Notes:

You will need at least twelve Energy Tanks going in with the Gravity Suit on Normal mode to do this, so it is probably only useful in a 100% run.
It's actually possible to harvest energy from the Metroids in Fungal Halls A and B, then return to the Phazon Tunnel and continue bombing the blocks. When you go to Fungal Hall A, Fungal Hall B will be refreshed with new Metroids to kill, and vice versa, giving you an unlimited supply of energy if you feel like taking the time to get it.
With the Japanese, European and Australian versions' slightly altered Environmental Damage it will be easier to perform this trick in the Japanese, European and Australian versions of the game.
