With over 100,000 square meters of pavilions, outdoor areas, and parking spaces to showcase the energy transformation already underway, the event allows visitors to hear firsthand from its protagonists about the various sectors where new ideas for change are being implemented: businesses, institutions, organizations, utilities, startups, institutions, and citizens. It’s a moment of discussion and exchange, where we can plan, but above all, create, something new. Sustainable energy concerns everyone.

The future is entrusted to the new generations. The HEYSUN Schools Project is aimed at students and teaching staff with the aim of promoting structured training and teaching programs on sustainability issues. The project involves the creation of dedicated spaces and educational activities designed to encourage active participation among participants, enhancing the role of schools as places of learning, discussion, and growth. Through an integrated educational approach, the initiative aims to support the acquisition of knowledge and skills useful for disseminating best sustainability practices applied to everyday life, contributing to the formation of informed and responsible citizens.

In addition to showcasing new energy system components, equipment, and prototypes, HEYSUN 2025 will also feature a rich program of cultural, educational, and informational initiatives related to sustainability and the energy transition: round tables open to all participants, conferences and seminars with distinguished figures, scientists, and researchers in the energy and environmental sectors, specialized workshops, and opportunities for discussion with representatives of exhibiting companies to bring ideas and projects to life, and much more.

The symbol of renewable energy is the Sun, but at the HEYSUN 2025 event there will be space for every aspect of the energy transition and for all the players that represent it: from high-concentration solar thermal and thermodynamic energy to photovoltaics, from wind power to geothermal and hydroelectric energy, but also to the new model for sustainable hybrid/electric mobility, with special attention to high-efficiency cogeneration plants, smart and sustainable cities, Renewable Energy Communities and much more.
