In the recent discussion about the transformation of the energy system as well as the upcoming increase of the EEG-apportionment, the German government proposed to limit support for wind energy and biomass generation similar to the cap imposed on the photovoltaic sector. In contrast, the federal states have ambitious plans for the expansion of wind energy. Beyond the questions of a planned coordination as well as a network expansion associated with the transformation of the energy system, the study by the Institute for Ecological Economy Research (IÖW) on behalf of Greenpeace Deutschland pursues the question of the different economic implications with regard to the expected employment and value added effects by renewable energies. For this, the effects of the two relevant scenarios in the year 2020 were determined. First, Scenario C in the scenario framework for the NEP 2013 according to the expansion targets of the federal states. Second, the Scenario 2011 A in the long-term scenarios 2011 published by the German Ministry for the Environment, Nature Conservation and Nuclear Safety, which approximately meets the expansion target aspired by the German government. The difference between these two scenarios is mainly due to the varying increase in installed wind energy capacity. The results of the study show that the expansion of onshore wind energy, according to the targets set by the states, can generate significant effects of value added and employment in Germany. The study received a broad media response in the run-up to the energy summit on November 2nd, 2012.
