There are generously 2k transactions per block. Block reward is 6.25 bitcoins. A bitcoin costs $30,000 so the block reward is $187,500. Amortizing over 2k transactions, each transaction is worth a smidge under $100, before transaction fees (which as you point out are two orders of magnitude smaller so don't really matter here). $100 is about the average US monthly power bill, and it doesn't seem unreasonable that miners making use of the cheapest energy around the globe would be paying 2.5x less than that.
