there is no energy requirement at all for either mining method. the protocols are energy-agnostic.
Incorrect. Bitcoin protocol is designed to distribute bitcoin to whoever provides the most energy (work).
it's all just guess-and-check. a raspberry pi could find the next block even today.
Agreed. Because they can't provide enough power to prove the required work.
i think you read a word that isn't there. the work of generating a nonce, hashing the header, and checking for leading zeroes can certainly be done by a raspberry pi in under the 10 minute block time.
A raspberry pi could verify a bitcoin block. It is EXTREMELY unlikely to find the next block.
unlikely, given the network hashrate, but not impossible.
A hash rate that requires 170TWh of electricity. There are no scenarios where this drops more than 99%, except for the destruction of bitcoin.
