The Energy Challenge Badge is designed to show the crucial role energy plays for life on our planet as well as for our daily lives. It looks at the different sources of energy, considers how people use energy and how our planet is affected by it, and motivates young people to save energy and use clean energy.The YUNGA Learning and Action Series - Challenge Badges, developed in collaboration with other United Nations agencies, consists of short books that aim to raise awareness among youth on topical issues and to encourage them to become active agents of change in their local communities.
