Ulm is a city in the federal German state of Baden-Württemberg, situated on the River Danube. The city, whose population is estimated at almost 120,000 (2015), forms an urban district of its own (German: Stadtkreis) and is the administrative seat of the Alb-Donau district. Founded around 850, Ulm is rich in history and traditions as a former free imperial city (German: freie Reichsstadt). Today, it is an economic centre due to its varied industries, and it is the seat of the University of Ulm. Internationally, Ulm is primarily known for having the church with the tallest steeple in the world (161.53 m or 529.95 ft), the Gothic minster (Ulm Minster, German: Ulmer Münster), and as the birthplace of Albert Einstein.
In 2007 the City of Ulm was awarded the European Energy Award for its remarkable local energy management and its efforts to combat climate change. Examples of these efforts are a biomass power plant operated by the Fernwärme Ulm GmbH (10 MW electrical output), and the world’s biggest passive house office building, the so-called Energon, located in the “Science City” near the university campus. Moreover, the city of Ulm boasts the second largest solar power production in Germany. For all new buildings, a strict energy standard (German KFW40 standard) has been mandatory since April 2008. Ulm Minster has been fully powered by renewables since January 2008. Until the end of 2011 as a European pilot project a self-sustaining data-centre will be constructed in the west-city of Ulm. There is a solar-powered ferry that crosses the Danube 7 days a week in summer. The “Bündnis 100% Erneuerbare Energien” was founded in February 2010 with the aim of bringing together the people and organisations seeking to promote the transition to 100% renewable energy in Ulm and Neu-Ulm by 2030.
