The work gives an overview about the current situation of renewable energy sources in South Tyrol, the northern province of Italy. In the main part the potentials of renewable energy sources until 2050 are analysed in order to evaluate the possibility of reaching "Energy Autarky" including transportation. The methodology used is a literature and information research about the current data of renewable energy sources in South Tyrol. The evaluation of the potentials for renewable, local energy production in the future was conducted by the use of literature, information research in the internet, personal interviews with responsible people in the field of renewable energy, with local energy experts and by own analysis, elaborations and calculations. The obtained information is presented in the main part. The most important conclusion from the potential analysis is that in South Tyrol a 100% renewable "Energy Autarky" is not possible until 2050. The ratio between local energy consumption and local renewable energy production (ESS) will rise until 2015 from 64% to 69%, until 2020 to 91% and until 2050 to 96%. The calculation includes electricity, heat and mobility sector as well as energy efficiency and energy savings in residential buildings and private households. The results obtained provide a comprehensive input for future policy formulation and implementation.
