D-Link's been sipping power of late with its newish DWA-643 and DWA-556 desktop "Green Ethernet" switches, and now it's shipping those power savings upstream to its DIR-655 Xtreme N Gigabit router and DIR-855 dual channel routers with freely downloadable firmware updates. We'd scoff, but that's a power savings of 32 percent and 41 percent, respectively. It might only shave a few cents off those electric bills, but hey, you can always melt that copper down to make arrows for the coming apocalypse.
