What is the energy efficiency of a miner?

Miner energy efficiency is a metric that indicates how much electrical energy the hardware consumes to perform a given amount of computation, usually measured in joules per terahash (J/TH). Energy efficiency is a key parameter for assessing the profitability of mining equipment, as it directly affects operating costs and profitability.

Main aspects of miner energy efficiency:

The concept of energy efficiency:

- Energy efficiency is defined as the amount of electricity consumed to perform one unit of work, in this case, to perform one terahash (1 TH) of calculations.

Units of measurement:

- Energy efficiency is often measured in joules per terahash (J/TH). The lower the value, the more energy efficient the equipment is.

Dependence on the type of equipment:

- Different types of mining equipment have different levels of energy efficiency. ASIC (Application-Specific Integrated Circuit) miners are generally more energy efficient compared to GPU (Graphics Processing Unit) or CPU (Central Processing Unit) miners.

Examples of energy efficiency for various miners:

• Bitmain Antminer S19 Pro: one of the most energy efficient miners on the market, with an indicator of about 29.5 J/TH.

• Whatsminer M30S++: Also one of the energy efficient miners with around 31 J/TH.

• Antminer S9: older model range, with an energy efficiency of about 98 J/TH.

Impact on profitability:

Reduced operating costs:

- The higher the energy efficiency, the less electricity is consumed, which reduces the cost of electricity - one of the main expenses in mining.

Increase in profitability:

- Reducing electricity costs increases the overall profitability of mining, since most of the mined coins remain after covering electricity costs.

Long term sustainability:

- Energy-efficient equipment remains competitive longer, especially as network complexity and computing power requirements increase.
