This may convince you to turn off your consoles. According to research conducted by Australia-based Choice, folks who don't physically turn off their PS3 (by flipping the power button) will add $248.28 to their electric bill a year. An idle Xbox 360 costs $184.32 in energy consumption. Idle Nintendo Wiis cost a mere $23.26.

The only consumer electronic product tested that rivals the PS3 is Plasma TVs, which cost $232.10 a year if left powered on.

Definitely a persuasive argument to put your consoles on a power strip and turn that off at the source when you're done. There's no need for all these devices to be on "Standby" all the time
