An anonymous reader writes: Modern game consoles have a "standby" mode, which you can use if you want the console to instantly turn on while not drawing full power the whole time it's idle. But manufacturers are vague about how much power it takes to keep the consoles in this standby state. After a recent press release claiming $250 million worth of electricity was used to power Xbox Ones in standby mode in the past year, Ars Technica decided to run some tests to figure out exactly how much power is being drawn. Their conclusions: the PS4 draws about 10 Watts, $10-11 in extra electricity charges annually. The Xbox One draws 12.9W, costing users $13-$14 in extra electricity charges annually. The Wii U draws 13.3W, costing users $14-$15 in extra electricity charges annually. These aren't trivial amounts, but they're a lot less than simply leaving the console running and shutting off the TV when you aren't using it: "Leaving your PS4 sitting on the menu like this all year would waste over $142 in electricity costs."
