More commonly, they’re known for rotting brain cells, but video game consoles, like Xbox, Wii and PlayStation, cost gamers over $100 a year in energy, even when not in use. Why? Apparently people don’t turn them off when they’re done playing.

If switched off Sony PlayStation costs consumers only $12 a year, but if left on, PlayStation incurs an annual energy cost of $134. Nintendo Wii is the cheapest with a price tag of $3 and $10, respectively. And Microsoft Xbox is in the middle with $11 and $103.

Environmental groups suggest game-makers make power management options more accessible, implement automatic shutdowns and, quite frankly, implore people to be responsible and turn off their systems when done with them. Didn’t your mom teach you that!
