Power supplies don’t just convert energy; they consume it. Anything with a transformer — those black boxes on power cords — draws power as long as it’s plugged in. And because of poor design, these boxes waste up to three-fourths of the electricity that passes through them.
Does leaving power cord plugged in use electricity?
According to the Energy Saving Trust, any switched on charger that is plugged in will still use electricity, regardless of whether the device is attached or not. The amount of electricity produced from this only costs a few pence, but it will shorten the shelf life of the charger.
Does using extension cords use more electricity?
No, an extension cord (short of long) does not draw (consume) any power so there is no way for the cord itself to increase your bill. An extension cord only conveys power to the devices plugged into it – if those devices are actually turned on.

Do extension cords reduce power?
Yes, it is less powerful. An extension cord (and any length of conductor) has a resistance. That resistance will reduce the voltage delivered and thus reduce the power delivered – its basic Ohm’s Law. The practical effect of this is negligible under essentially all situations, but it is real none the less.
Should a refrigerator be on an extension cord?
Using a grounded extension cord with a three-prong plug is always the best choice for major appliances including refrigerators. Since the 10-gauge cord is an extra heavy-duty extension, it makes the best choice for big power loads like a refrigerator.
