My SSDs use negligible power at idle, I only noticed a 1w increase when I installed two. Almost ‘free’. Also your 0.14kwh is almost certainly just the cost to generate the power minus the delivery fees. Where I live the delivery fees double my true per kWh cost. Double check your bill and divide your monthly consumption by your monthly payment to find the real cost.
Thats friggin bananas. Do you live somewhere with lots of hydro power? Your cost is less than 1/3 mine…
