The energy master plan of Ludwigsburg, Germany comprises strategic targets and projects across electricity, heating, transport, and renewable energies. It aims to optimize energy use in city planning and buildings through sustainable concepts and decentralized, independent energy supply. The plan was developed in collaboration with local partners and citizens, and identifies over 200 GWh of potential renewable heating sources. It recommends 25 priority measures across communication, infrastructure, and renewable programs that could reduce CO2 emissions by 2 tons per capita by 2050 according to climate targets. Examples include energy-efficient housing developments using central and decentralized renewable heating.

7. Thematic area: Energy Strategic targets lighthouse projects energetic optimization of city planning and buildings Sustainable energy concept Independent and decentralized energy supply Intensive public relations and consultation offers Support of renewable and regional energy types Energy saving in transport

8. The Ludwigsburg energy master plan Comprises the areas of electricity, heating, transport, cross-cuting measuers and renewable energies was supported by 80% through the framework of the „National climate protection initiative“ from the Federal Ministry for the Environment was developed in cooperation with the University of Stuttgart, the Ludwigsburg Energy agency and the public utility company Ludwigsburg-Kornwestheim

9. Time schedule October 2008/ February 2009 Application/Confirmation of support from the Ministry until end of 2009 Inventory and analysis of potential, after that development of guidelines and measures May / July 2010 Round table and future conference for the topic energy after that Completing list of measures, overall report, recommendations for reduction targets and scenarios, 25 recommendations for actions 26.01.2011 16.03.2011 Workshop in the town council Decision on reduction targets and priorities

13. Public participation Regular monitoring through experts such as representatives of Ludwigsburg energy agency, Energetikom, the municipal utility company and city administration Round table on 18.05.2010 with over 50 experts from economy and stakeholders from Ludwigsburg: discussion, further development and assessment of measures in the areas of electricity, heating, transport, renewable energies and comprehensive measures „ Future conference Energy“ on 9./10.07.2010 with 80 citizens about the results, development of implementation possibilities

14. Recommended procedures Recommended procedures from IER includes 25 measures from different areas, which have been chosen because of the relation CO ² reduction/costs, CO ² saving potential and contribution to regional value creation With this the CO ² emissions can be decreased by 2t/capita until 2050 (prerequisites IPCC for „climate neutrality“) Priorities were set for the coming three years, those were decided by the town council in March. After concretising content and costs the council will decide about concrete implementation.
