Can you do a transfer without mining a block?
No, it needs to be included in any freshly mined block.
Can you include an unlimited amount of transactions in a block to minimize the wasted energy?
No, it’s hardcoded to around 1 mb and since the average is 300 bytes, that translates to ~3000
Can you mine a Bitcoin without wasting an immense amount of energy?
No.
So, by math, you take that immense amount of energy and divide by ~3000 transactions.
You can’t just take in consideration the 3 watts used by your computer in the 300 milliseconds used to submit the transfer, need to consider the whole network
I would be happy to learn if it’s possible to transfer them without including the transaction in a block, that would be groundbreaking and then the electricity used would be 10000x less

please explain how to transfer bitcoin without mining a block, since the transactions are contained there.
You need to take the energy required to mine a block and validate it (a lot, could power a small town), then divide for the few transactions that could be included in just 1 mb.
They impose a size limit on the transactions that can be included, so even if tomorrow the transactions increase 10x, each block could contain the same limited number. Of course, if you only count the electricity used by your machine to send the transaction, it’s just a few milliwatts. The problem is all the garbage calculations that need to be done to actually validate it.

For a generic non personalized spam, IMHO it would be too expensive to generate and track millions of wallets. They could have placed a tracking pixel for much less (they didn’t, the email is just plain text)
If then it’s some targeted campaign, then yes, a dedicated BTC address makes sense as you said

It’s a conservative estimate, it’s even higher than that
Crypto-biased source: coindesk.com/…/how-much-energy-does-bitcoin-use/ (you would expect they downplay the number)
You can just take a calculator and do by yourself the math from publicly available stats bitinfocharts.com/bitcoin/
In the past 24 hours a block contains in average only 3500 transactions. Then that block needs to be validated by many other nodes in following calculations.
This is why it’s the most inefficient payment method, very slow (3500 transactions in only ten minutes), expensive for the user (transfer fees are high) and power hungry

enshittification happened to scribd, not bugmenot
scribd used to offer free hosting for all pdf files, then when they hit critical user mass, they decided that only paid users can download the (mostly pirated) PDF files. Literally profiting from piracy while pretending it’s designed for business.
