Liter of Light – Fighting Energy Poverty by the Simplest Way, With a Plastic Bottle

Liter of Light – Fighting Energy Poverty by the Simplest Way, With a Plastic Bottle

Today 1.3 billion people do not have access to energy, or a fifth of humanity. When facing this situation people rely on expensive and dangerous alternatives solutions such as firewood, kerosene lamps or fuel generators. These alternatives are both harmful to the environment and to people’s health.

Millions of people, mostly children, die every year due to indoor pollution. There is a close relationship between development and access to energy. Poverty energy is a huge obstacle towards access to both education and health.

How do you make affordable, reliable and clean energy available for the bottom of the pyramid? 

Illac Diaz, founder of Liter of Light, thought of a solution where the materials could be found locally, wherever you are: plastic bottles. Old plastic bottle filled with water and chlorine, you get a 55-watt solar bulb that refracts sunlight!

Thanks to simple technology and solar panel, you can also light up a room or streets at night!

Liter of Light’s open source technology has been recognized by the UN and adopted for use in some UNHCR camps. The movement Liter of Light has been awarded for its innovations and sustainable solutions tackling global warming and poverty. 

The Liter of Light is both a day and night solution that provides passive daylight as well as charged evening solar lights such as lanterns, house lights, and streetlights through local skills building and sourcing electronic parts for building the products at the base of the pyramid instead of merely retailing imported finished products.

It has been acknowledged by the United Nations Framework Convention on Climate Change (UNFCCC), for its initiatives at the conference in 2011 at Durban, South Africa and it has also been honoured with the ZAYED Future Energy Prize in January 2015. It is also a winner of the 2014-2015 World Habitat Award. 

Illac Diaz also founded My Shelter Foundation, based in the Philippines. MyShelter Foundation aims to create affordable and replicable technologies to empower grassroots entrepreneurs to generate wealth through sustainable solutions to move out of poverty. 


Presently, the fund raising campaign of Liter of Light is live at Indiegogo for a goal of $ 27,000. The money will be used for the project in Ivory Coast to buy the required materials to build the lighting systems, finance human and material logistic, install the lighting systems at people’s homes and in the streets.

Besides reducing and reusing plastic waste, this lighting systems use renewable energy for better environmental value and social impact.
