Light Up the World Foundation 5117025 224593388 2008-07-09T15:52:55Z Thorseth 461897 linked to fire instead of woodfire 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 wood [[fire]]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]Countries such as Sri Lanka and South Africa. ==Technology== LUTW uses a combination of white [[Light-emitting diode|LED]] (WLED) lights or [[LED lamp|LED lamps]] and a source of [[renewable energy]], typically [[solar cell]]s but alternatively person powered pedal [[Electrical_generator|generator]]s, [[micro hydro]] or small [[wind 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 lamp|LED Lamps]] helps reduce [[greenhouse 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. ==See also== *[[Appropriate technology]] ==External links== *[http://www.lutw.org Light Up the World Foundation] - LUTW official site. *[http://www.lutw.org/illum_globalchallenge.html The Global Challenge - Reducing Dependence on Kerosene for Lighting in the Developing World] -from LUTW official site <!--website being updated, this link doesn't work--> *[http://www.earthsky.org/shows/show.php?date=20060411 Foundation brings light at night to rural poor] Earth & Sky radio program, April 11, 2006 *[http://www.energymanagertraining.com/equipment_all/lighting_system/WLED.htm What are WLEDs?] - by Dave Halliday, Founder Director of LUTW *[http://eetd.lbl.gov/emills/PUBS/Global_Lighting_Potential.html Global Lighting Energy Savings Potential] - by Evan Mills, Lawrence Berkeley Laboratory, 2002 {{international-dev-stub}} [[Category:Appropriate technology organizations]] [[Category:Development charities]] [[Category:Renewable energy organizations]] [[Category:Foundations]]
