To Unplug or not?

Question

I am getting conflicting information when I search for answers.

Some people claim that the act of unplugging and then plugging in again later uses more energy then just leaving a device plugged in.

Others claim that unplugging devices (computer, microwave etc) when not in use for several hours at a time, saves energy.

Does anyone really know which one is correct? Will I see a reduction on my electric bill if I unplug my microwave, computer etc. when not in use and overnight?

Answer 1

unplugging a light which isn't on does nothing, but a lot of electronic equipment uses power ( approximately 40% of the power they use when on ) even when off, it's called "standby" mode and uses a lot of electricity while not accomplishing anything. Things like the microwave that only have a readout won't do much, but your TV, stereo, computer and anything that has a standby mode does, even transformers for chargers use a lot, if they're not being used unplug them, or put them on a power strip and use the switch to shut them off.

Answer 2

Personally, I only unplug things when I leave for more than a couple of days.
Ultimately, unplugging something isn't going to make a noticeable difference on your electric bill.
Keeping your thermostat at reasonable levels, ensuring that your house is insulated properly, using florescent light bulbs, and turning off lights when not needed will provide more of a difference than anything else.

Answer 3

I unplug as much as possible. Definetely turn off things that are not in use. Just by doing simple things like this-i went from over 50dollars electric bill to only 25-30dollars per month.

Answer 4

Unplugging and plugging will not use more power. It may use less, but the amount will be too small to notice in your electric bill. Standby power use is extremely low compared to operating power.

Answer 5

unplug you may not see a noticeable difference in your elec. bill monthly but over the time span of your life it adds up. another thing is the collaborative effort of everyone that does unplug .... saves allot... look at the big picture.....
