For starters, new Linksys wireless N routers (WRT310N, WRT160N, WRT610N, WRT110, and WRT54GS) will be encased in a lot less packaging. And what packaging is left will be made from 80 percent recycled materials and printed using vegetable and soy based inks. The company estimates that this step alone is the equivalent of taking 3,000 cars off the road each year.

A good start, but the real impact to the electric bill comes in the form of Energy Star rated power adapters. Linksys explains:

The energy consumed by the power adapters has been cut almost in half. For example, a router used 4.6 watts of power and a new router with one of the ENERGY STAR certified power adapters can use as little as 2.6 watts of power. This equates to a power reduction estimation between 14MW and 17MW (based on Linksys' top 10 shipping product volume, which is approximately 11,000,000 units). That is enough power to light 14,000 houses for one full day.

Your mileage may vary, but considering that most home routers stay on 24/7 (mine included), every little bit helps.

Thanks Dan!
