Why is their claim nonsensical? Just do the math, politics and countries are not relevant. Take the hash rate, transactions per second, and power consumption of any mining rig. The current hash rate is about 11 ExaH/s (; 11 Million TH/s) supporting approximately 3.81 transactions per second. Meaning power to support about 3 ExaH is used, for every transaction. Taking a decent mining GPU youre at about 3MH/J. To perform this amount of hashing with this example it would take 3TJ. Or for comparison, the energy in about 170 barrels of oil, for one Bitcoin transaction. The numbers may be a bit off, but they're not off by a factor 100, and my house for sure doesn't even need 1/100th of this to run a day.
