Power-hungry consoles: which fares best?
In November 2008, the Natural Resources Defense Council released this report on the energy usage of the top three video game consoles. They claim this report
“provides recommendations for users, video game console manufacturers, component suppliers and the software companies that design games for improving the efficiency of video game consoles already in homes as well as future generations of machines yet to hit the shelves.”
Most people today don’t think twice about leaving home appliances on when not in use. Game consoles often get left on because the player is in the middle of a level and cannot save yet needs to do an important life task like eat or sleep. I can’t say I’m not guilty of doing that in the past. It just takes time and patience to get into habits for things like this. I’m sure for people who pay their own bills and own a video game console, the biggest reward of turning their system(s) off when not in use is the money they can save.
The energy usage for the top three consoles is as follows:
+ Annual energy use (kWh) for users who turn console off after use
- Annual energy use (kWh) for users who turn console on
Nintendo Wii
+ $3
-$10
Microsoft Xbox 360 (revision 2007)
+$11
-$103
Sony PlayStation 3 (revision 2007)
+$12
-$134
Microsoft Xbox 360 (launch 2005)
+$14
-$143
Sony PlayStation 3 (launch 2005)
+$15
-$160
I almost feel as though this data is not surprising considering the size of each console (Wii<Xbox<PS3) but with the recent announcement of the PS3 slim, I am curious to know how it’s new size would affect it’s energy consumption.
The biggest thing game players can do to conserve their energy is make sure all their entertainment electronics are plugged into a surge protector that can turn everything off with the flip of a switch and make sure to switch games off when not in use. The surge protectors work great overnight and on vacations to prevent electronics from leeching power while they are off and you are away.

According to a review of the PS3 slim by PC Magazine, the revamped system actually has lower energy consumption:
Using a Kill-A-Watt meter to measure power consumption, the new PS3 used 71 watts during Blu-ray movie playback, while the older model consumed 104 watts, making the newer model 32 percent more efficient. To compare, a 42-inch LG LED HDTV consumed about 140 watts while playing back the same scene.
This is certainly good news, but I’m somewhat surprised that Sony waited so long to make these changes. My guess is they wanted to sell as many of the larger systems at the higher price point before rolling out a cheaper overhauled version. Didn’t they go awhile before the new style PSP came out? Hm.
