The good and bad of using LEDs

I am currently exploring how I can use LEDs for my home after converting all of my lights to CFDs. While more energy efficient, CFDs contain mercury  and require special disposal handling compared to incandescent bulbs. So far, I am still keeping 1 used CFD and 2 florescent tubes until I found a way to dispose of them safely. Using LEDs will be the same.

LED Bulb Technology Widening Gap in Energy Efficiency, Report Says

Yale Environment 360Published on Date September 10th, 2012 by Yale Environment 360

While today’s light-emitting diode (LED) bulbs are slightly better for the environment than compact fluorescent lamps, the energy efficiency gap will widen over the next five years as the technology and manufacturing methods of LEDs improve, according to a new report.

In an analysis of the impacts of the light technologiesin 15 categories — including the energy and resources required to manufacture, operate, and dispose of the bulbs — researchers at the U.S. Department of Energy’s Pacific Northwest National Laboratory found that CFLs caused slightly more environmental harm than existing LED technologies in all but one of the areas studied.

The one exception, they said, was hazardous waste generation because existing LEDs utilize a component, called a heat sink, which requires mining, refining, and processing of the aluminum. Improved efficiencies in emerging LED technologies, however, will reduce the amount of heat produced and, in turn, the size of heat sink required. As a result, they say, LED bulbs are expected by 2017 to have 50 percent less environmental impact than today’s bulbs and 70 percent less than existing CFLs.
