American Samoa Power Authority

A small island in American Samoa is making the switch from diesel generators to 100 percent renewable energy. Ta'u, the easternmost of the Samoan islands, has just been equipped with a new microgrid, with 1.4 megawatts of solar generation capacity and 6 megawatt-hours of battery storage. It's enough to power the entire island -- both night and day.
