What are the ENERGY STAR requirements for computers and monitor power management capabilities?
Since 1994, EPA has defined ENERGY STAR specifications for computers and monitors that call for lower energy use and require that power management capabilities be enabled when shipped. ENERGY STAR-labeled computers are required to power down to 15 percent of their maximum power use. ENERGY STAR-labeled monitors are required to power down to 15 watts or less after 15 to 30 minutes of inactivity and down to 8 watts after 70 minutes of activity. A new ENERGY STAR specification for monitors that goes into effect on January 1, 2005 requires that the monitor only draw 4 watts or less in sleep mode. By January 1, 2006, the sleep mode is 2 watts or less. The new ENERGY STAR specification also includes specifications for active power use in monitors.
