Supporters of the initiative included Intel Corporation, Google, Dell, EDS, the United States Environmental Protection Agency (EPA), Hewlett-Packard, Lenovo, Microsoft, Pacific Gas and Electric Company (PG&E), World Wildlife Fund and others.
The Climate Savers Computing Initiative operated in a manner similar to the U.S. Government's Energy Star program.
The Energy Star 4.0 standard for desktops, laptops, and workstations, which took effect in July 2007, requires power supplies to be at least 80 percent efficient for most of their load range.
In addition, it puts limits on the energy used by devices when inactive and requires systems to be shipped with power management features enabled.
TGG and CSCI fused their separate but closely aligned resources together to accelerate the implementation of energy efficiency and sustainability within the IT and communications industries.
