TED: Meet mini-grids — the clean energy solution bringing power to millions | Tombo Banda

The video discusses the impact of electrification in Zomba, Malawi, highlighting the benefits of electricity for education and the local economy. It addresses the challenges of electrification in sub-Saharan Africa, where many still lack access to electricity. Mini grids are proposed as a solution, offering localized energy systems that are quicker and cheaper to deploy. The video explores innovations to make mini grids more profitable, such as appliance financing and using second-life batteries. Case studies from Kenya and Tanzania demonstrate the potential of mini grids to boost local economies and improve living standards.
