energy savings

DOE Report December 2006 “Energy Savings Potential of Solid State Lighting in General Illumination Applications”

Teralumen-hours of Annual Lighting Demand by Light Source Technology


Fluorescent usage already far exceeds incandescent.
This aligns with the fact that 51% of energy consumption for lighting is in the commercial sector.

The U.S. Department of Energy estimates that energy consumption for lighting can be reduced by over 20% by 2020 through the use of solid state LED-based lighting.
