The European Union has set the ambitious long-term climate and energy goal to reduce the amount of emitted greenhouse gases by 80-95% until 2050. In 2015 the United Nations Climate Change Conference in Paris reached an agreement to hold the increase in global temperature well below 2C and even try to limit the increase to 1.5C. Thus measures on both a European and National levels have to be set in order to achieve these goals. Austria agreed on an 'Energy Strategy' in 2010, in which - besides the reduction of energy use, an increase in energy efficiency, and the implementation of a sustainable infrastructure - the expansion of renewable energies is focused on as a key element of the strategy. Spatial planning has an important role in the task of securing the required areas for this expansion as well as promoting the expansion of renewable energies, as also stated in the Austrian Spatial Development Concept (ÖREK 2011).The present study examines the provisions on the topic of renewable energy in the planning law of the Austrian federal states, regarding prioritization of energy sources and the designated sovereign (spatial) level of these regulations. To achieve this objective, the renewable energies used in Austria are assessed in terms of the technical framework conditions, their use in the federal states, spatial requirements and environmental impacts and also their spatial relevance. Based on an analysis of previous studies, projects and strategies, additional requirements regarding spatial planning are then determined, and in a further step used to evaluate the previously examined provision. The result shows that, even though there is heterogeneity in regulations across federal states, there are not that many provisions at all.
