The number of times I've seen mining have a double use leads me to believe that it isn't so clear cut as this statement. It generates heat, and I use that heat in my greenhouses and no longer need a heater. It's not the most efficient way to heat the greenhouses but it's more profitable that using a normal heater.
Other than individual-scale mining being an inefficient greenhouse heater, (or just heater in general) what are some of those dual uses you’ve seen so many times? On what scale compared to the bulk of mining activity?
