Liter of Light

Liter of Light is a global, grassroots movement committed to providing affordable, sustainable solar light to people with limited or no access to electricity. Through a network of partnerships around the world, Liter of Light volunteers teach marginalized communities how to use recycled plastic bottles and locally sourced materials to illuminate their homes, businesses, and streets. Liter of Light has installed more than 350,000 bottle lights in more than 15 countries and taught green skills to empower grassroots entrepreneurs at every stop. Liter of Light's open source technology has been recognized by the UN and adopted for use in some UNHCR camps. Liter of Light is the proud recipient of the 2016 St. Andrews Prize for the Environment, the 2015 Zayed Future Energy Prize, and a winner of the 2014-2015 World Habitat Award.
