The energy transition is driven by tangible, real-world projects – exactly the kind of solutions highlighted in the documentary “Good News from the Planet – How can we use the sun intelligently?” by ARTE.
The 44-minute report presents innovative approaches to solar energy use around the world. A particular focus is placed on the intelligent use of existing infrastructure.
Practical example: Foldable solar roof at the Schweinfurt wastewater treatment plant
From minute 25:55, the documentary features dhp Technology’s foldable solar roof installed at the Schweinfurt wastewater treatment plant.
The project demonstrates how existing infrastructure can be efficiently used for energy generation:
The foldable solar roof is installed above the treatment basins, generating renewable electricity without requiring additional land or interfering with plant operations.
At the same time, the structure protects the basins below from weather conditions, contributing to more stable operational processes.
Dual use – double benefit
This project exemplifies a key principle of the energy transition:
Combining energy generation with existing infrastructure.
Wastewater treatment plants, in particular, are energy-intensive facilities with significant on-site electricity demand. By integrating photovoltaic solutions directly on-site, part of this demand can be sustainably covered.
The foldable solar roof enables flexible, site-adapted deployment – especially in regions with challenging weather conditions.
A scalable solution for infrastructure areas
Beyond wastewater treatment plants, the concept also offers significant potential for other applications, such as parking areas or industrial sites.
The documentary clearly shows:
Innovative technologies like the foldable solar roof contribute meaningfully to the energy transition – not only as individual projects, but as scalable solutions for existing infrastructure.
