The ISUenergy 2026 will cover a wide spectrum, from the fundamentals of renewable energy technologies (photovoltaics, solar thermal energy, wind, hydropower, and geothermal) and their transmission and storage technologies (using solid, liquid, and gaseous concepts) as well as their development, component production, and industrialization up to the realization of sustainable energy systems and the political and economic framework conditions. This enables the development of a holistic view of the complex interrelationships involved in succeeding in the energy transition to a sustainable economy.

The schedule is composed of lectures in the mornings and hands-on labs with experiments and group work in the afternoons. In the breaks, groups and evenings, there is plenty of room for exchange and the discovery of exciting new research approaches or economic models. We also use a carefully selected and unique combination of presentations, interactive learning, practice, group work and self-training (Video ISUenergy 2026).

Participation is open to students from various disciplines, such as engineering and economics, including systems and electrical engineering, electronics, energy and environmental technology, mechanical engineering, architecture, as well as physics, chemistry, process engineering, computer science, business, renewable energies, and political science. The breadth of the program is suitable for bachelor's, master's, and doctoral students, as well as for interested professionals who want to expand their interdisciplinary skills.

As part of the course, we issue a final certificate of attendance and proof of attendance valued up to 4 ECTS credits, after the final exam and the group project presentation are successful. Therefore, continuous attendance in full-time during the course days is necessary.
