Well, here’s a bit of news you can use while you spend 70 hours trying to finish Zelda. The Wii uses considerably less electricity than the PS3 or Xbox 360 and makes the PC look as wasteful as a Hummer with a hole in its gas tank.
At its peak, the Wii sucked down 18.4 Watts during gameplay as compared to 209.7 Watts in the PC and 199.7 Watts in the PS3. The total power consumption is basically a flat line when compared to the high peaks and valleys of the 360 and PS3.
The article also discusses power usage during video playback and other tasks, but it looks like the tiny Wii sips energy like a proper lady sipping juleps at the Kentucky Derby.
