Everything about The Light Up The World Foundation totally explained
The
Light Up the World Foundation (LUTW) is a non-profit humanitarian organization dedicated to providing lighting to poor people in remote areas who currently rely on
kerosene lamps or even
wood fires.
(External Link
) Apart from improved night-time lighting this gives health benefits and financial benefits.
LUTW is affiliated with the
University of Calgary,
Canada.
Programs
To date, lighting has been provided to more than 14,000 homes in 26 countries,

Technology
LUTW uses a combination of white
LED (WLED) lights or
LED lamps and a source of
renewable energy, typically
solar cells but alternatively person powered
pedal generators,
micro hydro or small
wind turbines. (The website uses the terms "pico hydro" and "pico wind turbines", implying extremely small scale.) The solar cells are suitable for providing electricity in remote areas, while the LED lights are chosen for their efficiency, durability, and relatively low cost. The efficiency of the lights means that relatively small solar panels are needed, reducing the capital cost.
Benefits
Although the lighting system is somewhat expensive for the villagers (approximately US$75)
(External Link) in the long term the cost of kerosene for lamps is eliminated. The elimination of kerosene smoke is a health benefit, and the light is also brighter than a kerosene lamp.

The LUTW website cites a
Lawrence Berkeley Laboratory paper, which argues that replacing kerosene lamps with
LED Lamps helps reduce
greenhouse gases. The paper says:
» The single-greatest way to reduce the greenhouse-gas emissions associated with lighting energy use is to replace kerosene lamps with white-LED electric lighting systems in developing countries; this can be accomplished even while dramatically increasing currently deficient lighting service levels. - Mills, 2002

It should be noted, however, that Mills doesn't discuss the one-off contribution to
greenhouse gas emissions from the production of components such as solar panels.
