The new exhibition focuses on hydroelectric power – its history and technology.

Since when has water been used to produce electricity? How does a turbine work? Are hydroelectric power and environmental protection compatible?

We address these questions through various installations. Visitors can also find out how ewz is contributing to the city’s net-zero target and what energy-saving options are available.
