"Students, please imagine what it feels like to be at an altitude of 4,500 meters on a plateau without electricity. How can we have environmental-friendly and convenient electricity?" a teacher asked in the classroom.

Centering on the topic of foldable mobile light storage integrated equipment on “Yak's Back," the volunteers showcased how it serves the electricity needs of nomadic communities in Xizang, which immediately triggered the students' interest. From the principles of new energy generation such as solar and wind power to discussions on available clean energy sources, students engaged in discussions guided by the volunteers. Students from the Second Middle School of Biru county joined the exchange through the online classroom where they provided energy-saving tips and pledged to be environmental pioneers.
