When the Beatles sang the song “Revolution,” they probably weren’t thinking about changing lightbulbs. But LEDs (light-emitting diodes) could “revolutionize how we use light,” according to two professors from the Rensselaer Polytechnic Institute in a recent article published in Optics Express.
Researchers working on alternative lighting solutions say LED lights will replace the common lightbulb in the coming years. e!ScienceNews reports, “If all of the world’s lightbulbs were replaced with energy-efficient LEDs for a period of 10 years, researchers say it would reduce global oil consumption by 962 million barrels, reduce the need for 280 global power plants, reduce carbon dioxide emissions by 10.68 gigatons, and ultimately result in financial savings of $1.83 trillion.“
