The Weerasuriya family are farmers near the village of Usgala in the Hambantota district of Sri Lanka. There are three generations living in the house. They used to have a car battery that could run two electric lights and a black and white TV. However, they had to take the battery into town twice a month to get it charged up, which was expensive and time consuming. They also had to buy kerosene for extra lights, as two electric lights were not always enough.
Now the family has a wind-powered system that keeps the battery charged for most of the year. They have more lights and the children are doing better at school as they can do their homework more easily. Thusara Sandaruwan, who is in year 10, has a battery-powered keyboard that he can use as much as he likes. And the whole family can now enjoy colour TV.
