The global cost of lighting energy is approximately $230 billion per year, of which $100 to $135 billion can be saved with present-day technologies. Approximately 70% of these savings are to be found in electric lighting, with the remaining 30% in kerosene-based lighting in the developing world. The electricity savings are equivalent to the output of 240 to 385 power plants, and the kerosene savings are equivalent to 1.7 million barrels/day of oil production. 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.
