- Light Up the World Foundation
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 lamp s or even woodfire s. [http://www.lutw.org/illum_globalchallenge.html] 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, [http://www.lutw.org/about.htm] such as Sri Lanka and South Africa.
Technology
LUTW uses a combination of white LED (WLED) lights or LED lamps and a source of
renewable energy , typicallysolar cell s but alternatively person powered pedal generators,micro hydro or smallwind turbine s. (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) [http://www.earthsky.org/shows/show.php?date=20060411] 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. [http://www.lutw.org/illum_globalchallenge.html]
The LUTW website cites a
Lawrence Berkeley Laboratory paper, which argues that replacing kerosene lamps with LED Lamps helps reducegreenhouse gas es. 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 [http://eetd.lbl.gov/emills/PUBS/Global_Lighting_Potential.html]It should be noted, however, that Mills does not discuss the one-off contribution to
greenhouse gas emissions from the production of components such as solar panels.ee also
