> Cars monitor energy use through MPG. Datacenters monitor it as well. Why should crypto currencies get a pass?
cars spend energy to move. datacenters spend energy to compute things. bitcoin mining doesn't spend energy to process achieve some TPS, it spends energy to achieve certain level of security, so it's security per energy spent that matters, not energy per transaction.
if transactions or number of them are not an input to a bitcoin miner -- if miner will spand the same energy whether it's for 1 or 1 trillion transactions -- then energy per transaction metric is zero signal.

no, actually, it's an opinion. current financial system and fiat money cause immense externalities: war, corruption, hunger, crime, etc. bitcoin is an incarnation of money where security is expressed in form of energy spent - you no longer need to involve politics or any other human activities to achieve security and so a large incentive for those simply disappears. bitcoin doesn't solve those externalities, but that specific aspect of money is simply no longer contributing.
