They mean one transaction. Do the math. I did and it checks out. 300 kWh *per transaction*. Not per block. Per single transaction in the block. Yes, Bitcoin is *that* ridiculously inefficient.https://twitter.com/marcan42/status/953775357978591232 …

i really dont have time. You can easily find what i try to say three tweets before... :P I cant answer the same thing to every "supporter" of this non tech guy. What kind of media is this? The blind-tech fest?
If you're trying to argue that the number of transactions per block is variable (I think that's what you're trying to argue? You're doing a terrible job of it) the point is that's is a *maximum* number of minimum-sized transactions, and you can use that to do the calculation.

and that maximum therefore calculates the *minimum* bitcoin energy use if there's less transactions per block, bitcoin is even *less* efficient, so it doesn't really work as a defence

Maybe he's arguing that a single Bitcoin txn can "count" as many because it has many inputs and/or outputs. Which is still a useless argument, because the more inputs/outputs the larger it is, and the fewer fit in a block. At most a tiny constant improvement over many small txns.

you calculate transactions to bitcoin as a single input output this is wrong. Every AtM use 5520W. There are over 400,000 ATM to USA. That means that only in USA the ATM's uses 2428800000w

What exactly makes you think a single ATM uses 5520W? Here's an ATM datasheet. 260W idle, 410W during a transaction. http://www2.diebold.com/gssasupaes/cut_sheets/cut_sheet_files/Self%20service%20terminals%20-%20ATMs/BulkCash%20terminals/177443r02.pdf …
