Light-emitting diode (LED) lighting has the potential to save energy and improve lighting quality and performance beyond that of many conventional lighting technologies. However, to truly gauge the full energy and environmental impacts of a lighting technology, its materials, and energy resources must be traced over the entire lifecycle. The report "Review of the Life-Cycle Energy Consumption of Incandescent, Compact Fluorescent, and LED Lamps" is the first installment of a larger U.S. Department of Energy (DOE) project to assess the lifecycle environmental and resource costs in the manufacturing, transport, use, and disposal of LED lighting products in relation to comparable traditional lighting technologies.
