Experts in Team work is mandatory, but there are more than 80 possible topics (so-called Villages), and SESAM students can choose freely as long as their total course program will meet all requirements.
Any villages thematically strongly connected to Energy can be approved as part of the 80 ECTS SESAM specialization. See the Excel file for course selection for examples of approved villages.
Village Renewable Energy Management is led by Ruud and approved for SESAM specialization.
See specific Wiki item on Experts in Team work for more details.
