Really? I am under the impression that stolen electricity is one of the easiest ways that illegal grow operations are discovered.
As part of reading a meter I'm guessing an inspection of the meter box can be made. I'm guessing the modern digital electricity meters are able to report usage stats back to the company.
I'm using the word 'guessing' quite a lot here.
I believe that the power companies are more likely to be of use in detecting cannabis growers. I am sure that in some areas a mini arms race has gone on for decades with cannabis growers taking electricity from the 'other side' of the meter, so that nothing shows up on the bill. I am sure that electricity companies have also worked out how to compare electricity supplied versus electricity charged for in order to detect this, at least to street level, and, after that, the infra-red camera can come into play to detect the hot-roof, either by themselves or by the police.
Given a choice of stealing electricity for cannabis or bitcoins I would be surprised if the latter was more profitable. That said, bitcoin miners probably do arouse the suspicions of the authorities. Therefore it would be quite convenient to have a 'server farm' downstairs with a 'cannabis farm' in the loft. Therefore, when the authorities come round there is a plausible reason for the electricity usage.
Thus grow-ops are basically forced to find a way to connect to the grid in an unmetered, illegal fashion to avoid being reported.
Source? Reasoning?

I have sourced all the mcdonalds wifi in my area to grow marijuana. It's like how the sonar in the dark knight works.
All of the free wifi gets channeled in to my grow lights.
Similar issues will affect Bitcoin mining in the long run however I expect this to be more something that is achieved through mining bots and not through setting up server farms in houses with diverted electrical trunking.
As to electricity companies finding out, the issue here is that the 'noise' from loss of electricity in the network masks a specific house consuming huge amounts of electricity. I'm guessing there must be some sort of profiling going on to determine if an occupied house is using too little electricity.
