The PROMITHEASnet in an attempt to enhance cooperation has invited its members to establish international research groups on Energy and Climate Change issues. These Groups will be formed by post doc scientists and researchers aiming to promote jointly research activities. The members of each group will work on common papers and submit their work apart from PROMITHEAS Journal to well known scientific journals with relevant topics. They will also send jointly written abstracts/papers and participate at workshops or conferences aiming to promote their work. As a parallel activity they can also submit proposals on open calls (FP7, Tempus, Intelligent Energy etc) for funding their research activities and examine possible means of finding for short time visits or exchanges of scientists in the near future.
