Dardesheim, Germany


100% Renewable Energy Goal Achieved:

4000% renewable electricity

100% Renewable Energy Goal:

100% renewable energy target for transportation, heating/cooling.



Dardesheim in the Harz Mountains of Germany has a population of 1000 people, and by 2009, produced ten times more energy for electricity, heating and transport than its inhabitants consume - and some 40 times more electricity than local demand. Half of local household electricity demand is provided by 19 large photovoltaic rooftop systems. In addition Dardesheim features the world's largest wind turbine: a 6 megawatt, 125 meter giant. The municipality also operates some RE powered electric cars, and local garages offer fuel modifications for vehicles from diesel fuel to vegetable oil."


Q & A With  Heinrich Bartelt, RegenerativKraftwerke Harz GmbH & Co. KG


1. What inspired the decision for your community to pursue your 100% renewable energy goal?  

The city council decided in 2006 to become a “Renewable Energy Town”  after 15 years of activities supporting and shifting towards renewable energy (Added by Go 100 Percent: The town’s first 80 kW windmill was installed  in 1993.)  

2. What mix of technologies have you used and/or do you intend to use? Why have you made these choices?  

Wind power, solar PV and biomass produce 40 times more electricity than Dardesheim needs, and 10 times the need for electricity heat, cooling and mobility. 

3. What have been the greatest obstacles so far? If you have overcome any of them, how did you do it?  

The biggest challenge besides reaching the 100% renewable energy goal was to get a 100% support from our community.  We managed this by offering different forms of community participation in the projects.    

4. Were there policies that were particularly effective to helping your project advance?
Were there any policies or regulations that stood in your way, and if so, how have you handled this?

The most important framework is the EEG (Feed-in-tariff) with a 100% interconnection guarantee, a must-take provision, and a minimum compensation for all renewable sources which feed into the grid.    

5. What have been the greatest benefits of your project so far?  

Clean environment, added value in the region, jobs, promotion with the help of local associations of social and cultural local activities, increasing energy security and reducing international conflicts over scarce fossil resources, and participating with joy.
