For Classes I to V, an art competition took place in January 2022 with prior theoretical introductions on sustainable energy. The competition motivated both the students and their families to think about generation of sustainable energy and its rational use, and how they could conserve energy in their everyday lives. The winning photographs were showcased in a colourful exhibition, which motivated the students further. The theoretical lectures included renewable energy, energy efficiency, energy conservation, climate change and environmental protection. They were conducted by international environment experts of the Independent Institute for Environmental Matters (UfU, Germany) and the Confederation of Indian Industries (CII, India). Based on the lectures, an online quiz was organised to anchor gained knowledge.
