"History teaches us that men and nations behave wisely once they have exhausted all other alternatives"

Abba Eban
"You never change things by fighting the existing reality. To change something, build a new model that makes the existing model obsolete."

Buckminster Fuller, philosopher, futurist and global thinker (1895 - 1983)
"If there are to be problems, may they come during my life-time so that I can resolve them and give my children the chance of a good life."

Kenyan proverb


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

Excepcionally, in case of presenting conference papers that were submitted in Portuguese or Spanish, oral presentation can also be in the language of submission.

There will be no simultaneous translation provided, so participants presenting in Portuguese or Spanish will not have privilege of being listened to, and discussed with international researchers, which will hugely decrease the visibility of their work.


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.

AV Equipment

Other information
