovation specific types of investment or fail to consider the simultaneity of investment decisions. The analysis to be presented here offers a broad focus on different types...

Germany changed renewable remuneration for wind power from a fixed Feed-In Tariff (FIT) to a floating Market Premium Scheme (MPS) in 2012. One aim of this adjustment was to better align the supply of generated wind electricity with the demand for it, e.g. through more system-friendly wind...

We examine how different renewable energy support policies affect innovation in solar and wind power technologies. The analysis is conducted using policy and patent data for a large sample of 194 countries and territories. The policy data allows distinguishing two dimensions of regulation, i.e....

The costs of renewable energy technologies have fallen sharply. Now the financing costs of new installations are playing an increasing role in the overall cost of Germany’s energy transition. This has put the primary focus of support instruments for renewable energy on creating more affordable...

This working paper undertakes econometric analysis to assess the impacts of climate mitigation policies and the quality of the investment environment on investment and innovation in renewable power in OECD and G20 countries. It also assesses how countries’ investment environments interact with...

Power systems with increasing shares of wind and solar power generation have higher capital and lower operational costs than traditional technologies. This increases the importance of the cost of finance for total system cost. We quantify how renewable policy design can influence cost of finance...
