While next week’s mid-summer cold snap won’t send you rushing for the nearest space heater, its origins are similar to the cold snaps that defined the brutal winter just past.
This would not make as big of a difference as it did last winter as miners then could provide a supplement to your heater, but today it would not be necessary to be heating your home, it would just be a little/lot cooler then normal. It depends on the setup. Some open air miners that use a lot of venting could really benefit from cool ambient and then not have to waste power on AC. Also, the power draw on the equipment is lower when the ambient operating temps are lower.
The generated heat might be useful but it generally has a much higher opportunity cost than something like natural gas. A few places use electricity for heating but most use some hydrocarbon fuel. If you happen to be using electricity for heat then mining just adds to your profit rather than taking away from it.
