More than 40% of all homes in the United States contain at least one video game console, consuming an estimated 16 billion kilowatt-hours per year. Through better habits of powering off consoles or using energy saving features, we could save approximately 11 billion kWh of electricity per year and cut our nation's electricity bill by more than $1 billion per year. That amount is the equivalent of removing emissions of more than 7 million tons of CO2 each year.
According to the Natural Resources Defense Council report, the single most effective way to save energy is to power down your system when you are done after saving your game. According to the study, the Nintendo Wii is the most energy efficient with the Sony Play Station 3 consuming the most energy. Here is the breakdown from the report:
- Nintendo Wii
Uses an average of just 16 watts in active mode. Turning off the unit when not in use saves about $7 a year.
- Microsoft Xbox 360
Consumes an average of 119 watts in active mode. Turning off the unit when not in use saves about $129 a year.
- Sony PlayStation 3 (PS3)
Burning through an average of 150 watts in active mode, the Sony PS3 draws the highest amount of power of the video game consoles on the market in 2007. In October 2008 Sony introduced a power management feature via online update, but it too is disabled by default. Turning off the unit when not in use saves about $145 a year.
- Playing DVDs in your gaming console may cost you
Playing a DVD movie in your gaming system may be more expensive than playing it in your DVD player. As stated above, the Wii, Xbox, and PlayStation all use a different amount of energy. A DVD player, according to the Department of Energy, may use between 17 - 21 watts or 20 - 25 watts of energy.
