categories: - Misc

If you draw 100 W / hour on average

100W x (8760 hours per year) / 1000 = 876 kWh

Thus : 1 kWh = 0.114155 W on average 1 W on average = 8.76 kWh

The power here costs 0.1429 € per kWh.

876 kWh * 0.1429 = €125.18

Leaving something on drawing 100W in average costs €125 per year.
