Engineering for Change

Interest: Energy

When the sun goes down, the day ends. No work after dark, no studying. That’s the reality for one quarter of the world’s population that lives without electricity. Inventive design and the falling cost of solar power is lighting up homes that the traditional energy grid has left dark. Power solutions that can scale are filling in the grid gaps with solar, hydro, wind and biogas. With alternative energy solutions, the world is lighting up.
