We looked at PS1, PS2, Xbox, Xbox 360, Gamecube and Dreamcast power consumption last year, but now with the Wii and PS3 out, it's time to see who uses the most power.
Xbox 360 was the big loser last year, costing over twice as much to run as the nearest competitor, the original Xbox. As you can see, the Wii wins, but the difference between the other three are pretty much negligible. So yes, the Wii costs the least, burns calories, and saves you money over time. Like the complete opposite of our wives.
