LED renovations and retrofits: Evaluating codes and costs

According to the U.S. Dept. of Energy (DOE), LED lighting can have the greatest potential impact on energy savings in the United States. The DOE estimates that widespread use of LEDs could save the equivalent of the annual electrical output of 44 large, 100-MW electric power plants for a total savings of more than $30 billion at today's electric rates. This solid-state lighting technology that uses a semiconductor to convert electricity into light is one of the most energy-efficient and durable lighting technologies today. In fact, LED light sources can be six to seven times more energy efficient than conventional incandescent lights, allowing for significant reductions in energy use.
