Calculation of the energy consumption. E (kWh/day) = P (W) x t (h/day) / 1000 (W/kW). It means that the energy in Kilowatts hours in a day is calculated by multiplying the power in Watts (W) by the number of times (hours) used in a day then divided by one thousand watts per kWh. The Energy Consumption Calculator is useful and can help you ...

So using this to calculate the energy needed to store something for a year (times 24 and 365,25) gives us 5.7 kWh for HDD and 10.5 kWh for SDD. However cloud providers usually provide redundancy via RAID or backups which is not taken into account in this calculation, so that at least doubles the footprint.
