Electricity is charged whenever you use it or not, so very unlikely, but sure, they can find uses for it. Although they are not going to make that much money compared to claude code subscriptions.
the datacenter has a fixed cost for power, industrial power is not consumer power especially at large scale. Scale really kicks in if you own your power plant (ex: hydro, wind, solar).
For an example, even if you have a fixed power budget at the data centre level, you still have opportunity costs: if you turn some unused GPUs off, you can run other things hotter.
