The Department of Energy’s Pacific Northwest National Laboratory released a report September 7 concluding that LED light bulbs do the least environmental harm when compared with compact fluorescent lights and traditional incandescent bulbs. The report, taking into account the mining of raw minerals, disposal, manufacturing, and degree of electricity, found that traditional incandescent bulbs consumed the most electricity and had the worst environmental repercussions and that using a CFL or LED bulb could reduce environmental degradation by three to ten times, respectively.
