Exactly, that's why if you're using this list to somehow decide coin X is more "efficient" than coin Y, then it's a foolhardy exercise.

For proof of work to actually work, the cost of the electricity has to be proportional to the total market cap of the coin. Otherwise, if the amount of work was low compared to the value of the network, it would be a strong incentive for someone to try to attack it.

"Efficient" could also be read as "I am willing to sacrifice x Wh to the gods of crypto wealth, where do I get the biggest return?"

That might even be a tolerable mindset if you happen to live in a cold place and the only tool available to keep you from freezing to death was electricity.
