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.
The WiiConnect24 standby connection allows your Wii to stay connected to the internet all the time and allows you to receive WiiConnect24 content even when your console is in standby. The obvious solution to this excess standby power consumption is to turn the feature off:
Goto your Wii Settings, then page 2, then click the WiiConnect24 button, then click the Standby Connection button, the click the off button.
That is easy enough, and will reduce the power consumption of the Wii when in standby to 1 watt. However, Nintendo’s problems don’t stop there. Once you have disabled the WiiConnect24 standby connection, you can no longer use the weather or the news channels! I don’t understand why Nintendo would do this, as there is no technical reason for this to be.
I would like Nintendo to release a firmware update for the Nintendo Wii that will change two things:
First, I think Nintendo should disable WiiConnect24 standby connection by default. This is more of an advanced user option and does not need to be on by default.
Second, I want to be able to use all of my channels with the WiiConnect24 standby connection off. There is no reason that I shouldn’t be able to do everything with my console when it is on.
By doing a simple update like this, Nintendo could save 929,000 Mega-Watt/hours of electricity per year , and claim it’s place as “greenest console”.
If you feel that Nintendo should make this update, please contact them about it.
 If you leave your Nintendo Wii plugged in all year long, even if you don’t use it at all, you will use 96.4 kilowatt hours of electricity per year with WiiConnect24 standby connection turned on. (11 watts * 24 hours/day * 365 days/year) If you turn WiiConnect24 off, you will use only 8.7 kilowatt hours of electricity per year. (1 watt * 24 hours/day * 365 days/year)
According to Wikipedia there are 10.6+ million Nintendo Wiis worldwide. That means that if everyone turned off the WiiConnect24 standby connection, 929,000 mega-watt/hours of electricity per year would be conserved.
