Call for papers

We have received several requests to postpone the manuscript submission deadline, and decided to provide a FINAL extension to March 15, 2021. This will delay the Authors’ notification of Reviewers’ comments to May 15, 2021. This is the very last extension we are offering, because it will reduce to 15 days the time for Authors to then submit their final version on the website.
See you in Taormina!

The Organizing Committee


ECOS 2021, the 34th conference, will be held in Taormina, Sicily. The purpose of the conference is for participants to present new research results and exchange views on performance, economics, and environmental impact of energy systems, their design and possible advancements. Submission of applied and fundamental science papers are encouraged. We cordially welcome you to Taormina from all over the world. We expect that you will enjoy a fruitful week through the conference and the unequalled millenarian Sicilian culture.

Date and site
  • June 27 (Sun.) – July 2 (Fri.), 2021
