XBox 360 consumes 145 Watts simply turned on. Compare that with 4W for Playstation 1. What about when you are playing with them? Let's see how they are going to cost you in energy bills each year.

XBox 360 consumes 165 Watts while playing one single player race. PS1 consumes 6 Watt in comparison.

Assuming you play on average 14 hours a week or 2 hours a day and you leave your console turned on, you will spend around 20$ on your XBox 360 (116.48 kWh). A Playstation 1 will cost you less than a dollar.
