Biofuels contribute to the mitigation of climate change. Directive 2003/30/EC thus aims at increasing the share of biofuels in total EU fuel consumption by up to 5.75 % by 2010. The rationale behind this directive can be found in potentially positive environmental impacts, most notably the...

Electricity generation based on renewable energy (RE) sources such as wind and solar replace the most expensive generators that often rely on fossil fuels. In response to RE promotion, wholesale electricity prices and carbon emissions are therefore expected to decrease. In interconnected...

This paper exploits the exogeneity of weather conditions to evaluate renewable energy (RE) subsidy programs in Germany and Spain in terms of their costs for reducing carbon dioxide emissions. We find that both the aggregate costs and the distribution of costs between energy producers and...

Energy firms provide key sources of energy needed to power the world economy. This paper offers a current overview of major energy firms in Germany, including location, geographic operations, and financial performance. German energy firms increasingly use renewable energy sources, thereby...

The diffusion of renewable electricity generating technologies is widely considered as crucial for establishing a sustainable energy system in the future. However, the required transition is unlikely to be achieved by market forces alone. For this reason, many countries implement various policy...

We develop a dispatch and investment model to study the role of power storage and other flexibility options in a greenfield setting with high shares of renewables. The model captures multiple system values of power storage related to arbitrage, dispatchable capacity, and reserves. In a baseline...
