Electricity in Mining: Power, Kilowatt-Hours and the Real Cost

An ASIC can run around the clock, so even a small difference in the price per kWh becomes a significant amount over the course of a month. Mining calculations should use the actual consumption of the entire system, not only the nominal watts printed on the box.

Watts are the rate of consumption; kWh is the bill

If a device consumes 1,500 W and runs for 24 hours, it will use approximately 36 kWh per day. The formula is simple: power in kW multiplied by operating hours. The result is then multiplied by the tariff.

Add the losses of the power supply, network equipment, ventilation, air conditioning and sometimes lighting to the ASIC. These costs may be small in a home calculation but become a separate line item in a farm.

1,000 W = 1 kW
1 kW × 24 h = 24 kWh
cost = kWh × tariff
with a dual-zone tariff, day and night are calculated separately

Why electricity matters more than an impressive hashrate

Two ASICs can have similar hashrates but different energy efficiency. Profit depends not only on the number of Sol/s or TH/s, but also on how many watts are required for each unit of computation.

In a Cambridge study, electricity represented more than 80% of the surveyed miners' monetary operating costs. That is why the tariff and power stability must be checked before buying hardware.
