The majority of Tanzania's population live without electricity. Lighting in rural areas is provided by kerosene lamps whose smoke damages the lungs, or by poor-quality flashlights. One Japanese firm is bringing dependable electricity to these areas. Every small village has a small store called a kiosk. Here solar energy is used to charge lights during the day. At sunset, they are rented out to residents. The lights also include a charging station for mobile phones which are vital to life in these areas. Now in its 4th year, the firm has expanded operations to include around 900 kiosks. The bright, safe lights are used on nighttime market stalls, to light domestic chores and help children study. About 1.5 million people have benefited from these lights. Explore how Japanese and Tanzanians are working together to bring light to areas with no electricity.
