The 6th AIGE/IIETA International Conference and 15th AIGE 2021 Conference on "Energy Conversion, Management, Recovery, Saving, Storage and Renewable Systems" is organized under the joint auspices of the AIGE and IIETA with the aim of providing technical information to their members and to the scientific and industrial community at large.
Traditionally the joint Conferences will give the opportunity to discuss the state of the art and to present experimental, analytical and numerical results in Energy Conversion Systems, in Energy Management, in Energy Recovery Systems, in Energy Saving Techniques, Energy Storage Systems and Renewable Systems, with a particular attention to the engineering, environmental and economic aspects.
After unprecedented COVID-19 pandemic the Conference Organizing Commitee has been felt the need to introduce a new conference topic regarding the impact of virus diffusion in the energy context. In our intentions this section is focused in the study of virus diffusion mechanisms,  new design and management methodologies for energy systems with the aim to mitigate virus transmission and  to the economic aspects related to the previous issues.
The following list of topics indicate topics that fall within the aim of the conference.
