This study analyzes the effects of the Renewable Energy Sources Act (EEG). Macroeconomic effects, as well as effects on individual companies, are considered. The analysis focuses on the electricity markets and reflects the interactions of the different environmental policies and their mutual impacts. Additionally, the study analyzes alternative support policies and develops suggestions for further improvement of the current legislation and framework conditions.
