Broadcom announced its support for the newly ratified IEEE Std. 802.3az-2010 Energy Efficient Ethernet (EEE) standard. 
Broadcom said its EEE-compliant products offer energy savings of up to 70 percent or greater and provide customers with end-to-end silicon and software solutions that enable faster deployment of energy efficient networks.
As part of its EEN initiative, Broadcom has developed its proprietary “AutoGrEEEn” technology to facilitate the adoption of EEE and provide a faster migration path for legacy networking equipment. AutoGrEEEn technology implements the EEE standard directly into Broadcom PHYs and allows them to be in EEE mode when interfacing with non-EEE enabled MAC devices, without requiring changes to those devices. This innovation allows customers to make existing network equipment EEE-compliant by simply changing the PHY devices.
