BuckPalace A new energy-efficient lighting technology is gaining ground across the world, from Buckingham Palace to street lamps in the United States.
Light Emitting Diodes, or LEDs, were recently installed in chandeliers and exterior lighting at Buckingham Palace, The New York Times reports. Illuminating the entire facade of the royal residence uses less electricity than running an electric teakettle, with long-life bulbs that can last more than 20 years before needing to be replaced.
Though they are still more expensive than incandescant bulbs and newer compact fluorescent bulbs, technology is advancing rapidly. LEDs are more than twice as efficient as CFLs. Unlike compact fluorescents, LEDs are compatible with dimmer switches. And while fluorescent bulbs contain mercury, LED bulbs contain no toxic elements.
Experts say LEDs have the potential to reduce CO2 emissions for lighting by 50 per cent, or 6 per cent for energy use overall. A recent report by McKinsey & Company cited conversion to LED lighting as potentially the most cost effective way to reduce global warming."
