algorithms that sometimes are roughly the same too (SHA256 vs SHA3-256 vs scrypt)

Clearly you have no idea what you are talking about.
A scrypt hash is 4 orders of magnitude harder to compute than a SHA3-256 hash.

Apparently you forget what we are discussing here yourself. We are just comparing computational cost. We are comparing all values at the same time.

SHA2 and SHA3 have almost identical computational cost. Yet the "PoW Produced (24h)" in that chart is almost the same and ETH hashrates is 4e-6 times bitcoin hashrate.
Scrypt has higher cost than SHA2/SHA3 (4 times according to you) but the "PoW Produced (24h)" in that list is only 0.02 and hashrate (LTC) is 2e-6 times bitcoin's hashrate.

Daily dollar emission on the other hand is a good proxy for how much energy will be spent competing for those rewards.

The most accurate estimation of electricity cost is always going to be hashrate since hashrate is directly related to hardware that consumes the energy.
