Bitcoin is perhaps a rounding number today (my guess is that it is more than that due to Chinese miners not reporting energy usage correctly but could very easily be wrong), but what it solves is even less of a rounding number. Said in a different way to do all financial transactions on the blockchain would use a lot more energy then it currently does.

BTC does not require every single transaction to be processed on-chain in the way that you describe. Please refer to the Lightning Network.

  But then you are moving the goal posts, blockchain is not really needed for lighting.

That's not how it works, energy usage does not scale with the number of transactions.

  Uh, why not?
