Laptop vs Desktop on electricity bills

[manolis kokotsakis]

What is the difference of using a laptop vs a desktop (without a graphic card on it ) on electricity bills ?
I mean , both to use for office work, not gaming ?

The cost of one or two cases of beer, annually.

For instance....
My little HTPC, which is on a power usage par with a very low end laptop.
Idles at around 11.5 watts

My main PC idles at around 60 watts.

Using Electricity Bill Calculator from RapidTables, at $0.12 kWh cost:
Running at idle 24/7 for a year:

The HTPC costs $12.62/year
The main PC costs $63/year

So $51 difference, total, on an annual basis.


If you were to, instead, work with 8 hours use per day...

HTPC - $4.20
PC - $21
That is total annual cost.

$17 difference.

"Office work" doesn't stress a desktop PC all that much, so it won't really be much above "idle" usage.

A lower end desktop is likely going to run about 30-40W of power. However you have to add in a monitor, which can throw another 10-15W on top of that.

A laptop for office work (like say a Dell XPS/Inspiron) will typically take about half that if plugged in and fully charged.
