"Then I say the Earth belongs to each generation during its course, fully and in its right no generation can contract debts greater than may be paid during the course of its existence"

Thomas Jefferson, September 6, 1789
"Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs."

The Report of the U.N. Brundtland Commission, Our Common Future, 1987
"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)


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

Oral presentations will be supplied with the following equipment: PC computer, Data projector, Screen of appropriate size, Microphone and Loudspeakers in bigger halls, and Laser pointer. Personal notebook can be used only in the case when it is equipped with VGA HD15pin female output.

Other information

The conference organizers do not provide the templates for preparing the presentations. The authors are free to use their own templates and are entirely responsible for the presentation content (order, the loading, graphics...etc.). If it is necessary, presenters will have the opportunity to check their presentations in the appropriate session room during breaks. In this case please consult the registration desk staff for further instructions.
