20% — Currently, about 20% of the world’s electricity is used for lighting.
75% — About 1/4 of that is for residential uses, and the rest is for commercial/industrial/governmental buildings.
5% — A typical incandescent bulb converts only about 5% of the electricity it uses into light, and it needs to be replaced approximately every 1,000 hours.
