Book excerpt: The purpose of the United Nations Challenge Badges is to raise awareness, educate and, most of all, motivate young people to change their behaviour and be active agents of change in their local communities. Challenge Badges are appropriate for use with school classes and youth groups, and are endorsed by WAGGGS and WOSM. They include a wide range of activities and ideas that can easily be adapted by teachers or leaders. Additional badges are available or are being developed on a number of other topics, including: Agriculture, Biodiversity, Climate Change, Forests, Gender, Governance, Hunger, Nutrition, the Ocean, Soils and Water. 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. The badge 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 to engage in efforts to increase access to clean energy.
