LED's can provide an affordable and swift means of developing the living standards of many Africans and populations in other Third world countries.
From the article:
"The number of people without adequate light is greater than the entire world population when Edison invented the light bulb."
"There are 1.7 billion impoverished people worldwide who burn kerosene for light. Fuel for this purpose costs $40 billion and emits 200 million tons of greenhouse gases per yearԗequivalent to the emissions from 30 million cars. While Americans spend a fraction of their income on light, people in the developing world devote 10 to 15 percent of theirs to itfor little return. Fuel lamps account for 17 percent of global lighting costs but provide less than one-tenth of one percent of global light output."
