SANAA — For Wafa Al-Rimi, Yemen's revolution brought dark days. Though power outages are frequent in the country, Al-Rimi says during the past year's unrest, some days saw less than an hour of electricity.
Attempting to study for exams in those conditions got the 16-year-old and some of her classmates thinking: How could they keep the lights on?
"We were tired of darkness," Al-Rimi says. So, they turned to the sun.
