Efficiency and the energy mix
The Cambridge Digital Mining Industry Report, published in 2025, estimated average SHA-256 ASIC efficiency at 28.2 J/TH using data through June 2024. Study participants reported 52.4% sustainable energy in their energy mix.
These figures are not a permanent global counter; they come from a particular sample. They do show the direction, however: miners are looking for cheaper, more flexible and cleaner energy.
Mining as a flexible load
A farm can reduce consumption during shortages or high-price hours and return to work when electricity is cheaper. This makes mining a potentially useful partner for some power systems, but only under the right tariffs and rules.
At the same time, large operators are exploring HPC and AI as a way to diversify. For a home miner, this is not a ready-made income recipe; it is an infrastructure trend.
