Unable to afford school fees, William Kamkwamba, 14, dropped out of secondary school in Malawi and taught himself to make a windmill from scratch.

His invention generated more than just electricity for his village (which never had power), but also lots of attention - from the media and the social sector.

Why? Not only does he show how innovative young people can be, he also offers hope that Africa can power itself with clean renewable energy.

Watch William’s remarkable story in this short documentary (below) that premiered on Pangea Day.
