Every once in a while I will run into an article online that claims the Wii is the “greenest game console”. Sure, the Wii uses very little power when your are using it compared to other consoles, but it uses an absurd amount of power when it is in standby mode compared to the standby mode of other consoles.
By default the Nintendo Wii consumes 11 watts of power while in standby. This number is significantly higher than the standby power used by other game consoles. For instance, the Xbox 360 only consumes 2 watts of power in standby. The reason the Wii consumes more power in standby is because of the WiiConnect24 standby connection, that is enabled by default.
