ENERGY STAR is a joint program of the U. S. Environmental Protection Agency and the U. S. Department of Energy helping us all save money and protect the environment through energy efficient products and practices. ENERGY STAR deals with products both for home and for business. Today I would like to introduce the office equipment to you. From computers and monitors to imaging equipment, such a sprinters and copiers that has earned the ENERGY STAR helps eliminate wasted energy through special energy-efficient designs. They use less energy to perform regular tasks, and when not in use, automatically enter a low-power mode.
    New Specifications for Many Office Products in 2007 bring new ENERGY STAR specifications for office and imaging equipment. This means it will be more difficult for computers, copiers, fax machines, mailing machines,multifunction devices(MFDS), printers, and scanners to earn the ENERGY STAR.
    The new ENERGY STAR specifications promise significant energy savings. In addition to reducing power use for the products themselves, the new specifications also set additional requirements for accessories. If an imaging product is sold with an external power adapter, cordless handset, or digital front-end, the accessories must meet current ENERGY STAR external power supply(EPS), telephony, or computer specifications. The serequirements ensure that the ENERGY STAR represents only the market’s most energy-efficient-products
    ENERGY STAR qualified office and imaging products use as much as 60% less electricity than standar dequipment. And using less energy keeps utility costs down. Over the next five years, these products will save Americans more than 5 billion dollars.
    Remember, saving energy prevents pollution. By taking a "whole system "approach and looking at the computer, its use, and components, these new specs will reduce the greenhouse gas emissions equal to about7 million cars.
