Currently, fuel-based lighting in the developing world is a
source of 244 million tons of carbon dioxide emissions to the
atmosphere each year, or 58% of the CO2 emissions from residential
electric lighting. Also, subsidized kerosene for domestic lighting
sometimes finds its way into vehicles with additional environmental
consequences.
Rising CO2 and other green house gas concentrations in the
atmosphere, resulting largely from fossil-energy combustion, are
contributing to the global warming and to changes in climate [2].
Climate-destabilizing carbon dioxide emissions would continue to
rise, attracting attention for the long-term sustainability of the
global energy system. In 2030, energy-related CO2 emissions
would be 52 per cent higher than today and need to change these
outcomes in order to get the planet onto a sustainable energy path.
To address the greenhouse gases (GHGs) emission problem,
judicious and intelligent use of energy resources are recommended.
The best option is to use the more efficient and energy
saving devices and appliances.
New types of light sources and technology are desired to
convert energy directly into visible light at room temperature
without any emission of green house gases. In this context, solarpowered
compact fluorescent (CFL) and white LEDs provide the
solution with less power consumption and almost no environment
contamination. The single greatest way to reduce the greenhouse
gases associated with the lighting energy use is to replace kerosene
lamps with solar-powered CFL and white LED lighting systems in
developing countries
