Eth profits are more or less the same after the fork.
There was an issuance reduction but it also reset the difficulty bomb back to 14 seconds. No idea how there is more higher energy consumption, nothing has changed in that regards, wonder where you are getting this information from.
Basically unless you got cheap or free power, it wasn't profitable after the fork and neither was it profitable before. We need ProgPOW or ETH to go to like $400 a coin.
