The Demo day on “Conservation Efficiency” was organised by the ONGC Officials to promote awareness and encourage students to contribute towards a cleaner environment through green and clean energy. The celebration featured a poster drawing and quiz competition on the topic "Cleaner Environment through Green and Clean Energy." The events aimed to inspire creativity, foster teamwork, and educate participants about the importance of sustainable practices. The experts from ONGC explained through demos and presentations about the topic to the students. Students from various departments of the college participated enthusiastically in the events, showcasing their artistic talents and knowledge on the topic. Prizes were awarded to the winners of the poster drawing and quiz competition, recognizing their outstanding efforts and creativity. The demo day achieved its objective of promoting environmental awareness and encouraging students to adopt sustainable practices. The events provided a platform for students to showcase their talents, learn from each other, and develop a sense of responsibility towards the environment. It fostered a sense of team spirit and environmental responsibility among students. We look forward to continuing such initiatives in the future. Future celebrations can include more diverse events, such as workshops, seminars, and community outreach programs, to further promote environmental awareness and sustainability.
