The 1% of Vietnamese households without electricity rely on decentralized, micro renewable systems for power supply. Are such innovations sustainable?

LAI CHAU, VIETNAM – In November 2019, teachers and students at the Pa U elementary boarding school in Muong Te district in Vietnam’s Lai Chau province had electricity for the first time.
The power came from a rudimentary micro wind turbine system, which was sold and delivered to the school by a local startup named 1516 and assembled by the teachers.
The setup was simple: aluminum tubs affixed to a sturdy wooden rod, linked to a sun box that contains a charge controller, a solar battery and an inverter to generate electricity.

“The children were so excited to see those turbines in action,” recalled teacher Bui Thi Minh Khuyen. Despite a limited output that can only sustain the school’s energy needs until 10pm, the new power supply has made a vast difference.

Previously, the school only had light bulbs powered by cheap solar panels imported from China. Fans, radios, TVs, phones and laptops were luxuries the school could not power.
