When you think about things at home that consume lots of power, you probably don't think of your humble Internet router. But leave it turned on all day, and it matches the electricity needs of your refrigerator.

For that reason you should pay attention to the energy efficiency of a router before you buy it, and make sure it has the lowest possible power consumption when turned on and when in stand-by mode.
