Yes, absolutely….as long as your electricity is working, no matter if you switch the appliance off or the light bulb is blown, the electricity is still going.
You should turn off/unplug as many appliances and electronics as you can. For example, using the remote control to switch off appliances like your TV and video doesn’t stop them from using power if there’s a red light or timer display showing, it’s still drawing electricity. Using the remote only puts appliances in stand-by mode.
I have a wall switch on every wall in every single room in my home. For example, once I leave my kitchen, I hit the switch, it turns off every electrical plug in my kitchen, it keeps me from unplugging my appliances constantly (I do have to reset my clock on my stove & microwave, which can be a drag.) Same thing goes for my living room, tv, dvd, lamps. The only thing not on that circuit is my computer which I have a surge protector and I cut it off seperately.
So, if your electricity in your home is running, the appliance you have plugged in to your electrical outlet is still using electricity, even if it is in off mode, then it is causing you to pay more money to the electrical company.
