Even when they’re powered off, laptop and cell phone chargers, TVs, stereos, and other electronics continue to draw electricity from the grid if plugged in.
One great way to save energy would be to unplug your laptop and cell phone charger when you’re not using them. More effectively, you could plug your cell phone charger, laptop charger, printer, TV, stereo (and/or any other appliances you don’t need when you’re not in the room) into a surge protector. When you leave the room, simply flip that switch off (or better yet, unplug the power strip!), and save energy without the trouble of having to unplug a mass of cables and plugs!
At the very least, when you happen to go out of town for a few days, be sure to unplug your TV, stereo, desktop computer, and/or any other large appliances that won’t be used while you’re gone.
