Many people know that CFLs (those wonderful new light bulbs) use only one fourth as much electricity as incandescent light bulbs, but did you know other household appliances have a similar range of efficiencies?
Among industrial countries, Japan’s Top Runner Program is the most dynamic system for upgrading appliance efficiency standards. In Japan’s system, the most efficient appliances today set the standard for those sold tomorrow. With this program Japan planned to raise efficiency standards between the late 1990s and the end of 2007 for individual appliances by anywhere from 15 to 83 percent, depending on the appliance. This is an ongoing process that continually exploits advances in efficiency technologies.
