Hard appliances such as your modem or TV use 7 to 14 watts per hour even when they are not in use! Of course, you can manually unplug these appliances, but honestly, there’s just no way you’ll be able to remember to do that every single time you leave the house! So here’s the solution: invest in a power strip so your appliances don’t waste energy when you’re not using them. If hitting the switch doesn’t really appeal to you either, try the new switch that automatically powers down products that are not turned on or are in standby mode
I've heard about a device like this. but never used it.. How can this small device possibly reduce my electricity bill?
