I'm coming from the energy side, the main cost of miners is the price of energy.

Miners have many business models around energy, some of them are:

1. Allocating demand behind the meter of generators that are not able to transmit their full capacity.

2. Demand response to improve the transmission system.

3. Allocating demand where small communities pay a lot of many for their energy, because building a big power generator wouldn't be cost effective, so joining ventures with energy providers ND selling excess energy to small communities is been explored.

Off-grid projects, whwre the miners is completely independent from de grid and owns the energy generator. That gives the miner about 30+ years of energy for 7-8 mining cycles.
