2 STANDBY & NO-LOAD ENERGY WASTE IS A WORLDWIDE PROBLEM Billions of dollars of energy are wasted annually due to inefficient standby and excessive no-load power consumption. Recently, governments have developed programs and guidelines to reduce this problem. USA CAN YOUR PRODUCT MEET THE WATT STANDBY EXECUTIVE ORDER? Each agency, when it purchases...shall purchase products that use no more than one watt in their standby power consuming mode. CAN YOUR POWER SUPPLY MEET THE EUROPEAN NO-LOAD POWER TARGETS?
