As the sun sets, Shama Bibi switches on her solar lantern and starts sewing clothes for the upcoming festival of Eid. Not long ago, she used to sit idle as soon as darkness sets in. She and other residents of her village outside Bahawalpur, now also remain busy in their activities after sunset. This might not sound like a big deal to someone living in a developed country. But in the far off villages of Pakistan, however, where people barely have access to electricity, these solar lanterns are truly a blessing.
