This small-group activity uses engineering concepts to design energy systems for three off-the-grid towns in Mali, Ethiopia, and Namibia.

This short video shows how humanity uses energy today; what sources we use; and why, in the future, a growing global population will require more energy.

In this activity, students learn about the energy sources used by their local utility provider to generate electricity, and work in small groups to evaluate the sustainability of either a renewable or non-renewable energy source used to generate electricity.
