A new program from Husk Power Systems, a Colorado-based company that installs off-grid power systems in the developing world, aims to dramatically expand renewable energy access in Nigeria. By installing at least 500 community “microgrids” by 2026, Husk hopes to improve livelihoods in a part of the world where energy access is still sparse.

Rooftop solar panels and battery storage are coming to three Minneapolis neighborhoods as part of a new effort to safeguard the city from power outages. Under the program from Xcel Energy, the area’s largest utility, so-called “resilience hubs” are expected to offer much-needed backup electricity in the event of a natural disaster.
