I stopped reading as soon as they quoted that silly inaccurate UoC website that gets quoted over and over again.
Why? Because they even admit, in their own methodology (https://ccaf.io/cbeci/mining_map/methodology), that it is an extrapolation from less than 50% of the total hash. Even worse, is the pools they extrapolate from have been Chinese based. Although, that's changed over time, which invalidates their numbers even more.
Even still, there is no way to know how that power is generated, how much it offsets other power generation, etc... there are just too many variables to simply quote UoC.
