corrugated iron roof house at Granizal neighborhood in Bello
municipality, Antioquia, Colombia on November 21, 2014. The
foundation "A Liter of Light" aims at improving the quality of
life of families which have been displaced from their land due
to the armed conflict, through lighting their homes with
alternative energy. Recycled plastic bottles filled with water
and chlorine are placed across the corrugated iron roofs so that
they illuminate the inside when there is daylight. For public
lighting there are solar panels held up by wooden posts, which
retain energy during the day and have a batteries and 5-watt LED
bulbs covered by plastic bottles which work as a diffusers. AFP
