The environmental spokespersons of the Hegel-Gymnasium have been trained by an expert to become "solar scouts for balcony power plants" and issued the following challenge for the Hegel-Gymnasium in Stuttgart-Vaihingen on a day of action: By the end of July, parents, relatives and friends of the Hegel students* and teachers will install 30,000 watts through balcony power plants. https://www.hegelgymnasium.de/was-wir-tun/nachhaltigkeit/
So far (as of 27.3.24), 3540 watts have been installed. The environmental spokespersons of the Hegel-Gymnasium hope that many more balcony power plants will be installed on their initiative.
