Worldwide, grid-based electric lighting consumes 19% of total global electricity production.[1] The energy used to provide the world's light is 1 900 Mt of CO2 per year.[1] In Africa 60% the energy for lighting and other needs is derived from wood, leading to deforestation.[2] Combustion-based lighting is also a major cause of respiratory illness,[3] and generally of poor quality for reading, contributing to illiteracy.[4] All in all, plenty of reason to seek ways of providing more sustainable lighting everywhere. Certainly electric lighting will be a key part (in addition to Natural lighting).

  • LED lighting is becoming increasingly attractive. It is used in remote regions such as Nepal, by the Light Up the World Foundation as a healthier replacement for kerosene lighting. These lights are far sturdier than other types of lighting, especially compared to fluorescent lights.

Suggested projects

  • Compare light quality of different lights. What is the flicker rate of CFL? Are there better quality ones, comparable to the high quality but expensive tri-phoshpor fluorescent lights with electronic ballasts?[expansion needed]
  • Start a section on tri-phosphor lighting in the relevant Wikipedia and/or Appropedia article.)[expansion needed]
  • Compare the life expectancy of different types of lights - find peer-reviewed studies, if possible. What factors affect life expectancy?[expansion needed] (CFLs sometime don't last as long as expected in my experience, though I've been told by an efficient lighting expert that Phillips and Osram are more reliable than other brands. --Chriswaterguy · talk 19:19, 1 May 2007 (PDT))
