Do electronics that are plugged in but aren't in use still use power?

David B. Floyd and Carrie Webber of Florida Solar Energy Center (FSEC) and Lawrence Berkeley National Laboratory conducted a study of 633 devices. 95% of them, 598 consumed at least some power when off.

Power consumption when "off" ranged from 1 watt to more than 17 watts. The average standby power was 3.8 watts per device. The researchers estimate that the total house load due to such parasitic loads is about 50 watts.

It depends on what sort of off switch is used. If the device goes in standby mode when turned "off" it is not really off. If it is a hard switch, like a light switch it will not draw any electricity because electricity can't cross the open air. Other switches like televisions vary by device.

Yes... Most electronics are in a stand by mode when they are not on. It does not use a lot of power so it does not really affect your power bill. It uses the small amount so when you turn it on it goes on quicker. Quicker is better and makes everybody happier.

Some do, like computers. Most computers stay on if you press the "Off" button, but if it's a switch, then it won't use power, because the circuit will be open.

Some TV.'s and stereos do. Best thing is to hook them up to a surge protector and turn them off, then turn off the surge protector
