At it's current usage where maybe 2-3% of the global population has ever actually performed a transaction on the bitcoin network, and next to no one uses it as their primary network for transacting, it used the equivalent energy of the entire country of Brazil, which has half the U.S. population (though less than half the energy usage)
To be clear, the energy usage is a function of price more directly than it is of actual usage, it just so happens that the price would continue to increase if people actually used it for real-world transactions.
I also don't think there's anything inherently immoral about energy usage. Bitcoin can theoretically help us access remote natural sources of energy and convert it to wealth instantaneously with just an internet connection when otherwise it would be infeasible to transport
Of course, there are ways the proof of work model is better too. There's tradeoffs both ways. But nothing offered by cryptocurrency makes up for the enormous energy usage of proof of work at scale, so the other consensus mechanisms are the only real, sustainable models for world-wide adoption
