Many of our electronics look the same when they are running or off. Laptops with a closed lid, Digital Video Recorders (DVR’s) and Video Game Consoles such as the Nintendo Wii don’t look any different when running than when they are off… except for those little green, red and orange lights. Understanding what those lights mean is important to knowing when those appliances are on or off.
For instance the Nintendo Wii, has 3 different colored lights. Green means that is ON, orange in standby and still connected to the internet and red means that its off.
When metering the Wii with a Kill-A-Watt…
– Red light used 1.7 Watts
– Orange light used 9.2 Watts
– Green light used 16-20 Watts
When the Wii was on (Green light) the Wii was tested with and without a disk running, with and without connected to the internet and power consumption moved between 16 – 20 Watts.
So by leaving the Wii on (green light) you’re using 14 to 18 Watts more than necessary. That may not seem like much but over 24 hours that’s 384 Watts per day and 11,520 Watts per month.
The bottom line is if you don’t know when your appliances are truly off then you will be using more energy than necessary.
