Study measures video game console power consumption

The study, published by a team of Carnegie Mellon researchers in the latest issue of the journalĀ Energy Efficiency, estimates that 100 million video game consoles sucked up nearly 16 terawatt-hours (TWh) of energy a year in the US in 2010.

Modern consoles have automatic shutoff options, but the study suggests that most people don’t turn them on.

If console makers were willing to push out a required firmware update that simply turned on such an automatic shutoff, the study estimates we could see a savings of 9.3 TWh of electricity usage every year, or $1.1 billion worth of energy spending.

And that’s just US numbers.
