A study by Carnegie Mellon University researchers in Pittsburgh argues that new lighting technologies can become a key player in the portfolio of strategies needed to promote energy efficiency and to help reduce the emission of greenhouse gases.rn"Lighting our houses, streets, and commercial buildings constitutes more than 20 percent of total U.S. electricity consumption. LEDs can reduce consumption and the emission of greenhouse gases because of their high-efficiency conversion of electricity to visible light," comments Ines Lima Azevedo, a recent Ph.D. graduate from the university's department of Engineering and Public Policy (EPP), and a researcher at its Climate Decision-Making Center and the Electricity Industry Center.
