Freiburg is one of the four Regierungsbezirke of Baden-Württemberg, Germany, located in the south-west of the country. It covers the Black Forest (Schwarzwald) hills as well as the Rhine valley. It's sub-divided into the three regions (Regionalverband) Hochrhein-Bodensee, Schwarzwald-Baar-Heuberg and Südlicher Oberrhein.
Freiburg is a city of 205,000 people that was founded 900 years ago in the wine-growing area of southwest Germany, close to the French border, the upper Rhine and the Black Forest.
Freiburg's Central Station has installed a solar PV facade that is 19 floors tall, with 240 solar modules, and the city is full of houses whose owners have installed solar systems for electricity or hot water on their roofs.
Freiburg's goal is to decrease nuclear's influence, and increase the energy from renewables to 10% by 2010.
