The Stadtwerke Ice Festival is not only attracting enthusiastic visitors again this year, but is also stepping up its efforts to save energy. Compared to the 2019/2020 ice season, impressive savings of at least 20% are to be achieved. This will be achieved through the use of state-of-the-art cooling technology and the use of multi-year plastic rinks for curling. The use of 100% green electricity makes the event environmentally friendly. The Stadtwerke Ice Festival can thus not only spread fun and enjoyment, but also shows that sustainable events are possible and energy savings can also be implemented at large events.
