The U.S. Department of Energy (DoE) did a study of how much electricity was saved last year thanks to the use of LED in nine kinds of applications (various kinds of indoor lights, streetlights, etc). The numbers are impressive: “In 2012, about 49 million LED lamps and luminaires were installed in the nine applications.
