The paper first outlines the challenges the global energy system is facing. It then summarises the present knowledge of energy efficient solutions in all energy using sectors from primary energy to useful energy and, more importantly, from useful energy to energy services (material efficiency...

Seit Mitte des 20. Jahrhunderts verändert sich das Erd- und Klimasystem dramatisch. Die weltweite Durchschnittstemperatur steigt und führt zur Zunahme von Extremwetterlagen und zum Rückgang der Artenvielfalt. Die Hauptursache dafür ist der durch den Menschen verursachte Anstieg der...

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...

Germany has committed itself to reducing its carbon emissions by 25 percent in 2005 as compared to 1990 emission levels. To achieve this goal, the government has recently launched an environmental tax reform which entails a continuous increase in energy taxes in conjunction with a...

Germany is struggling to meet its 2020 greenhouse gas (GHG) emission and climate goals. Against this background, we analyze the current draft National Energy and Climate Plan (NECP) that sets out how Germany aims to achieve its national and European climate goals by 2030. We introduce the...

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...

We develop a model of optimal carbon taxation and redistribution taking into account horizontal equity concerns by considering heterogeneous energy efficiencies. By deriving first- and second-best rules for policy instruments including carbon taxes, transfers and energy subsidies, we then...

The success of climate policies depends crucially on the dynamics of public support. Using unique longitudinal data from three surveys conducted between 2019 and 2022, we study the variations of public support for carbon pricing in Germany. The period includes two relevant events: the...
