Presentation guidelines


How the hybrid conference works?

The conference will be held as a hybrid one. All authors (both the ones who registered for online participation and ones who opted for on-site) will be required to prepare a pre-recorded video presentation that will be available on our online conference platform (instructions will be available soon). The platform will be available through the entire duration of the conference as a video-on-demand service for all participants. Participants can submit questions through the platform and authors will be required to respond before the end of the conference. There will be no specific time for the presentation so participants can view presentation at their own pace.

Participants who will be present in Dubrovnik will have a separate (on-site) schedule compiled only from submissions by on-site attending participants. The schedule will be announced after the final registration deadline.


Oral presentations must be prepared and exposed in English. Presenters should be sufficiently fluent in English to run presentation and discussion on high academic standards.


Only electronic files will be accepted for oral presentations. The authors should provide the presentations in either Microsoft PowerPoint format (*.ppt, *.pptx) or Adobe PDF format. Presentations created in MAC format have to be converted in to PC format (if authors plain to use the SDEWES PC Computers for presentation) and checked in advance to their Windows compatibility.


Authors should provide a copy (preferably on a USB memory stick or USB memory drive) to the Conference Technical Staff in the corresponding meeting room at least 15 minutes before the session start. If it is necessary, presenters will have the opportunity to check their presentations during the break before session starts.


Date, time and session room for oral presentations is displayed in the Conference schedule. Presenters are asked to meet the chairman of each session at the beginning of the break before session.


The time slot for each presentation is 20 minutes for regular and keynote presentations, and 45 minutes for invited plenary lectures. This duration include time for questions and answers: 5 minutes for regular and keynote presentations, 15 minutes for invited plenary lectures. Session chairs will hold presentations strictly to the allotted time.
