Welcome from the Chair
Dear Colleagues,
We are excited to announce the 3rd International Online Conference on Energies (IOCEN 2026), which will be held virtually from 12 to 15 May 2026.
This conference will showcase the latest research and advancements in energy resource management, focusing on areas such as energy sources, energy conversion, energy policy, energy fundamentals, smart energy, and other energy innovations, with an eye open towards sustainable use of resources. We aim to explore the current landscape, address existing challenges, and identify opportunities.
We warmly invite all energy researchers, professionals, and innovators to participate and share their expertise in the following thematic areas and related topics:
S1. Energy Sources (Fossil & Renewable);
S2. Energy Conversion (Heat and Mass Transfer, Combustion, Thermodynamics, Entropy & Exergy Analysis);
S3. Energy and Environment. Sustainable Transition;
S4. Smart Cities and Urban Management;
S5. Advanced Energy Materials;
S6. Electrical Power Systems;
S7. Energy Economics and Policy (Thermo-Economics, Exergy Economics);
S8. AI Applications to Energy Conversion Systems.
The conference committee will review the submitted abstracts. All accepted abstracts will be available online in open access format on Sciforum.net during and after the conference. Following the conference, selected contributions will be invited for submission to the Energies journal (ISSN 1996-1073, Impact Factor: 3.2), with a 20% discount on the publication fee.
We look forward to your participation in this inspiring event.

Dr. Enrico Sciubba (M.Eng. Roma 1972, Ph.D. Rutgers, NJ 1981) is Professor of Turbomachinery & Energy Systems in the Dept. of Mechanical & Industrial Engineering of the Niccolò Cusano University of Roma. From 1986 through 2019 he held the same position at the University of Roma Sapienza. He has held industrial positions in Germany (1973-75) and Italy (1975-78) and taught in the field of Thermal Sciences at Rutgers University (1980) and Catholic U. of America (1981-85). He was a Fulbright scholar (1978-1981), and holds two honorary Doctoral Degrees, from the U. of Galati and from Ovidius University (Romania). His currently active research topics are the exergy analysis of complex systems, from single processes to industrial Sectors to entire Societies; the study of the links between Thermodynamics and Sustainability; the CFD-aided optimization of energy-conversion components; the design and prototyping of ultra-micro gas-turbines for hybrid vehicles and as portable power generators. He has authored or co-authored 4 books (2 in english) and over 200 scientific papers. Professor Sciubba is an ASME Fellow, a member of several international Engineering Societies. He is the General Secretary of the ECOS International Society, a community dedicated to the improvement of the efficient and sustainable resource-to-final use conversion. He is the Editor-in-Chief of the Journal Energies (https://www.mdpi.com/journal/energies), and Associate Editor for Energy, Int. J. of Thermodynamics, Int. J. of Energy Research and J. Energy Resource Technology.
