> For Bitcoin, the most popular one, on the order of 100.000.000.000.000.000.000 of hashes get calculated to mine a single block, multiple trillion per second. Within ten minutes, only a single one of those 100.000.000.000.000.000.000 hashes is actually used, depending entirely on luck. The rest are thrown away entirely. They do not form part of the final hash or anything else, the energy spent on them is lost.

That's still more energy efficient than the regulat fiat system.

Is there electrical energy just burnt for no purpose in fiat systems? You are talking about efficiency, not absolute value. The transactions of fiat systems are orders of magnitude more than the bitcoin chain's.
