Call for abstracts:

Thank you for submitting an abstract for the ISEC 2020 conference.

We are sorry to inform you that we have decided in the Organizing Committee of the International Sustainable Energy Conference 2020 (ISEC 2020) to postpone the conference by one year to 13 - 15 October 2021 due to the effects of the corona pandemic.

Although quite many abstracts were submitted as part of the Call for Abstracts, we felt that a postponement was necessary because a large part of the submissions by experts came from other EU countries but also a considerable number came from countries outside the EU. In addition, it is currently not possible to estimate whether and when the existing travel restrictions and the ban on events with several hundred participants will be lifted in the coming months.

Your submitted abstract will remain in the system and will be reviewed in 2021. Before the review, however, you have the possibility to update your abstract from 13th January until 14th March 2021. You will also get a reminder again in January 2021.

We hope to see you at ISEC 2021 in Graz, Austria.
