It’s not double-spending energy. The chunk of energy you generate isn’t spent by you, it’s supplied to Bitcoin users to power their transactions. You only consume the second chunk of energy for yourself.
- tomxor 6y ago> to power their transactions That's purely artificial, it's unnecessary, this has been discussed to death. PoW is useless work. You aren't doing useful work you are randomly double SHA2ing energy back out into space just to play the lottery... oh look I found a nonce which hashes to less than the magic number, who cares, this has no material value, it's not functionally useful, it's contrived. PoW is not fundamental to blockchain or crypto currencies.
