electrical

...short answer: No.

I am not sure how you turn off a clock without unplugging it, but anyhow here is the long answer.

Almost all electronics today draw power when they are off or in reality in a sort of hibernate state. Your typical tv or radio has to power some of the circuits to look for the command from the remote control or the on button. Additionally any power supply transformer that you plug into the wall like a cell phone charger draws power even when your phone isn't connected to it. These devices have no way built into them to disable this. Your cheapest option other than unplugging the device, is to get a power strip with an on off switch, and switch it off when not in use. Their was an effort to design electronics to waste less electricity, as often more circuits are powered than necessary just to listen for the turn on signal from the remote. I am not sure where this is now, but their is defiantly room for improvement in electronics design of consumer devices when powered off. Here is a link to an article I found, I am sure their is lots more info on this elsewhere online.

Well think about it, I'll use a stereo tuner for example. Would you want to have to completely recalibrate (retune) your home theater system everytime you turned it on, or reset the music stations? Most of this is handled by an RTC (real time clock). This is a battery back up that supplies power to NVRAM which stores this information. Not all devices have this. For instance, say you have a radio with a RTC, you can unplug it, and plug it back in later and it will have retained the info in the NVRAM and your radio stations will still be programmed.

Yes if your electrical devices are plugged in and turned off they are still using electricity. The amount that they consume in their off state is very little. I do not think that the power used would amount to much on you bill. Especially compare to the time spent running around the house resetting the clocks and settings on your TV. Plus most device have back up batteries. These batteries if the device is unplugged will be draining down to maintain your settings. When you plug the devices back in for use you will be drawing more power than usually to recharge the batteries. So you don't save anything there.

"The amount that they consume in their off state is very little."

I think you would be surprised at how much power some electronics use when its off. Many devices use only half as much power when they are off vs when they are on, some even more. Cable boxes used to be a big offender, I remember mine used to be burning hot even when it was off.

Yes.In tv sets the devices like LOT/a VOTAGE step down device, eventhough tv is not ON will dissipate some energy in the form of heat.

<...Is there any way to stop this besides pulling the plug....>

Nope. If it runs warmer than ambient temperature, it's costing more than ambient expenditure.

Once again, I would like to thank everyone for their comments on "electrical" . At least now, I'm not going to worry about paying to much. Thanks again, Rich
