If you are reading this article that’s because you want a quick answer. Let’s go straight to it.
How much as Kw/h costs in your region? Power is priced in Kw/h. Get that information and come back or continue reading. I’ll be using the price from my region which is actually 0,1 450 €.
1Kw = 1000 W 1Kw = which is 3.6 million joules of energy. 1Kw can also be represented as 1KVa
Now, let’s use a 2015 Macbook 15 inch Model as an example.
According to google it uses 87 Watt (well they watts per hour).
How many Kw/h consumes a mac book?
(87 / 1000) = 0.087 Kw/h Price/h = 0.087 * 0.1450 = 0.012615€
If we leave our laptop on 24 over 365 days
0.012615 *24*365 = 110.50€
Laptops and smartphones require lower power. Eletrodomestic devices are a little bit more expensier.
PS4 Use case
Here’s another example from PS4.
(165 / 1000) * 0.1450 = 0.023925 (aprox 2cents per hour).
Hope it helps.
