In a world where access to electricity remains a privilege for many, a grassroots movement has emerged, harnessing the power of simple, sustainable solutions to bring light to those living in darkness. Liter of Light USA, a non-profit organization, is at the forefront of this global initiative, dedicated to providing affordable and eco-friendly lighting solutions to underprivileged communities worldwide.

Through their innovative approach, Liter of Light USA is not only addressing the immediate need for illumination but also fostering a ripple effect of positive change. By empowering local communities with the knowledge and skills to build and maintain their own solar-powered lighting systems, the organization is paving the way for sustainable development, environmental stewardship, and economic empowerment.

The Liter of Light Movement: A Bright Idea Born from Necessity

The origins of the Liter of Light movement can be traced back to 2002, when Brazilian mechanic Alfredo Moser stumbled upon a simple yet ingenious solution to illuminate his home during a period of economic hardship. Inspired by the principles of refraction, Moser filled a plastic bottle with water and a few drops of bleach, creating a makeshift “solar bottle bulb” that could refract sunlight and provide illumination equivalent to a 55-watt incandescent bulb.

This innovative idea quickly gained traction, and in 2011, Illac Diaz, the founder of the MyShelter Foundation in the Philippines, recognized its potential to address the pressing issue of energy poverty. Diaz launched the Liter of Light program, which aimed to bring Moser’s invention to underprivileged communities worldwide, empowering them to build and install these solar bottle lights themselves.

The Liter of Light USA Mission: Empowering Communities Through Sustainable Lighting

Inspired by the global Liter of Light movement, Liter of Light USA was established with a mission to educate and raise awareness about this innovative solution, while also supporting its implementation in communities across the United States and beyond.

The organization’s core objectives are threefold:

  1.
